The polymer notes work quite well in Canada.
The only thing I don’t like about them is that our liberal government uses the images on the cash to propagandize and not teach Canadian history.
Are older paper dollars still good?
We visited Canada a few years ago and so my dad gave us his left-over Canadian cash from fishing trips in the ‘80s. We didn’t know there had been a change and people took 2nd looks at our funny money.
One cashier said, “Got it from under the mattress, eh?”
No one refused it.
Side note ... DD’s college roommate was from Canada and told her the polymer notes were scratch and sniff and should smell like maple syrup. But they didn’t. DD told our cousins this and they almost fell out of their chairs laughing.
