'Beat the Clock' - but only for Canadians winners

Factual Questions
1

I have an entry form for a contest (one year free membership to a Bally Total Fitness health club - I had picked it up while waiting for my lunch). Quoting from the rules on the back:

8. <snip> …Canadian residents whose entry forms are drawn must successfully complete a timed skill testing question in order to receive the prize.

This is not the first time I’ve seen this sort of requirement. No other countries are mentioned, nor is there the soloist ‘Void in Québec’.

Is this a U.S. or Canadian requirement for contests? What is its purpose?

If any Canadians have won, what sort of questions are involved and what time limits? And what the heck is a “skill testing question”?

[Side note - I wrote to the PR Department of the company (quite some time ago) and have yet to receive an answer.]

Guess: Pure lotteries are illegal in Canada but “games of skill” are not. The timed skill test is probably easy enough that anyone could pass it and is just a formality.

Lotteries are not illegal in Canada-- They can be run
by government agencies and native groups.

“Raffles”, (with non-cash prizes,) are legal for fund-raising for non-profit organizations.

Similar schemes, (eg “scratch & win” promotions for commercial outfits,) must meet the “game of skill” requirement. Usually, these are simple (single-digit) arithmetic questions. If anybody ever slipped up on one, the embarassment would last far, far longer than the disappointment of missing out on a free cheeseburger. I doubt that this has ever happened, though.

(5 + 2) - 4? … Can you give me a hint?
