In the best case scenario we might end up with two blocks: a large irreligious population on the one side, and another segment of the populace that is religious on the other, with the difference that the religious block will be considerably more devout than it is at the moment.
Right now the two thirds to three quarters of Canadians who report a religious affiliation are very predominantly people like my parents and my in-laws. They are moderately Cafeteria Catholic, and these "Cafeteria" types exist in other older Christian religions as well, and to some degree even in the Jewish community.
Without getting into too much detail, one of the main characteristics of these types of people is that they don't think that wider society should reflect their religion's beliefs. They have a high level of acceptance for a pretty secular society and institutions.
Most of these people are older, and what is happening in the generations younger than them is a split between those who abandon religion altogether (boosting the irreligious demographic) and those who are left in the religious category (increasingly dominated by true believers as all the softies have left the ship).
Add to this the fact that immigrants to Canada (with the exception of those from the Far East of mainland Asia) tend to be more religious than native-born Canadians, and you have a little armchair Acajack futuristic theory served up just for you!
