I guess that I will wade in on this also. It was mentioned in an earlier post that the 'claw back' is due to the US ITAR (International Trafficking in Arms Regulations). Anybody who runs a military museum in Canada should be well aware of the effects this US Law has had on the private ownership of military goods in Canada. Under pressure from the US State Dept the Government of Canada amended the Defence Production Act by adding a section on Controlled Goods. These goods, to further confuse things, are listed in the Export and Import Permits Act list of goods controlled for export from Canada.
I don't think that DND gives a rat's ass about MilVeh collectors but their ITAR compliance office probably had a bird when they heard that the US-manufactured military goods had been loaned by the CWM to a third-party. If the affected museum really wants to have the M113, etc.., back they should apply for an export perrmit from the US State Department (Yes, I know, the goods are already in Canada, but that's the way these things work.) If 'State' approves the 'export' then the CWM can return the vehicles to the borrowing museum.
The above is the result of 6 1/2 years at Foreign Affairs dealing with these issues. You might not like the answer and we will all agree that it makes no sense, but that is the way it is.
