With about five minutes left in the first quarter, Ford walked down the aisle behind the Atlanta bench. Fans turned from the field and took pictures. The mayor arrived just before Jackson scored a touchdown.
At least four Toronto police officers and several stadium security staff were at the entrance to the VIP section where Ford had an aisle seat. They tried to keep fans from approaching for photos and handshakes.
But Ford posed for pictures during halftime, flanked by his security minder and a pair of police officers.
While some shouted support for Ford, other yelled out insults related to his admitted drug use. When the crowd became too large, Ford was escorted to a nearby elevator.
Last month, Ford acknowledged smoking crack in a "drunken stupor" but refused to resign as mayor of Canada's largest city and financial capital. He has been largely stripped of his powers by his city council.
Ford attended a Canadian Football League playoff game at Rogers Centre last month. He is reportedly interested in going to the NHL's Winter Classic outdoor game between the Detroit Red Wings and Toronto Maple Leafs in Ann Arbor, Mich., on Jan. 1.
