Yes. Canada can be very, very cold in the winter time. It reaches up to -50 degrees celcius in some parts. One of the main reasons why I moved to El Salvador. I don't like the cold.
In summer time it gets pretty hot too.
There is no very much social life in Canada, but that's my opinion, because other people just love to go out and might have a different opinion. But as for my experience, people are just too busy working and no time for friends and family. And that is also one one the reasons why we moved.
