An Ottawa man donated cash for the equivalent of hundreds of Tim Hortons coffees, as well as some breakfasts, making it the third identical gesture in Canada this week.

On Thursday morning, the donor gave $860 to pay for the caffeine fix of patrons at Ottawa's Trainyards location, according to the store manager.

The donation, given by an unnamed worker for OC Transpo, ran out in just over an hour, though.

This comes after a "mystery man" gave a downtown Edmonton Tim Hortons about $900 on Monday, and another person gave the same amount to a Calgary location on Wednesday.

Some thought the donation in Calgary was related to the city's flood clean-up efforts, but it is now unclear with the Good "coffee" Samaritan movement infiltrating Ontario.

Tim Hortons denies involvement in 'random acts'

In all three cases, the person was a man who wanted to remain anonymous, according to Tim Hortons employees, though the anonymity of the third man was partially broken.

There was some debate over whether these acts were hidden moves by Tim Hortons for publicity, but the company sternly denied that.

"It's definitely not Tim Horton's doing, I can assure you of that," said Michelle Robichard, spokeswoman for Tim Hortons.

Robichaud added these were three separate random acts of kindness by Good Samaritans.
