Michael;
Some other sources of information that came to mind:
From DHH:
CMHQ Report No. 132 - Canadian Operations in Sicily, Jul-Aug 1943, Part III: The Story of 1 Cdn Army Tk Bde
CMHQ Report No. 158 - Operations of the 1st Canadian Armoured Brigade in Italy, May 1944 to February 1945, Part I: The Gustav and Hitler Lines
CMHQ Report No. 160 - Operations of the 1st Canadian Armoured Brigade in Italy, May 1944 to February 1945, Part II: The Advance to Florence, 3 Jun - 1 Sep 44
CMHQ Report No. 165 - Operations of 1 Cdn Inf Div and 1 Cdn Armd Bde in Italy - 25 Nov 43 - 4 Jan 44
CMHQ Report No. 175 - Operations of the 1st Canadian Armoured Brigade in Italy, May 1944 to February 1945, Part III: The Gothic Line
CMHQ Reprt No. 181 - OPERATION GOLDFLAKE - the move of 1 Cdn Corps from Italy to North-West Europe, Feb-Mar 1945.
There are more CMHQ Reports dealing with Sicily, Italy and NWE, but the above are the ones I can think of in relation to your subject. Also a source of information are the various AHQ Reports dealing with Sicily/Italy/NWE, also available from DHH.
Another source of information, is the book:
DRAGONS OF STEEL, Canadian Armour in Two World Wars by John F. Wallace, MC, published in 1995, ISBN 1-896182-04-0, and of course, the 3 Volumes of the Official History of the Canadian Army in the Second World War (which were written in part, from the information from both CMHQ and AHQ Reports).
