What natural sites would you like to visit in Canada?

In Canada, a lot of attractions. I would like to start from the capital. Ottawa is full of ancient architecture and excellent museums. Visiting the city of Churchill in the north, one could see the northern lights with his own eyes. The cities of Montreal and Quebec would also not be desirable to ignore. From Canada, the entire Niagara Falls, geographically located in the United States. In Alberta County, you should definitely visit Lake Louise and Banff City with its hot springs.
