Maurice,
I looked through the approx 1000 images that cover the turn-in of armoured vehicles from Canadian units at the end of the war.
I did find 269916, 269917, 269920, and 269921 as vehicles turned in by various units but I did not notice 269919. While your vehicle certainly fits into the right WD number block, it might not have been issued to a Canadian Unit (or could have been with a Canadian unit for a period of time, then spent time in Workshops prior to reissue to a different unit).
The records related to the turn-in start here:

Here are the links for the turn-in of 269920, and 269921:

There are other groups of records within the various 25 CADR War Diaries (Squadron and Regimental) where your vehicle might appear.
