There is no adapter with the standard folding stock. The folding mechanism is part of the stock and bolts straight up to the receiver.
You will need an adapter to mount an ace folder. The issue will be finding a Ace stock in Canada. Folding adapter can be purchased from a company in the states who sells them to Canadian.
If memory serves me correctly, the folding mechanism adds length and a shorter Ace stock is required to maintain the correct pull length.
Went through this process over a year ago. Ended up purchasing a CZ factory over-molded folding stock for less than the price of fitting an Ace Stock (if you can find one).
