Fire crews were called to the City Market last night after it closed when the smell of natural gas was detected.
Enbridge Gas was called in and the leak was traced to the City Market's boiler room.
There was alot of smoke which could be seen from a fire in a dumpster early this morning at an overpass which is part of the One Mile Interchange project.
Fire trucks had difficulty getting to the scene and they also had to put out a small fire in a nearby construction trailer.
