From Library & Archives Canada;
Census numbers allotted to Canadian Forces to 20 Oct 1942
CT28841 to 29140 - Carriers
CT42809 to 43651 - Carriers
CT59184 to 59683 - Carriers
CT39781 to 40980 - Ram tanks
I haven't found a later allotment but I continue to search, although it is more in hope than in anticipation.
