I received the paint chip sheet from Ken McGee, "General Motors of Canada Ltd 1948 standard colours". This sheet provided GM codes as well as codes for Opex O-K Lacquer and Fleet-X Spraying Enamel. For future Canadian colour postings here is what is on it:
Commercial Green Code 832
Commercial Maroon Code 833
Commercial Oshawa Blue Code 834
Commercial cream Code 835
Commercial Blue Code 830
These "Commercial" colours seem to also be on a 1941 sheet.
