The American Express Canada website made an update this morning. I suggest that you transfer today your Membership Rewards points to Starpoints.
As of August 4th, the current transfer option of Membership Rewards points to Starpoints will end. The new transfer option will be Membership Rewards points to “points” under the new Starwood Preferred Guest Program. The new transfer rate will be 1000 Membership Rewards points = 1200 points. Please visit members.marriott.com for more information regarding all of the changes to the Starwood Preferred Guest Program, including redemption rates.
The rate in that program is changing so the SPG program is ending – transferring everything to Marriott.
