It's not illegal to have just illegal to sell in Canada. If however it ships from south of the border there's no problem. Amazon.ca has it but an a very high price.I remember when "Bens" had this oily stuff that was 95% Deet, and it was awesome. Then they made a law that said it couldn't be more than 30%. F'n sucks now. I'd love to get my hands on a case of the good stuff......
These folks may ship internationally.
