Thanks I have found the Montreal "F1 camping/parking" and it looks handy for the city.I’d say don’t miss Ottawa, if available the parliament tour is excellent. Montreal is much more metropolitan, but well worth a visit. Some amazing churches around Montreal, plus as has been said the park with the F1 track. Last time I was there the track could not be seen for snow and the temperature was -20! I think it may be better for you.
