4th Canadian Division would mean a Gold maple leaf over a green background.

"76" would be on a square with top half in red, lower half in blue.

"TLD" (Troop leader of D troop) would be on a blue and red square. From what I read on the web, 36th Battery was the second battery in the 23rd Field regiment. This would mean that "TLD" would be on a blue square, with a smaller red square in the lower right corner.
The TLD tactical sign also appears on the sides of the vehicle.
