This mine would permanently destroy an area that is a place of worship for our people, a cultural school for our children, and a bread basket that has fed our people for centuries.

Should Canada allow mining companies to drain and kill pristine lakes?

Wilderness lakes are at the heart of Canadian identity, and most people are surprised and shocked when they hear that the Canadian government is considering giving the green light to several proposals to do just that.

One such project is Taseko Mines Ltd.’s proposed Prosperity Mine at Fish Lake in central British Columbia. The Tsilhqot’in Nation, the Friends of the Nemiah Valley and many others have been urging the federal government to reject the plan — including the national gathering of chiefs of the Assembly of First Nations who recently joined the call.

Fish Lake is aptly named. Renowned for its 85,000 rainbow trout, the Tsilhqot’in people have fished, hunted, trapped here for centuries — they regard Teztan Biny (Fish Lake) as a sacred place. Fish Lake is one of the best places to fish in the Cariboo/Chilcotin. Grizzly, moose, mule deer, long-billed curlew, flammulated owl and other wildlife depend upon the lake.

However, Taseko Mines Ltd. plans to drain Fish Lake. If this happens, up to 700 hundred million tons of tailings and waste material — including toxic metals such as arsenic, mercury, lead, and cadmium — would be dumped into new a tailings pond created by the flooding of Little Fish Lake and Upper Fish Creek.

The impact of the Fish Lake proposal is grim. An independent expert review panel appointed by Ottawa recently panned the proposal. The expert panel concluded in its report in July that the mine proposal would:

• Create “high magnitude, long-term and irreversible effects” on fish, significant effects on grizzly bear, and other significant adverse environmental effects;

• Permanently destroy an important cultural and spiritual area used by the Tsilhqot’in people, and lead to long-term impacts on the physical and mental health of the Tsilhqot’in.

In many cases, the panel stated that it simply could not recommend mitigation measures for the severe damage it foresees.

This report is a remarkable finding, given that federal environmental assessments almost never turn down a project.

For example, a great many Alberta tar sands projects that seriously degrade the natural environment have received federal approval based on findings of no significant adverse environmental impacts, after mitigation.

In fact, in almost 20 years of assessments under the Canadian Environmental Assessment Act — including dozens and dozens of major projects — only two previous Panels have found significant adverse environmental impacts (the Kemess North mine in B.C. — which, like the Taseko Mine proposal would have converted a lake into a tailings pond — and the Whites Point Quarry in Nova Scotia). Ottawa rejected the projects in both cases.

One would hope that precedent would be followed, and that the Fish Lake proposal would be turned down. However, there are troubling signs. When Ottawa appointed the Fish Lake Review Panel, it refused to authorize the panel to actually make a recommendation against the project.

A cynic might suggest that Ottawa was seeking to avoid a repeat of the Kemess North mine assessment, where the panel recommendation against a similar proposal made it politically impossible for Ottawa to approve the project.

It’s just in the last decade that Ottawa changed the law to allow companies to dump mine waste into lakes. Four years ago, the Harper government approved destruction of two Newfoundland lakes, setting a dangerous precedent. Since then, mining corporations have applied to use 11 lakes as toxic dump sites.

Fish Lake and the other lakes across the country facing destruction raise fundamental questions about what we value as a society and what our laws should protect:

• Why do our laws even allow fish-bearing lakes to be converted into waste dumps for toxic tailings?

• How do we ensure that our government accurately evaluates the impacts of environmentally destructive projects and reject the most environmentally destructive projects?

• What priority do we place on cleaning up after ourselves and protecting our natural environment on which all life depends?

With the federal government seriously weakening environmental assessment in the budget that passed thismonth, and Parliament gearing up for a full-scale review of environmental assessment law in the Fall, Canadians need to answer these questions.

The survival of Fish Lake is an issue for all of us. In its decision about Fish Lake, Ottawa must heed its own independent expert review panel — and reject the lake’s destruction. But, equally importantly, Ottawa must amend the law so that fish-bearing lakes are off limits to mining companies looking for a place to dump their waste and maintain and strengthen Canada’s environmental assessment laws so that the full impacts of environmentally destructive projects are fully evaluated.
