Several craft fairs that were held around Christmas time have instead been moved to the fall (Puces POP) and others have been postponed to 2023 (Souk) but there are still some you can visit:

• Salon des métiers d'art (December 8-18): the fair is being held this year at the Olympic Stadium rather than Place Bonaventure, which had been the case for several decades,
• Grand Marché de Noël de Montréal (until December 31): at the Place des festivals (Montreal's downtown, Place-des-Arts metro station),
• Marché de Noël de L'Assomption (until December 23),
• Marché de Noël et des traditions de Longueuil (until December 18).

You can still buy your products made in Quebec online, but don't wait too long, delivery services will be overcharged.
