The Duke and Duchess of Cambridge, as they are officially known, visited Quebec City on Sunday, where they took part in a prayer service and met with residents of a homeless youth center.
The royal newlyweds encountered small but vocal protests for the second straight day during their visit to predominantly French-speaking Quebec. They began their Canadian trip in the largely English-speaking capital, Ottawa, where they were cheered by tens of thousands of people on Friday's Canada Day holiday.
The couple also honored a Canadian military unit at City Hall.
The prince spoke to the crowd in French and got a few laughs after apologizing for his accent. The couple also surprised the crowd by chatting and shaking hands with enthusiastic supporters.
Sunday marks day four of their nine-day trip in Canada.
They arrive in Los Angeles on Friday.
