Tim Hortons is doing their part:
Alberta Rose Donut
Rallying to support relief efforts, local restaurant owners have created a special Alberta Rose donut, with 100 per cent of sales from the $1 baked good going directly to Red Cross flood relief efforts. The Alberta Rose is a vanilla dipped, bloom donut with a venetian cream center, topped with strawberry bark. Available for a limited time at participating Alberta restaurants. Canadians wishing to help can also text "FLOOD" to 45678 to donate $5 with all proceeds going to the recovery, restoration and rebuilding of Southern Alberta.
This is at the Canadian shops. I don't know if they have it at the U.S. ones too. (I should stop by one of the Ann Arbor ones and check that out.)
I just did a Google search for others. Here are a couple:
