The first place to look is on www.12rbc.ca - that is the site of the Regimental Association. The Association has recently published a book called the Chronicles of the Three Rivers Regiment (Tank), detailing the activities of the unit from the time it was called to active duty, through the Italian and European campaigns, until their return to Canada. You can find details on ordering the book on the website.
If you live near Trois-Rivières, the Association is holding a get-together week-end with the veterans on the week-end of 20 - 22 Oct 06. According to the President of the Veterans' Association, there are 86 veterans on his mailing list. We are hoping to have a dozen or so attend the ceremonies.
Hope this helps,
