Assuming you mean this Thanksgiving, if your points are 2019 points, and you cancel before your banking deadline (July 31), you can bank them.
If they are points that were banked into your 2019 UY (2018 points) of borrowed from your 2020 uy into 2019, then they do expire on 11/30, so cancelling gives you until them to use them or rent them.
So the answer depends on what UY points they are, and when you cancel.
If you cancel Aug 1 or later, then yes, you have until 11/30 to use them or lose them, regarless of the points original UY.
My guess is you would be able to rent that out successfully should that happen.
