Premier of Alberta Rachel Notley, Mayor of Edmonton Don Iveson and Mayor of Calgary Naheed Nenshi, whose collective surname initials make up NIN, have been using the group's logo with their names Notley Iveson Nenshi and the slogan, Building Alberta Together, on T-shirts.

However, the trio has reportedly received a letter to stop using the shirts because of "infringement."

Iveson says, "We got advice that there were some concerns about the trademark and essentially to cease and desist."
