I think the coins with King Charles on them were starting to appear in Canada late last year, and I never saw any in Newfoundland to this day. I gave up doing in-person teller service since July 2012 due to my full-time job and lack of faith for new prefixes seven months into 2022.
I am thinking the banks in my hometown only ordered a coin supply for several months only a few times per year, and maybe nowadays they only do one big order once a year - typically in April, or the week prior to Easter - usually after the snowy weather is over and the ferries can go through more frequently. If they only order one big supply of money for the year ahead, it's probably due to much higher shipping costs especially since they may have to be sent in via the Marine Atlantic ferry (and Marine Atlantic rates are insanely high now, and rates tend to rise every April 1 - how much further can they go?), and travel over 800 kilometres from Port aux Basques to many of the major municipalities.
