I'm going to write a serious answer to this, but believe me, this topic will end up locked, and I struggle pretty bad to not end up insulting your post.
Canada has a few "big" parks. La Ronde and Canadas Wonderland being the largest by far, and as I don't really know a lot about the others, I'll analyse these two.
La Ronde's lineup consists mainly of a Twin Woodie, a Batman Clone and a B&M Hyper. The Intamin Standup and Vekoma Boomerang are supposedly also main attractions. The park last added something in 2006, and I guess the customers will demand a new ride soon. Not knowing much about the park's financial situation, now that Six Flags are out of the picture, I think you can expect something medium-sized there soon. Perhaps an Intamin Accelerator or a GCI Woodie, or something from B&M, though I don't know what. It just seems plausible given the parks earlier B&M record.
Canadas Wonderland won't propably give you anything big soon. Behemoth was a major investment, and they have a solid lineup, type-wise. Still, I'd keep an eye out for a woodie.
As for new parks, propably not. If Canadians want to go to big parks, they head for the aforementioned two, or go to the United States where these parks are all over.
That was my two cents. And By the way, it's spelled Montu.
