I like Hamel's. I have had good service from them a few times. The quality of their merchandise is excellent.

A new online shop that was at a retreat that I was at recently is called "Quincy's Quilting". The ladies are fantastic and the quality of their product is excellent as well. Free shipping within Canada on all orders.

Recently I found this fantastic list called "The Big List of Online Canadian Fabric Stores". This should keep you busy!
