I call this meeting to order. We're going to continue with our study on the oil sands and Canada's water resources.
We want to welcome to the table again Cynthia Wright. She's had a busy week with us at committee on two separate issues. Welcome back. She is the acting assistant deputy minister for the environmental stewardship branch of the Department of the Environment. She is joined by Albin Tremblay, who is the chief enforcement officer, and Fred Wrona, who is the acting director general for water science and technology.
From the Department of Health we have John Cooper, who is the director of the water, air and climate change bureau in the healthy environments and consumer safety branch. He is joined by Roy Kwiatkowski, who is the director of the environmental health research division of the first nations and Inuit health branch. Welcome. We have Wadieh Yacoub, who is the medical officer and director of health protection, first nations and Inuit health, of the Alberta region.
Welcome to all of you.
We'll turn to our opening comments. Please keep them within ten minutes.
We'll go to you, Ms. Wright.
I'm here today on behalf of Environment Canada and my colleagues to describe to you some of the roles and responsibilities that we have as they relate to oil sands and to describe some of our priority work in this area.
As you well know, the management of the environment is a shared jurisdiction between the federal and provincial governments. At the federal level, Environment Canada's role relates to the management of transboundary issues, including those related to water, migratory birds, species at risk, and toxic substances.
Environment Canada has responsibilities under the Canadian Environmental Protection Act, the Species at Risk Act, the Migratory Birds Convention Act, and the Fisheries Act. We are also involved with activities that are enabled under the Canada Water Act, such as cooperation with jurisdictions on research and monitoring. Through this work we provide our knowledge and technical expertise to inform the decision-makers at all levels of government in Canada.
Slide 3 shows that there are three ways in which Environment Canada interacts with the oil sands. The first is through the fulfilment of our statutory and regulatory obligations. The second is through the provision of expert advice to regulatory authorities in the environmental assessment process. The third is through research and monitoring, including collaboration in multi-stakeholder environmental management initiatives. We'll describe a bit of each of these.
Next is slide 4. I'll speak briefly to our statutory and regulatory obligations under the Fisheries Act, the Canadian Environmental Protection Act, the Migratory Birds Convention Act, and the Species at Risk Act.
We'll go on to slide 5. Environment Canada administers subsection 36(3) of the Fisheries Act, which prohibits the deposit of any deleterious substance in water frequented by fish.
The Province of Alberta issues permits for the oil sands tailing ponds. One of the requirements of those permits is that there not be a discharge of water into the environment. The general prohibitions of the Fisheries Act, however, would still apply and could be used in the event of a spill or an unusual discharge. The department does monitor the oil sands activities. It has conducted 18 inspections over the past few years and has not yet found any violations of the Fisheries Act.
The Canadian Environmental Protection Act is a keystone piece of legislation to reduce the release of harmful chemicals in the environment. Under Canada's chemicals management plan, 98 high-priority substances have been identified as potentially substances in the oil sands sector. These substances are currently being assessed. The act has other relevant provisions, including reporting requirements under the National Pollutant Release Inventory, and emergency provisions that include the requirement for emergency plans for a number of substances associated with the oil sands.
Next is slide 6. The Migratory Birds Convention Act and its regulations ensure the conservation of migratory birds. Specifically, the act prohibits the damage or destruction of migratory birds, nests, and eggs. It prohibits the deposit of substances harmful to migratory birds in any waters frequented by migratory birds. It is under this act that Environment Canada laid charges against Syncrude for allegedly depositing, or permitting the deposit of, a substance harmful to migratory birds.
The Species at Risk Act, as you well know, was created to protect wildlife species from becoming extinct by providing for recovery of species due to human activity and by ensuring the sound management of species of special concern so that they don't become endangered or threatened. The act includes prohibitions against the killing, harming, harassing, capturing, or taking of species at risk and against destroying their critical habitat.
Slide 7 relates to how Environment Canada provides expert advice in support of federal environmental assessments. This advice includes technical advice related to water quality, quantity, and prediction modelling; ambient air quality and mine fleet emissions technology; cumulative effects of oil sands development and the need for integrated monitoring; and migratory birds, species at risk, and their habitat. Environment Canada has been involved in about 12 environmental assessments for oil sands projects, including five joint panel reviews.
We will go to slide 8. Environment Canada has extensive expertise, and we undertake to share that information broadly. We carry out ecosystem science in this region of the Mackenzie Basin, and we collaborate with the provinces, territories, university, industry, and other stakeholders. For instance, we are engaged in the Cumulative Environmental Management Association.
We also chair the Mackenzie River Basin Board and conduct research in support of the board's primary goals. We are engaged in research related to ecosystem impacts, including downstream effects on such things as water availability, ecosystem flow needs, and contaminants.
Environment Canada also led earlier research conducted in the oil sands region as part of the northern river basins study, the northern rivers ecosystem initiative, and the Peace-Athabasca delta technical studies. This work has influenced a number of industry regulations and operating standards that apply to the oil sands. We've also undertaken targeted research on oil sands-related contaminants.
Slide 9 shows a number of key Environment Canada priorities that, going forward, will help support decisions related to the oil sands activities. For instance, some of our current research includes continuing the assessment of toxicity and potential effects of tailings pond waters, assessment of acidifying emissions from oil sands and their impact on lake ecosystems, and assessment of the impacts of changes in flow and water levels in the Peace-Athabasca delta.
As I previously mentioned, we also have extensive work under the chemicals management plan, which has organized work related to the oil sands sector and identified 98 potential substances whose risk we are currently assessing. Some of these substances are related to the mining and extraction activities, such as purchased drilling fluids, and others relate to upgrading activities. As risks are identified, we will manage those risks, and of course we continue to carry out our enforcement responsibilities.
Thank you, Mr. Chair.
:
Thank you. I would like to thank the committee for inviting Health Canada to appear before you today.
We can move to slide 1 to give a sense of how I'd like to approach this. Initially, I'll briefly discuss the roles and responsibilities of Health Canada as they relate to health and water. Then I'll move to a consideration of the Athabascan region and the particular potential sources of health risk associated with that area. Third, I'll briefly discuss some of the health concerns that have been raised. As you're aware, Dr. John O'Connor and the people of Fort Chipewyan have raised concerns about cancers. Some studies have looked at this issue and have come to certain conclusions, and I'll briefly touch on those. Finally, I'd like to discuss the way forward and give conclusions about where we need to go in the future.
One of our primary roles in Health Canada is drinking water quality. It's important to understand that responsibility for drinking water quality is shared between federal and provincial governments. The federal government has responsibility for the safety of drinking water on passenger conveyances--ships, trains, and airplanes--and on federal lands.
In the context of first nations, Health Canada works with Indian and Northern Affairs Canada to assist first nations in dealing with the issue of safe drinking water. To be more specific, first nations have day-to-day responsibilities for the provision of drinking water, the operation of the treatment systems, and the testing that goes along with that. Health Canada provides advice and ensures that monitoring programs are in place on first nation reserves.
In terms of shared federal, provincial, and territorial management of drinking water, Health Canada is responsible for developing the risk assessment of chemical, microbiological, and radiological contaminants. These guidelines are used as the basis for standards and regulations in all the provinces and territories. In other words, these become enforceable standards in all jurisdictions across Canada and provide a common benchmark for safe drinking water.
I would like to give a quick overview in terms of how effective this approach is. I would suggest that since the Walkerton and North Battleford crises in 2000 and 2001 respectively, both the quality and the management of drinking water have improved substantially. This improvement includes the adoption of a multi-barrier approach, which essentially means that it's not sufficient just to have a good treatment system or a treatment plant. Instead, you really need to focus your attention on major issues, such as the protection of the source water of lakes, rivers, and groundwaters. This is key to protecting health. You must also ensure that you have operators and training in place.
The provinces and territories have all updated their legislation, regulations, and policies since 2000 and 2001. That said, we still face challenges in drinking water. In particular, I would point to water supplies in small communities. Those communities lack the capacity and the resources to provide the treatment and protection to which larger communities have access. Health Canada works with provinces, territories, industries, NGOs, and the academic community to try to move this issue forward so that we can address this challenge.
Health Canada also has responsibilities related to food. They are primarily in relation to the level of exposure to chemical contaminants in retail food, which is regulated under the Food and Drugs Act. However, in the context of the meeting here today, I think the issue is more in terms of country foods. Health Canada conducts risk assessments of country foods and provides advice in terms of health protection to provinces so that they are able to issue advisories specifically in relation to the consumption of fish and other food taken from the wild.
Health Canada also has responsibilities related to environmental contaminants. Cynthia Wright has already gone into the Canadian Environmental Protection Act and the chemicals management plan, which assesses and manages chemicals considered at risk and looks at industrial sectors, so I won't add anything to that area.
Finally, Health Canada has a role in environmental assessments and in identifying the potential health risks associated with development projects.
Now, if I can turn my attention to the Athabascan region and the potential sources of health risk, I'll give a brief overview of that.
Certainly there are contaminants of concern. These are mostly in the source waters and these derive from natural sources, such as the bitumen that leaks into the rivers and lakes, and also arsenic and mercury that come from natural sources. But the Athabascan region has had a history of development that includes a uranium mine that I understand is no longer in operation. There are pulp and paper mills, the agricultural sector, and of course, the petroleum industry, the oil sands. All of these factors contribute to the overall quality of the source water, which is a primary concern.
Accordingly, when we're engaged in environmental assessments, our advice is to focus on source water quality monitoring and protection, the prevention of leaks and spills; and if there are leaks or accidental spills, it's important to notify downstream treatment operators and citizens of a release so they can take action to prevent any health risk. Having said that, there are issues with source water quality. The quality of drinking water is good in all the communities downstream of the oil sands.
I'll move now to country food. Yes, there have been issues with country food. There has been an advisory issued by Alberta since 1990 that relates to the consumption of walleye, and it's related to mercury contamination.
I'm sure the committee is aware of Dr. John O'Connor's concern--and the community of Fort Chipewyan has raised concerns over the years--about the frequency of cancers occurring in the community, rare cancers such as bile duct cancers and colon cancers. There was a preliminary and fairly limited study presented in 2006 that indicated that there were no significant increases in the cancer rate.
Subsequent to that, a more rigorous and complete study was conducted by the Alberta Cancer Board, and they concluded that the observed rates of cancer, the rare cancers, the bile duct cancers, were within the norm, not outside the expected range of these cancers. They also did indicate that the overall cancer rate was slightly higher than expected. The conclusions they reached or the explanations they linked to that finding were that this could be due to a simple matter of chance because of the very small sample size, it could be related to increased detection because of the more rigorous examination of the charts and medical history of the community, and it could also be related to a real health risk.
In conclusion, the study, at least so far, indicates that the rare cancers are probably within the expected range. There's indication that the overall cancer rates may be higher, and we would suggest that this needs further study.
The treated drinking water is safe; however, drinking directly from source water would not be advisable. In terms of the way forward, clearly, protecting source waters is key and preventing leaks and accidental spills is our priority. I think all of us do not want to see any added contamination of the system. We think it's very important that the province continues to monitor the source and the treated drinking water and that governments take regulatory action as required.
In terms of Health Canada, one of our priorities is to continue developing guidelines and to identify and assess and manage contaminants under the chemical management plan. We have a continuing role in providing advice and support in any further cancer studies, and certainly in terms of working with first nations communities to ensure safe drinking water and improvement of health status.
Thank you very much.

The Alberta Cancer Board did a rigorous study that was reviewed by peer reviewers from across the world on the methods used and the results. Every single peer review is published on public websites. You can read the reviewers' comments on the study.
We at Health Canada have concurred with the findings of this study. We believe the number of cases is definitely within the expected range. First nation cancer rates are usually below the provincial average for cancers across Alberta, except for cholangiocarcinoma. Cholangiocarcinoma is known to be higher in native Americans and indigenous people around the world, and in Alberta the rate of cholangiocarcinoma is two to three times higher than for the rest of Albertans.
So it definitely is the case that it is within the expected range. The fact that two cases happened one after the other in the next year is probably, likely, due to random variation and chance because of the small size of the population.
As for the colon cancer, the physician submitted 12 cases of colon cancer that he said he'd seen. From the 12 he submitted, only three were confirmed to be colon cancers. Because of the rigorous work of the Alberta Cancer Board, they found another three that he had not submitted.
There definitely are small increases in the rates of the other cancers that the board reviewed--blood cancers, lymphatic cancers, soft tissue carcinomas. However, even for those cancers, these are the number of cancers, not the number of people. Some people have actually more than one cancer.
I submit to you that the findings are valid. They have been very well reviewed by independent people. They're the cancers we need to follow. That's why we at Health Canada concur that we need to continue monitoring the cancer incidence.
If these rare cancers happen again, that truly will be a cause for concern and follow-up in a more rigorous way. That's why the Alberta Cancer Board has made a great effort to visit the community and sit down with the local physician who currently is actually reporting cancers. Dr. O'Connor did not report these cancers when they happened. Now this current physician has the form, and he currently reports everything to the board.
I submit to you that the next step, for sure, is to continue monitoring closely to see whether these are true increases in rates or these are true random variations, as many cluster investigations like these have found around the world.
:
Thank you for the question.
The number one priority for us in Health Canada is to protect first nations and Inuit health. The response of Health Canada, as soon as Dr. O'Connor phoned us, was to immediately instigate an investigation to follow up on the claims of a cluster of cancers. This was done in cooperation with Dr. O'Connor, and actually it has been three years to the day as of yesterday since we did that. We immediately flew, upon his agreement, to Fort Chipewyan to meet with him, which happened on May 17, 2006, at which time Alberta Health and Wellness, Public Health Agency of Canada, and Health Canada representatives met with Dr. O'Connor to investigate his concerns. At no time did we suggest that his concerns were invalid or anything like that.
We pursued with the college other things that caused us concern, because we are all members of the College of Physicians and Surgeons, and under our ethical and professional obligations, which we all meet as physicians, we spoke with the college. The college rulings have not been made public. In particular, the one you refer to is still pending investigation.

Actually, the report we tabled focuses mostly on drinking water in federal jurisdiction and deals with the guidelines and process, and also the provision of drinking water on federal lands and passenger conveyances.
Certainly there have been substantial improvements over the past few years. There's an interdepartmental working group that has published a guidance document on the management and safety of drinking water on federal lands, including national parks, penitentiaries, and Canadian Forces bases so there's some consistency in benchmarking of practices. This is currently being updated. It's very important that we ensure there are good practices. Although we have no responsibilities as the Department of Health for the practices of other departments, they recognize the importance of working collectively and coming up with common systems for the protection of people working there and also visiting their federal lands.
In the same way, certain actions have been taken to improve the safety of drinking water on public conveyances. In terms of drinking water guidelines, there was criticism in 2005 that these were out of date because they were 15 years old and our process was slow. All these factors have been addressed.
We work with the federal-territorial committee on drinking water, so there's a consistent set of standards applied across the country in terms of protection of drinking water. We develop the guidelines, and they adopt them and enforce them. Some jurisdictions, certainly Quebec and Ontario, will take certain guidelines and enforce standards that may be slightly more rigorous.
Our department has been involved in numerous technical studies since the early 1990s involving quantification of the ecological state, contaminant levels, and sources of contamination in the Athabasca system. As the committee members know, the Athabasca River flows through a geographic area with multiple developments and municipalities. In that basin we have pulp and paper development, forestry, oil sands development, and other activities.
The studies we've been involved in, along with other departmental colleagues and university collaborators over the years, have improved our understanding of baseline conditions of these particular types of contaminants. Over the years, through our research efforts and the various monitoring programs, we have seen improvements in levels of contamination, particularly related to processes such as pulp and paper development in the area, and so on.
The complication we have related to the oil sands was mentioned. We have conducted research as part of these initiatives, trying to assess the role of natural hydrocarbons and the effects on the environment, as opposed to ones that are from actual oil sands activities. We published some preliminary results in this vein in 2003 and during the northern rivers ecosystem initiative, showing the potential effects of natural hydrocarbons on fish health and ecosystem health.

Thank you for the question.
The Alberta Cancer Board study was a study to describe the incidence of cancer and not the risk of cancer. That's a major difference, because it's not conclusive at all about why the cancer has occurred.
I agree with you that it is of utmost importance to follow up, and it is our intent in Health Canada to work with the Alberta Cancer Board and the Fort Chipewyan Nunee Health Board Society to continue monitoring the incidence of cancer.
In all the situations that have been reviewed, especially the rare cancers, in its report the board reviewed the medical charts, and all the risk factors contained in those two cases were the known risk factors. We are not saying there is no relationship to the environment or anything like that; we're just saying this requires further monitoring.
Our plan of action is to concur and work with the Alberta Cancer Board in continuing to monitor the incidence of these cancers. We will ensure that the cases of cancer that are identified in the community by the physicians are followed up. We will ensure the continuation of the health promotion and disease prevention activities to prevent cancer and promote healthy lifestyles, because lifestyles could very well be part of the picture of the cancer incidence in the community.
We concur with the actions proposed by the Alberta Cancer Board, and we will work with the community and collaborate wherever we can.
I want to go back to my last series of questions for Environment Canada. I'm having a very hard time squaring the circle.
We have a multi-stakeholder group set up by different orders of government, which has as its membership governments, aboriginal elders, non-governmental environmental organizations, scientists, and university representatives. I can't remember how large the group is. A year and a half ago they issued an urgent letter to, as Ms. Wright has pointed out rightly so, the Province of Alberta.
The federal government may not fund CEMA now, but I understand it used to. It certainly must be helping with research. It must be sharing its data and its analysis. But 83% of CEMA's budget is funded by industry itself, and a letter is issued saying we want to put a hold on this. We want a moratorium on new resource tenures until January 1, 2011. In fact, it's so serious that, four months later, CEMA sent a second letter to the Government of Alberta, again calling for an interim moratorium on new resource tenures.
The federal government, as I understand, Ms. Wright, has a representative on CEMA.
