Ontario, one of the ten provinces of Canada, is home to the nation's capital city, Ottawa, and the nation's most populous city, Toronto. Bordered to the south by the US states, it is Canada's most populous province by a large margin and the wealthiest. Ontario has the best grandstand view of the Niagara Falls – to the chagrin of many tour operators in the US. Ontario is also host to two longstanding theatre festivals, with its emphasis on the works of Shakespeare.
