I often confuse Toronto Botanical Gardens with Edward Gardens - nonetheless, a beautiful place to have one's wedding. One of my friend's hosted their entire wedding at the TBG and during the night, there was another wedding happening as well although you could never tell. In other words, rest assured that you are getting married as if in your own private garden.
The wedding ceremony took place in a small courtyard-like area, lined with trees and shrubberies. As the sun was setting, picture perfect memories were created. Then, everyone was moved into a larger room area for dinner. FYI - We had a buffet at TBG so if you're looking to do a buffet dinner, TBG has the space and capability for that.
