The low birth rate in "Catholic" regions such as Quebec, France and Italy proves that lay Catholics with modern educations have no trouble doing what is in their own best interests regarding birth control. 

In any case the RCC, like other brands of belief in Imaginary Supernatural beings, is literally dying in Canada, as older zealots die off without recruiting enough new zealots to keep temple roofs from leaking or the heating plants running in winter. "No Religion" has already overtaken "Catholic" as the top response when Stat Can pokes its nose into that aspect of our private lives, without adjusting for the lie rate. People give socially conventional answers. About 1 person in 2 who says that they go to church regularly and gives tithes is lying.

The sad irony is that the RCC encourages abortion by teaching that an abortion is a sin of the same magnitude as taking 1 active birth control pill, or 1 of the 7 placebo pills in pack, using a condom, or using a pessary with spermicide.
