maybe during peak covid? but certainly not now. this comment is either being intentionally disingenuous or just parroting a random article from an extraordinary (and no longer applicable) time of our lives and presenting it as if its still the current status quo.
i am in canada for weeks at a time multiple times per year, and i have family that live in BC, AB, and ON.
cash is my primary form of payment and not once have i been turned down using cash on any of my visits. not once has family complained about being unable to use cash (several of the older of them, like me, primarily use cash).
