Yes.
Columbia Records Canada, had their own pressing plant and issued/pressed quad discs just as in the U.S.A.
They had no gold label as in the U.S. just what you see as the white, red grey label and later SQ discs with red letter and grey, but discontinued pressing SQ dual inventory in late 75 early 76, and started to carry imports (American) after that.
Two of the last SQ quads pressed I know of were PINK FLOYD-WISH YOU WERE HERE and JEFF BECK-BLOW BY BLOW.
Yes the jackets were printed in Canada.
Thank you my fizzy friend, you are a mine of information and a multichannel mensch :upthumb
