Solo travel: Montreal or Vancouver?

Hello! I am planning a long weekend in Canada in July (Thursday - Monday) and I was thinking of visiting Montreal or Vancouver.

The goal is to see a little bit of the culture and the outdoor experience Canada is famous for.

Which one would you recommend? Can I squeeze in a day for a hike?

I’d like to know what was your experience as a solo traveler in one of those cities. I know Montreal is more “French”, but is this enough to visit it?
