Croft Street
Once known as Ulster Avenue, this narrow lane was re-named in 1908 after John Croft, sole fatality of the Great Toronto Fire of April 19, 1904.
On May 4, Croft, a 38-year-old explosives expert, was clearing ruins near Front and Bay streets when a charge he had set failed to detonate. As he attempted to disable it, the charge exploded. Croft died of his injuries the following day. A husband and the father of three, he was buried in Mount Pleasant Cemetery.
