As the title says: I am wondering should I solo travel to Montreal and Quebec City while I am visiting Toronto or save it for another trip (could be never or far in future).

I am planning to do my travel to Canada while I am still close to the border (grad school and future plan is all the way down South US). I will drive to Toronto spend 3 days there including the time at Niagara. However I was also planning to do all in one (as I already cross the border, make it to Toronto, why not go a bit more to Montreal and Qubec City).

However the reason I am hesitate and indecisive is due to parking issue a bit of cost and worry about time crunch so my travel not as effective as I thought. As my car is 2022 Lexus (not fancy but one of the hot target for car theft/looting; even in parking garage) and I am leaving toronto for at least 4 days. I can counter this by security measure like camera or wheel boots but still one of the cons or reason not to do so. The cost issue is more about pros if I don't go, basically I'll save more money, gain more by working a few shift at restaurant before I am going to grad school. However I am willing to spend more (as compare to just visit Toronto) as it is within my travel budget for 7-10 days between those city. I also worry about time crunch for Montreal and Quebec City since I only have 4-5 days for both (which is reasonable enough for first time visit upon my research but still want to hear y'all thoughts since I cann't make decision).

My other chances to visit Canada again are very small, at least 4 years from now and even more and then by then it might be with family, thus maybe another pros for doingg all now is have experiences for future use with family. Or it doesn't matter because in a decade from now, things will change a lot lol
