Since you're in Canada, I suspect this car has the engine block heater in it. It takes the place of one of the rear freeze plugs, and is common to leak on older examples. That is the only thing other than the heater core drain, located in the firewall just behind the engine toward the pasenger side. Normally, when the heater core is leaking, you'll either get a sweet smell inside the car, or steam on the windshield. However, since you're not letting the car get warmed up, you may not get the smell.
