This is the French variation of the anodized (or ‘Staybrite’) King’s Crown “Pénitenciers Canada” badge.  Since this badge was only issued to the nine federal penitentiaries in the province of Québec, it is somewhat scarcer than the English “Penitentiaries Canada” version. “Made in England” is debossed on reverse of the maple leaf (likely J.R. Gaunt, London)
