Plan sounds good overall, but when was the last time you travelled from Ottawa to Kingston? Thats 2 to 3 hours on a good day with the roads blocked with zeds, cars and god knows what else you can count on not being able to take the 401 or 413. If you want to make it to Kingston, plan on using the canals and lakes, avoid the roads.
As for heading to the Rockies... seriously do you really think you could make it that far its a 3 day drive? I would aim for something a little closer, say northern Quebec. Of course if that is were you are headed in the long term why not just head there right off the hop?
Oh yeah I know how bad the roads will be in an outbreak, I knew I wouldn't be driving there right from the beginning. The canals idea I hadn't considered though I'll keep that one in mind for when the time comes.
The trek to the rockies will be very long and dangerous and so I'd like to avoid going there altogether if I can, it's more of a last resort for the case that the military can't suppress the outbreak. I chose the rockies because they provide a lot of natural barriers to keeps out zed's and deter raiders and bandits, something I don't see me getting in northern Quebec, also the higher altitudes will be colder and zombies will be less likely to make it that far without freezing.
