Planning a summer trip

After a long day, here I am trying to write something. well, I am going to Canada this summer, and I was looking for places to visit. My sister's boyfriend is canadian, and he will be our guide in the trip. He said we should go to the Niagara Falls for the beautiful view. Then, we are going to the National Zoo of Canada in Montreal. After, we are going to water museum in Toronto. We are still looking, but I believe it is going to be an awesome, and unforgivable trip for us.
