This is a photo of what is claimed to be the very first Tim Horton's in North Bay, Canada. It's rumored that this restaurant, started by Tim Horton and his brother, did not serve coffee or donuts, just burgers. Is this fact or fiction?

All the research I've found says what wikipedia says:

The chain's first store opened on May 17, 1964, in Hamilton, Ontario, under the name "Tim Horton Donuts"; the name was later abbreviated to "Tim Horton's" and then changed to "Tim Hortons" without the possessive apostrophe. The business was founded by Miles G."Tim" Horton, who played in the National Hockey League from 1949 until his death in a traffic collision in 1974.

This is what I've thought since I was a kid. I figured they used the power of Tim's name to give this business a shot and it was a success. But according to the CBC Hamilton:

CBC Morning North's Markus Schwabe says this about Tim Horton: "His first restaurant was not in Hamilton but in North Bay. It opened on Lakeshore Drive in the early '60's and it sold hamburgers not donuts."
