It's actually very difficult to buy it Canada unless you are a lab or industrial user. Even then, there are a lot of regulations tied to it's sale and use. There are many reasons why this is... and I don't understand many of them. In the US, denatured alcohol is readily available at big box stores, etc.
Our closest alternative in Canada that is readily available is Methyl Hydrate (methyl alcohol in solution), more commonly known as gas line antifreeze! I would be careful using methyl alcohol as it's toxic. Wear heavy rubber gloves, safety glasses, and use it in a well ventilated area. It's really no more dangerous than handling other solvents or chemicals if you take precautions.
A little off topic, but this is actually a really interesting topic, and finally my chemistry background has an application on the Rogue forum!!
It's a pretty complex issue, but basically denatured alchohol is a category covering hundreds of substances used for commercial and industrial activities because of political will - denatured alchohol is poisionous by design so that humans are not tempted to consume it and as a result it is much easier to control and regulate. If regular ethanol were used in common commercial processes, it would make it's way into black market human consumptive purposes, it wouldn't be able to be sold in regular department stores, and the list goes on and on. Without Government regulations this stuff wouldn't even exist, and there would be a few less poisonous substances to worry about, but you can imagine the alternative health effects of having consumable highly concentrated alchohol on every store shelf.....
A common example in Canada and US is rubbing alchohol, which is denatured ethanol....it has additives to make it poisonous and taste terrible, regular ethanol would work just as well but then of course people would chug it for the buzz. Another example is camp stove fuel.
Anyway, the point is be very careful with any solvents, all too often we take these substances for granted because of their ready access, but most are highly poisonous and even carcinogenic, so just follow good safety procedures.
