I wrote a letter to BMW Canada, and both dealers.
The local dealer agreed to address the issue by using the Road-Force balancing unit to fix the vibration and if necessary, replace the tire if it is defective. It was the outcome I was looking for but unfortunately I had to put pen to paper (the old fashioned way) to convince BMW to do the right thing.
The work hasn't been done yet as the dealership is waiting for a part related to another issue.
EDIT: got home from work to find a message from the dealer... going in next Monday.
