Toronto is a city in Canada, and Canada was originally a British colony. As a result, Toronto has inherited many British traditions and customs. For example, the official language of Toronto is English, and the legal system is based on British common law. Additionally, many of Toronto's institutions, such as the University of Toronto and the Toronto Stock Exchange, were founded by British immigrants.
While there is also some French influence in Toronto, it is not as significant as the British influence. This is due in part to the fact that Canada is a bilingual country, and French is only one of the two official languages. Additionally, the French-speaking population of Toronto is relatively small compared to the English-speaking population.
