Transport in Canada
International airports serve all of Canada’s major cities. Ottawa, Montreal, Toronto, Vancouver, Calgary and Halifax all have international connections. The principle national airline is Air Canada, although many other carriers operate in and around Canada. There are several points at which the Canadian rail system links to the United States. Major routes run between New York-Montreal, New York-Buffalo-Niagara Falls-Toronto and Cleveland-Buffalo-Niagara Falls-Toronto. If visitors wish to arrive in Canada by sea, there are several ports that are served by international shipping lines. Cruise lines operate from Montreal and Vancouver, Canada’s busiest port. Additionally, there are ferries running along many of the Great Lakes, such as Toronto’s port on the northwestern shore of Lake Ontario. Car hire is available in all cities and from airports for full licence holders over the age of 21. However, for some hire companies, drivers may need to be at least 25 years old.
