Canadian health officials have confirmed 15 more mild cases of swine flu, raising the country's total to 34. Dr. David Butler Jones, Canada's chief public health officer, said Thursday that Montreal has reported its first case. There are also five new cases in British Columbia, four in Alberta, four in Nova Scotia, one in Ontario. The four new cases in Nova Scotia are related to four previous ones after an outbreak among students at a private boarding school in Windsor who returned from a trip to Mexico earlier this month. They have since recovered and have returned to school.
