The government says in a news release that the code-- which can be downloaded or printed - replaces the COVID-19 vaccination record that was made available in August but did not include a digital format.
The province announced last week that proof of vaccination will be required at non-essential businesses - including restaurants, casinos, movie theatres and indoor sports venues - beginning Oct. 1.
It won't be required for civil services, retail or grocery stores, places of worship, hotels or at non-ticketed amateur sporting events.
Businesses can verify the QR codes on mobile devices using a special app.
The news release says travellers at international borders will also be able to use the code
