GM Foxes in N.West Europe

[James Gosling]

Whilst surfing the Web ,I came across 'Report NO 141,The Situation of Canadian Military Forces Overseas'. On one of its pages there is a request by 21st army for all surplus foxes in the UK to be retained for internal security in North West Europe. It then goes on to confirm that the canadian army went on to hold 200 for this purpose.
Has anyone any information about this ,were they ever used and if so which units received them ?
