The market is a must see in Toronto. Although, it is a must see only once. It is an awesome thing to do on an evening with some friends or just as a date!
The vendors are great, but obviously over priced. There are also some great food options around to nibble on as you are walking around. The big massive tree is beautiful and an amazing place to take a great photo.
The distillery district is a fantastic place to be at all times. If you haven't been, go. During the Christmas season it adds that extra touch.
Just beautiful.
