Adopting a cat in Montréal

In your experiences, what are some considerations to keep in mind before adopting a cat in Montréal? I'm new to the city and to pet ownership in general, this would actually be my first pet. But I'm pretty familiar with cats from my parents having them most of the years.

Things like insurance, where to adopt here, how much to budget for, and other more Montréal-specific considerations are what I’m mostly looking for. This is new territory, so I appreciate your advice!
