We are heading to a wedding in London but flying in and out of Toronto. We're thinking of spending a few days in TO...probably downtown but we will have a car.

What fun things are there to do with a toddler (2.5)? I was thinking either the Zoo (I'm not really a zoo fan but I hear it's a nice one), Ontario Science Centre and/or CN tower... I've been to the city a few times but never with a toddler in tow. Anything in particular she would enjoy?

Thanks!
