In Canada you can find escort camp fuel or ronsonol lighter fluid that will work for extracting and precipitating DMT. Canadian stores don't sell anything called Naphtha like they do in USA that I've seen.
If you can't find those specific one, you can look on the back and it should say "naphtha" on it somewhere. Rona, Home depot or Canadian tire has them often. Home hardware and even save-on has them in bigger stores.
Most important is the additive test. It should be 100% clear and smell chemically, not of rotten eggs (woft to smell, don't stick your nose in!) When a small amount is left to evaporate (outside) it must leave behind nothing at all, no residue, no smell.
