Wow that sounds like a lot of work. I really don't think all that is necessary, at least not for Toronto. I "stored" my car from early December to early March. That's 3 months. I drove the car twice in that time, thus every 4 weeks, for 20 km or so just to keep it loose, overinflated tires a bit (40 psi), and kept the tank full to prevent condensation. Other than that, when I pulled it out of "storage" last week, I just adjusted tire pressure, started it (it always fires up immediately, no battery charging needed), and drove.

If you are leaving the car untouched for 6 months or more, maybe more precautions are required. But if it is stored indoors and driven every 4 weeks or so for 3 months, I don't think there is cause for more.
