I'm glad I took a look at the weather app before traveling to Montreal! I knew up there is never quite hot not even during the summer but to the point of having to bring actual outwear to be comfortable outdoors without having to run back to the hotel because you are freezing, specially at night. I had a few inconveniences before my trip (the result of not traveling with the right people) and that didn't allowed me to pack the right clothes... hiking in leather pants eee not such a good idea but I made it through and enjoyed my chic outdoors adventure.
