Where are the homestay families from? Are they all Canadian.
All homestay families are Canadian. However, not all Canadians are Caucasian. Canada is an immigrant country and Toronto is the most ethnically diversified city the world. This means that your Canadian homestay may be originally from somewhere else, another country.
All homestays however must always speak in English in the house, have lived in Canada for at least 6 years and speak English proficiently.
