We do not have any windfarms that I know of.

I think I saw something on CBC one night (Venture, maybe?) that talked about new windfarms going up on the Gaspé peninsula. I found a story about windpower in general, which mentions that project, on the CBC website: http://www.cbc.ca/consumers/market/files/environ/windpower/index.html

On the other hand, most of Canada does get its electricity from hydroelectric power. Most provincial electric companies are called "Hydro ______" or "______ Hydro". For example, there's Hydro Québec, as belM, pointed out, Manitoba Hydro, Newfoundland Hydro, Ontario Hydro... In Ontario there are some nuclear plants (which I assume are the Candu reactors, which are safer in many ways than the type which was used at Three Mile Island, see http://www.ncf.carleton.ca/~cz725/ for much more information).

Since my university education has been in physics and radiation physics (although now I'm in physical oceanography), I've had an opportunity to learn about nuclear power from people who know what they're talking about, rather than the scaremongers who don't know a thing about radiation physics. And I'd say that, thinking in a risk-management kind of way, the small risk of a nuclear accident is probably preferable to the guaranteed illnesses and deaths caused by burning coal. The unsafe plants probably need to be shut down and redesigned, undoubtedly, but nuclear energy isn't necessarily worse for people or the environment than burning coal.

The fundamental problem with all this is that unless the demand for power stops increasing, people will just have to live with the consequences of their thirst for electricity, be it hydro-, wind-, or nuclear- generated. You can't have your cake and eat it too!
