Seventeen cases of measles have been confirmed in Quebec, Ontario, Saskatchewan and British Columbia — more than half of those in the Montreal area, while one Ontario case has been linked to a high school.
Quebec public health director Dr. Luc Boileau confirmed 10 cases on Monday, almost all of them involving children and making Montreal the country’s epicentre. He said only three of the cases were linked to travel outside of the country, indicating community spread in and around the city.
