Marriott International's loyalty program, Marriott Rewards, is being expanded to include Delta Hotels and Resorts.
Marriott Rewards members can now earn points or miles and Elite night credits, and redeem for free night stays, at 21 Delta Hotels across Canada, with the brand's 14 remaining Canadian properties joining the program in late April.

Delta Hotels has properties in major Canadian centers of
business as well as popular tourist destinations, including its flagship
property Delta Toronto, Delta Ottawa City Centre and the Delta Grand Okanagan
Resort—all of which are now available for members to earn and redeem points.
Marriott International acquired the Delta Hotels brand in April 2015.
