Samuel Lount and Peter Matthews
"Be of good courage boys, I am not ashamed of anything I've done, I trust in God, and I'm going to die like a man." - - Samuel Lount. On April 24, 1824 the cornerstone of York's second jail was laid on this site. In the aftermath of the Rebellion of 1837 close to ten thousand people stood on this spot to bear witness as Samuel Lount and Peter Matthews, two of William Lyon Mackenzie's most loyal supporters, were hanged on April 12, 1838 on gallows adjacent to the jail. By 1840 a new prison, the Home District Gaol, was set to open on Berkeley Street and the old jail was to be incorporated into the York Chambers Building which stood until 1956. The last hangings in Toronto were at the Don Jail in 1962.
