Help SN in Canada?

[Wothoki]

Hi, I live in Canada and I'm trying to get my hands on some SN(Sodium Nitrite), does anyone know where I can find some? I tried Amazon but it doesn't seem like they sell it.

Brand new account, no posts, cant even accept P.M. Good luck you will need it (No ones going to give up the few sources left)

That's fair too be honest, do any tips on how to improve on that side of things?
