DigiKey.ca My recommended Canadian Supplier. over-nite delivery, free shipping with $100+ orders, insane amount of components and products.
Mouser.ca my second choice
some parts I cannot find like the “vertical panel mount” pots and other rare components I just order from “Thonk” or “Rapid Online” it’s actually fare pricing and sometimes cheaper than Canadian suppliers. Like 1/4" jack sockets I get from Thonk. 
plus they give awesome stickers, you just have to be patient with the mail.
Please add more input :
