This is what was announced on CTV in Montreal. Québec has been working on a vaccine passport for a while. Interesting about "scarf and neck warmer" being acceptable.
A vaccination passport will not be required for outdoor winter sports and activities such as cross-country skiing, hockey, though participants must be able to keep one metre apart, and masks will be required in indoor facilities, like chalets and cabins. A vaccination passport and mask will be required to access catering areas and bars."
