I went here in april, it was very cold for the time of year, the first day i arrived i was walking outside and my face started to get numb with cold i could hardly talk, if i were you i would leave visiting until the summer, i was told it’s buzzing in the summer, if you dont like the cold like me you could actualy get a train into montreal stay for week’s, and never set foot outside, it has over 18miles of underground system including; shop’s cinema’s restraunt’s opera house, i think even a church, dont leave without seeing old montreal it’s the most beautiful of the city
