Though the rules don't mention the Regie of Quebec, I'd say that Quebec residents cannot enter the contest. It's this section:
1. Eligibility: Sweepstakes (the "Sweepstakes") is open only to those who sign up at the online sweepstakes page and who are at least 18+ years old at the time of entry. The Sweepstakes is open to the legal residents of Canada and is void where prohibited by law. Employees of ECS Coffee (the "Sponsor") their respective affiliates, subsidiaries, advertising and promotion agencies, suppliers and their immediate family members and/or those living in the same household of each are not eligible to participate in the Sweepstakes. The Sweepstakes is subject to all applicable federal, state and local laws and regulations. Void where prohibited.
As the prizes are over $100 each in value, that means the Regie would need their fees and the rules don't state anything about paying the Regie. YMMV>

The prizes:
5. Prizes: The retail value of the first prize, DeLonghi Specialista Espresso Machine is $899.99. The retail value of the second prize, DeLonghi Dedica Espresso Machine, is $379.99. You are not guaranteed to win a prize and your chance of winning is dependent on the total number of eligible entries received. Actual/appraised value may differ at time of prize award. The specifics of the prize shall be solely determined by the Sponsor. No cash or other prize substitution permitted except at Sponsor's discretion. The prize is nontransferable. Any and all prize related expenses, including without limitation any and all federal and local taxes shall be the sole responsibility of the winner. No substitution of prize or transfer/assignment of prize to others or request for the cash equivalent by winners is permitted. Acceptance of prize constitutes permission for ECS Coffee to use winner's name, likeness, and entry for purposes of advertising and trade without further compensation, unless prohibited by law.
