My dad had a block heater in his Mercedes diesel years ago. It wasn't standard, but there was a coupon in the owner's manual for free installation at any dealer. Diesels have particular issues when it's cold, although I thought it was mostly the fuel thickening.
I was under the impression that winter-specific tires are required in Quebec, although I'm not sure about block heaters. Here's an article about a local utility giving away timers to help reduce power consumption with block heaters in Saskatchewan. Is it that much colder there than where you live?

I heard that parking lot outlets tend to be timed, with the on-off timing dependent on the ambient temperature.
