Depends on your provider - some providers have worked very hard to try and keep Canadian traffic in Canada with a huge focus on peering.
Maybe it's not so bad in Ontario, but in Alberta it's a compromise no matter which ISP you choose. Some have better routing to the west, and some have better routing to the east. No ISP has good routes to both east and west.
In general, if your ISP is Telus you have better routes to the east than anything in the west. For the most part, anything in the west ends up being routed through the east, which is obviously terrible.
If your ISP is Teksavvy or Shaw, then you've got good routes to the west, but your routes to the east are terrible.
If you want, post up a list of various IP addresses from a mix of eastern and western locations, and I'll run some traces comparing Telus and Teksavvy (unfortunately I don't have a Shaw connection anymore as it's not available where I am).
