Hello: We don't have as much research on Freemasons in Canada as in the US, but it was a popular movement among English Protestants. In the late 1930s, for example, Toornto had 76 lodges attended by over 26,000. In 1920, 9% of Ontario's adult male population were Masons, a figure that compares to the US. Statistically, I think that there were more Masons than members of any other single fraternal organization, including the Loyal Orange Lodge. So the chances of a member of the Sons of Temperance being a Mason were fairly good. Greg Marquis History and Politics University of New Brunswick Saint John Greg Marquis History and Politics Dept.
