Ontario had Conservative party premiers continuously from August, 1943 until the June, 1985 election. Pretty much everyone in a power position in business and politics during that period was from a pre-boomer generation. These were the 'old school' conservatives who believed that government had an obligation to impose morality on the general public. All of them are now dead.
Older guys on this board will remember that Ontario strip clubs were 'topless only' in 1985, and possibly into early 1986.
Ontario population growth chart:
Religion in Ontario, 1981 - 2021:
The number of people who identify as Christian declined by only 4%, but Christianity's 'market share' dropped by 41.6%. Irreligion has increased by 714%. My guess is that the majority of this group is people who have abandoned Christianity for themselves, and those who have not imposed Christianity on their Children, with a smaller chunk of 'ham-eating Jews'. There probably aren't that many atheistic Muslims.
