Like I said, they are not all the Canadian versions. Only a few of them are. But the "Canadian" versions are just the same as the "U.S." versions, in most cases they just threw an extra French manual in the box. (A few of the Canadian boxes actually had French text, in addition to English, on the back of the box.)
EDIT: I just bought Addams Family (sealed) and Sonic Spike (sealed) for $47, shipped. Breaks out to about $23.50 per game after shipping. Better deal than TZD was, that's for sure...
