Did you Know About Milk Tokens?

Found at an Etsy shop with this information:

From the late 19th century through the 1960s and 1970s, dairy distributors of Canada issued tokens as monetary substitutes for convenient home delivery. They also served as advertising.

Kemptville, I think, is now part of Barrie, Ontario. So a bit more local history for Ontario. I didn’t know there were tokens like this. But, I do remember milk still being delivered when I was a kid living in what is now the eastern edge of Scarborough, Ontario. It used to be Port Union, but not known by the name of the original town any more.
