finding places in canada is hard.
bigfoot is probably one of the best cooling unit distributors in canada.
Linky If u live in toronto, u don't have to pay shipping cuz u can go pick up your order.
currently, bigfoot only has vantecs, but u could ask for taisol.
for new cpus, go with
Razor Computers,
Netlink Computers,
PC Canada. I know for a fact that those stores ship around canada.
but if u live in toronto, there are tons of places like canadacomputers.com, icctcomputer.com etc.
good luck
