? Best T.O. store for IT network tools and supplies?

Hi, just wondering if anyone can tell where in Toronto I can find a walk-in store for all things computer and networking related? I recall going to one in the west end years ago that had all sorts of cabling, jacks, testers, crimpers... anything and everything to build in one huge shop. My searches have turned up smaller shops like Canada computers whose website may have everything... but the stores themselves have a fraction of that in stock. Basically I want to nerd out and 'browse' a computer parts and supplies warehouse... a one stop shop.

Thanks!

Ps. This post comes after a lot of searching from the couch, I'm just lazy and don't want to drive to multiple small places
