Well add me to the list. I'm 65 now but as a 12 year old kid who grew up in Toronto in a carless family, I used to hop on the streetcar and ride from my East end home to Grenadier Pond in High Park. So I guess that makes it 1958 when I would catch bullheads, small bass, sunfish and "calico bass". That pond is connected to Lake Ontario so I assume crappies have always been in the great lakes.
God Bless,
