Port Credit Pets, Pet Mart, and Big Al's on Dundas (all in Mississauga) sell PAM. As well, vendors at the Ontario Reptile Expo sell them from what I've seen.
BTW, I wasn't getting upset with you. I just didn't understand how it wasn't legal for sale in Canada if I've seen it everywhere. I know pesticides are illegal in Ontario now, I just wasn't aware it should affect something like PAM
