What to do to have a Great family weekend in Ontario?

Question

We live in Barrie and would like to do something special for our kids on the long weekend June 27th to the 30th. Would anyone have an suggestions or can recommend somewhere and something to do? We though Midieval Times or Niagara Falls, but we've already done these. thanks everyone

Answer 1

How about Marineland, any Niagara Falls indoor waterpark (I think there's three now), Clifton Hill, a Blue Jays game (that Saturday is a "Jr. Jays Saturday" with additional kid attractions and they can run the bases after the game) or Canada's Wonderland?

Answer 2

If they like animals, check out the Toronto Zoo... or African Lion Safari.  

There is also Centreville, on Toronto's Centre Island.  

The Science Centre in Toronto is cool too.
