An investigation into an unusual odour that caused a Windsor apartment building to be evacuated Monday morning is ongoing.
Emergency crews responded to calls of the odd smell around 9:30 a.m. The 16th floor was evacuated, but Windsor Fire Services were unable to determine the cause of the odour.
About 20 residents were able to return to their homes after two hours.
