We have been card carrying members of Toronto zoo for years. If you plan to go more than once and with family it is well worth it. With membership you don't have to kill yourself trying to walk the whole zoo because of multiple trips. Animals seem more active in the cooler weather. Pro tip: if you get the membership pay extra to get parking included; you will save big throughout the year.
Confession time. My son is in summer school and had to be up early for a test today......I left at the end of the 8th and didn't see the walkoff live. I know, shameful...have to redeem myself some way before the season ends.
