I have recently moved from Sweden to Canada. In Sweden, I always bought ethanol for my trangia ethanol stove at petrol stations. Where can I buy such ethanol in Canada? Is it sold at petrol stations, or will I need to visit more speciality stores? What is the colloquial name?
I did find ethanol at Canadian Tire (in downtown Toronto).
However, they only had a large bottle (almost 4L), so it's not suitable if one is already on their way; you should still get a smaller bottle and find a place to store the larger container.
Ethanol is usually sold as bio-ethanol in Canada, although, strictly speaking, it is really denatured alcohol (i.e., it has an additive to prevent people from drinking it). While you can get it from Canadian Tire, Home Hardware, Lowes, Rona, Ace Hardware, and Walmart, it is generally more expensive than methanol.
Note that methanol (aka methyl hydrate) burns just as well in alcohol stoves. You can get 946ml bottles of methanol from Canadian Tire, Home Depot, Home Hardware, Lowes, Ace Hardware, and Rona. You can get 500ml bottles of methanol from Canadian Tire, Home Hardware, and Rona. And, of course, it's cheaper to get 3780ml containers. I recommend getting small bottles to carry on trips and large bottles for refuelling the small ones.
For other names, see What are the different names for and sources of alcohol for my stove?
I live in British Columbia and I just purchased some denatured alcohol at Ace Hardware in the Lower Mainland. The brand is Klean strip. Ace Hardware does have locations across Canada, hopefully one near you.
When I couldn't find a Canadian Tire, I bought "rubbing alcohol" in a pharmacy. Works as well.
