I loveeeeeee the Toronto Zoo!
The last time I went was in 2008 and there was so much that was different!
I went with four people, 2 adults and 2 kids + parking + zoomobile pass, which came up to $130. This doesn't include food but there were lots of people that brought food and ate at the picnic areas.
I would definitely recommend the family membership if you live in the area and have young ones that likes animals ($195)
They have a special panda exhibit until 2018 and part of the zoo is under construction but if you are on the zoomobile you get a sneak peek!
Enjoy!
