In Ontario, as of March 1st, (and in Manitoba as of March 15th) vaccine QR Codes are no longer required by the province. JAM will only enforce proof of vaccination if it is a requirement by a particular venue. Some venues will still ask that all participants show their QR Code before entering the facility after the mandate is lifted by the government. Please be sure to read all league notes carefully to see if the league you are registering for requires you to be fully vaccinated.
