Most of this strip (if not all) was shot by a Canadian cameraman

Some of it (2:06 to 2:46) is Cagny but I am more interested in the location of the staged scenes around the pak 88 (1:36 to 2:02)
There is also a still of the same location widely available around the net that claims it was taken on 18/7/44 but I doubt it is anything more than a guess. It must be a Canadian photo but it is never identified by number nor have I seen it in any publication

What I would like to know is there a list of the holdings of Canadian WW2 films. I have a copy of the WW2 IWM Normandy list so I know it is not in the UK collection. I am hoping there is a Canadian 'master list'.
