Thanks nanut for confirming that this coupon is still valid!
Use printable Toronto Zoo coupon to get free child admission. That is $12 in savings. Coupon valid for one free child with one paid admission. It seems like Toronto Zoo are once again accepting this coupon. This coupon is legitimate and valid however Toronto Zoo did make a fuss about it a couple of months ago although they are the ones that released the coupon… lame
Coupon expires August 31st, 2009.
