No 1945 dated ones in my collection either; just 1940 to 1944. But here's an oddity from my collection; 1941 dated with "PETROLEUM SPIRIT HIGHLY INFLAMMABLE" embossed in the top. Question: when did the Canadian manufacturers stop putting that warning on top of the 2 gallon cans? I thought it was 1940, but this suggests otherwise?

Paint is non-original, BTW.
Thanks!
Owen.
