Jason,
While the image quality is poor, here is a link to another Stuart picture that was apparently taken on 24 Aug 1948, after a mishap in Alliston. (The first town south of Borden for anyone unfamiliar with the area).

Page nine of this same newspaper edition also has an image of the MND observing an exercise from a Grizzly APC (“Kangaroo”).
The book linked in my first reply has an image and date which purports to be the dedication of the RCAC Memorial. However, I am skeptical about some of the image captions in the book, especially those with 1940s and 1950s dates.
This LAC entry indicates the Memorial was under construction in Autumn 1948:
