Criticism of Canada Day grows in the wake of unmarked graves found at old residential schools

Canada Day is usually a day of celebration. Flags are flown, fireworks launched and the anthem sung.

But in the wake of hundreds of unmarked graves being discovered at residential schools in B.C. and Saskatchewan, a movement to "cancel Canada Day" is growing.

Several First Nations and municipalities in B.C. are opting not to mark the occasion at all.
