I just contacted them as well. They said they modified their policy for International members.
But they stated that it was only until May 31, 2022. However, it only shows up the first week of your next use year. So essentially, for a Dec 1st UY, it will be posted sometime that first week. So you cannot use it to make any booking after Dec 1st until it's been "banked" there. This also means that you may not have a lot of time to use it to book....which means busy times and popular resorts may not be available by the time you can use it.
Regardless, it's still nice that they understand the challenges that we, as Canadians and international members, have with regards to using the expiring points. I hope this works out because we don't know it worked until we see it on our next UY balance.
I'm glad it's a "policy" vs a one time thing for certain members. This means that if there's any issue, it's less likely they will deny it's existence.
Thanks for posting this Canadian Girl!
