Newsflash: most people are not Christians.
Yeah -- some people are...Canadians.
Traditionally the big sale season in Canada has always been the Boxing Week Sales immediately after Xmas. This is the time to get next years wrapping paper and decorations ultra-cheap, and to pickup the stuff Santa didn't bring you for a discount. For many households, it was both the time to stock-up for next year, and to get some big ticket items when they were cheap.
For the last several years some chains have been trying to push "Black Friday" sales in order to compete with online retailers in the US, and people who go cross-border shopping for deals. To be honest, I don't know a single person here in Canada that gets all that excited for Black Friday sales here in Canada. It's not a holiday for us, so people are only going to get to the stores on the Saturday or Sunday at best, and it feels like an artificial, unauthentic sale imported from the US. The "deals" generally aren't that great, and you don't get lineups outside the doors (that I've seen) or people trampling each other to get what few "door crashers" may exist at any given store.
As a lifelong Canuck, you guys can keep your Black Friday sale. If I need something I'll catch the Boxing Week sales like my parents and grandparents before me.
 - Yeah, I'm probably just going to order from Amazon. Screw the crowds and parking! :P
