And the ANSWER is?
In Canada, a company can not run a LOTTERY, that give a "prize of value". Only the government can run this kind of lottery.
What company therefore run a contest where you WIN the "right" to perticipate in a "Skill Testing" contest. You win the prize when you answer the question correct. Even at MacDonalds the game cards have a math question, but the staff will tell you the answer. It is simple a way of "following the law".
