If you have as your aim to strip the canvas away from the support, the traditional method is to adhere a piece of paper of medium weight, like an 80# cover weight, with a starch adhesive. One of the preferred adhesives is made by boiling sweet rice starch or (if you can find it) dogtooth violet starch in water to make a paste, adding a small amount of alum to harden it. A layer of that is applied to the support and to one side of the paper, adhering the glued sides together and allowing them to dry hard. The linen is then sized with bunny glue onto the paper. The bunny glue holds the linen to the paper and dries without buckling. The idea is to use enough starch to hold the paper fast and barely enough bunny glue to hold it to the paper (it's easier than it sounds because that's the way it works out. When you want to remove the linen, just slide a smooth bladed knife or spatula under the linen and the paper will stick to the board and the linen can be gently coaxed up from the paper, bringing very little paper with it.
