Computergeeks is a US etailer specializing in computer components and peripherals that are excess inventory, manufacturer-closeouts, overstock, and "slightly obsolete" inventories.

Shipping is high for Canada, but in some instances the prices of items are so low that it still comes out cheaper than anywhere else.

Factorydirect specializes in used, refurbished, new end of line, new surplus, and new closeout computer hardware. Check the fine print for warranty and returns policies.

"The Source by Circuit City" is the new name for Radioshack stores in Canada.

Tigerdirect.ca ships from the US (Illinois) via UPS. UPS is usually a recipe for disaster, but in this case Tigerdirect has made some arrangement with UPS to prepay customs so there are no hidden charges like UPS's normally 'extortionate' brokerage fees. Tigerdirect's site states "There are no Duties or Fees! Just pay the price of the product, plus any applicable tax".

And, in the event that you have to return something, you can ship it to TigerDirect's Markham warehouse. Call for an RMA and they'll give you instructions for shipping at no cost.
