Matt, can I ask how old you were when you moved to Montreal? Were you a metro enthusiast from a young age?
I ask because I’ve been a rail enthusiast since about the time I could walk, and much of my early travelling alone on Sydney’s trains was of my own volition and just for the sake of riding the trains. Was there a young matt out there on the metro for the joy of it?

I was 13 when I moved to Montreal, and yes, I was instantly fascinated by the metro, never having lived in a city with a metro before (I grew up in Winnipeg). Within a few months, I had memorized all the names of the metro stations and had a collection of a transfer from each station.
Also, I was born on the 15th anniversary of its opening, of parents who met on the 80 Av. du Parc bus 
BTW, other people asked about shopping. Most of the stores I need for my daily stuff - grocery, drugstore, post office, café, tea shop, etc. - are within walking distance (actually along the commercial street between here and the metro station). In the old neighbourhood, where the grocery store was farther away, I used to have things delivered when I did a big shopping run.
For other things I just go downtown and shop there. (Montreal has a very vigorous, well-used, safe downtown area, with several malls as well as scads of small businesses of every kind.)
Montreal has big box stores, but by and large they’re in the suburbs, and I rarely ever need anything they sell. Many of them have smaller outlets downtown (Canadian Tire, the Bay, Bureau en Gros [Staples], etc.). Pretty much the only big box store I ever go to is IKEA, and then I make a day of it and go with a friend who can drive; we take their car or rent a truck there. I used delivery when I moved in, and when I was a poor student I used to carry truly awesome quantities of furniture home by myself by bus and metro.
