It has since been revealed that one of two brothers wanted over the mass stabbing has been found dead. Damien Sanderson was found on Monday in the remote indigenous community of James Smith Cree Nation where many of the victims lived. The motives behind the deaths remain unknown.
Canada holds a special place in Prince William and Kate's hearts. They travelled there on their first joint trip in 2011. It was also their first royal tour as newlyweds, since they'd gotten married just a few months earlier.
"Canada has far surpassed all that we were promised," the Duke of Cambridge said. Five years later, the Cambridges kept their promise and returned to Canada with Prince George and Princess Charlotte, their two eldest children.
