Booking a refundable room to extend points

[calgarychris]

I've got 44K points in Le Club (I hate the new name) which expire next month. While I might be able to book and stay in a room locally, if Covid-19 complete lockdown doesn't prevent it I was wondering if booking a room in the future and cancelling at a later date would extend the points? Say book something in January 2021 and cancel and get the points refunded...

Anyone have any ideas how to extend these things?

Thanks
