David, some of your information concerning the 1st Canadian Infantry Brigade is not correct. The Brigade did not come over to the UK in one lift as you seem to indicate. Elements of the Brigade were assembled at Val Cartier, The RCR and the Toronto Scottish were part of this group, and they sailed and arrived on the dates that you mentioned. A second group, the 48th Highlanders and others left Canada about a week later and arrived at Greenock New Years Eve 1939. The Toronto Scottish used brag about playing the 48th into Corunna Baracks. I have not checked the other movements that you mentioned up until 1943.
In April 1943 the 1st Brigade, the infantry units at least, traveled to Inverary Scotland to train for the invasion of Sicily. A and B Coys of the RCR shared Auchinleck Barracks with the 48th the rest of the units were billeted out.
There were two convoys that left the UK for Sicily they were known as the Fast and Slow convoys. The Fast convoy carried the Infantry units and left from Gourock Scotland on the 28th of June 1943.
The Slow convoy left from Liverpool I believe and carried the Transport and Artillery.
