::: Let's step back a moment.  
 ::::Caen was a D-Day objective for the *British* 3rd Infantry Division. They didn't even attack the city on June 6 - they halted before they got there. HJ wasn't even committed to combat on June 6. So in the initial attempt, the records of neither the Canadians nor the HJ are relevant.  
 ::::The second serious attempt to take Caen was by the *British* 7th AD in the Caumont gap / Villers-Bocage debacle. Again the HJ had no role in that fighting. 
 :::: It is plain silly to argue that somehow the supermen of the HJ kept anyone out of Caen. Caen and Cherbourg were the focus of pretty much the whole allied effort in Normandy in the early stages (Cherbourg till June 27 and Caen till July 18-20). To claim that one division kept an Army Group main effort from succeeding is an extraordinary claim that would require extraordinary evidence. We don't have that here and we won't get it, because most of the historians won't back the claim. The HJ played their role as part of a much larger force, as did the Canadian 3rd ID. Let's not over-state what the sources say.
