I can't help with the Canadian paint codes and don't know what color Red Chevrolet Canada used in '41.
My first question is, did Chevrolet Canada build the fire body or was the bare Cab and Chassis shipped out to a vendor and up-fitted? If they sent it to a vendor, then they would have painter the entire truck their shade of red, so the entire truck matched. That's the way my '57 was done...Cab and Chassis was bought in Cardinal Red, then shipped to John Bean to have the fire service body installed and then they painted the truck and body in the shade red the VFD requested. My fire wall is still Cardinal Red while the rest of the truck is a Dark Red that's almost Maroon in color. I don't know if they built them that way for WWII in 1941...
