Just head to the great cities. Especially Toronto and Montreal, which seem to be vying with each other for the title of Liveliest City North of the Border. Both cities explode with fireworks in summer. Both cities are jazzy, but Montreal really swings. The city's International Jazz Festival from July 1-12 draws musicians from throughout the world and has become one of North America's top events.
Many performances are free and all are downtown.
In Toronto, there's the duMaurier Jazz Festival, June 19-28. Almost half of Ontario's citizens report an ethnic background other than English or French. Toronto has become so cosmopolitan that it has become a major motion picture center, with its streets and buildings doubling for places around the world. The trail, now open, links five destinations and 12 interpretation centers. At L'Anse aux Meadows National Historic Site, visitors can interact with Viking personalities and learn of the Vikings' technology.
