Some sweepstakes exclude Quebec residents because the Regie Des Courses Et Des Lotteries imposes strict restrictions. ( Vermont also does it too to a much lesser extent). For any prize over $99 the sweepstakes must put up a bond, agree to settle any disputes in Quebec and pay a fee of 5-10% of the value of the total prizes given out before getting a permit, and must not make any purchase a condition of getting entered in the contest. The government in Quebec makes a lot of money with it' s lotteries and does not want any competition, so a lot of companies choose not to offer Quebec residents the chance.
