Greetings; If you go on to the Canadian sub-forum of ECF, you can request a list of Canadian e-liquid suppliers, and this list may point you directly to DIY suppliers (I can't remember). If I understand correctly, you'll need 5 posts in the new members forum before you can post anywhere else in ECF, so you'll have to make that minimum before you can request the list.
But, as suggested above, Canvape is an excellent place to start, it's a very highly regarded vendor. At Canvape, you'll need to create an account, and wait for it to be processed, before you can access nicotine produces on the website.
Regards
Glenn
Edit: P.S. Welcome to the forum btw.
