A group representing frustrated Tim Hortons franchisees says its board members have been accused by the company of helping leak confidential information.

The Great White North Franchisee Association says its board members have been served with notices of default.

In a letter to the company posted on the association website, association president David Hughes denies the allegations and accuses the company of trying to intimidate and interfere with its rights.

Tim Hortons did not immediately return a request for comment.

The franchisee association was formed in March amid complaints by members that the parent company was using its power to extract more profit from franchisees.

Tim Hortons has said that the company is focused on working with its elected franchisee advisory board.
