1 Week Quebec city, Montreal & Ottawa trip!

Hey everyone

I’m a uni student from Toronto and during my reading week in feb ill take a budget trip to Quebec city & montreal, I was thinking of adding Ottawa for a day too but not sure

I wanted to know how many days you would recommend spending in each city, i was thinking 2 days in Quebec city, 3-4 days in montreal (i’ll be staying with a friend so no hotel/hostels) and perhaps 1 day in Ottawa?

I’d also love to know your recommendations for MUST see places in each city, or just any other generic advice you may have for someone who’s traveling solo through multiple cities for the first time

thank you!
