Now THAT was fun. I discovered a fine forgotten building in Toronto not long ago, and crossed Church Street to read the magnetic (to me) blue and gold plaque. This unusual building (more on that later) bore the sign JAZZ. A jazz club, I assumed.
No, turns out to be apartments - if you hurry there are several available right now in the $1950 to $3350 range. I'm afraid I have no more information, as I was caught up in the account of the Athenaeum Club (1891) and Labour Temple (1904)
'Athenaeum' rang a bell; weren't they akin to the Mechanics' Institutes (here's a Toronto example).which offered reading rooms and technical and adult education for those men seeking social and economic betterment? Many evolved into public libraries. Institutes, not the men. And I use 'men' for reasons unfuriatingly obvious in that day.
Here's where the fun starts. The first item in my search for Athenaeums (ae?) turned out to be one of my own. In the February 2016 issue of the newsletter of the Hastings County Historical Society (doubtless you still have the issue) I warbled on about the Atheneum in Belleville, Ontario. Modelled optimistically on the Athenaeum Club, that exclusive arts and letters club of London, England, Belleville's offered improving fare from 1859 - 1866. Spoiler: it failed and became a skating rink. Here's a link to the Outlook article.
But back to 167 Church Street.
