I bought S21 ultra, the Canadian model from Amazon. The same cannot do the monitor saying not supported in your location. It failed to connect with Samsung watch 3 and now the Samsung 4 classic watch. I live in the USA
As your product is a non-US model and the support for these models is very limited, please seek a support team in Canada. You can do so by using this link here: https://www.samsung.com/us/common/visitlocationsite.html. They will be able to provide further assistance regarding your concerns.
