The study found that the highest estimates of any type of child marriage, including formal and common-law, were in Saskatchewan (0.5 per cent)

This isn't just on diversity. There are Hutterite and Mennonite colonies out here in Sask where it's not uncommon to see a 15 year old girl getting "married" to a 30 year old guy. Same thing goes on on reserves.

The Eastern provinces (Ontario, Quebec and Atlantic Canada) have the lowest rate of child marriages, despite having the highest number of new immigrants.
