District Fire Chief Gerry Morris tells CHSJ News readings inside nearby buildings including the CIBC bank failed to turn up any traces of natural gas.
Morris says there were roofers working on one of the buildings and it appears some of the fumes from propane fired heaters may have been hauled in through the ventilation system.
After double checking for gas fumes - the o-k was given a few minutes later and life returned to normal at the busy intersection.
