That sounds reasonable but I’m not certain. You could be right, especially with lumber export. Does Mexico have similar mixed units for cross border trade? Seems more likely to me Canadian sizes are the way they are because of the Imperial system and commonwealth history. The US never used the Imperial system so even when both countries used gallons they were different sizes.
