Hi Penn,
You may also want to contact the City of Toronto. I believe most fire departments are part of City or Towns public services and the municipal office may have some records. Toronto has changed quite a bit over the years as well taking in many of the surrounding cities and town, each with thier own fire department(s), ie North York, etc . Toronto proper and what Toronto is now quite different than back then. The Toronto Library system may have some info as well. Hope that helps,
