Pickings are slim up there for Christians. The Catholics must be doing something right, given recent attacks on them. The PCA has planted a few churches (and recently approved the formation of a Presbytery of Western Canada). The Anglicans, for the most part are a lost cause, as are those that joined the United Church. The Southern Baptists are trying to plant 1000 new churches in Canada by 2020.
You've got that right - though maybe no slimmer than in many parts of the U.S. .....
