Thousands of city workers are out plowing streets and sidewalks after the latest helping of the white stuff.
More than 15 centimetres of snow fell on Sunday in Montreal, followed by several millimetres of rain, much of which froze on contact with the ground.
Well-travelled streets were in fair condition before dawn Monday but sidewalks were covered in ice since crews had not been dispatched to dispense salt or abrasives.
The city of Montreal will begin a snow removal operation at 7 p.m. Monday, because while daytime highs will be above the freezing point for much of the week, overnight lows will be well below zero.
Police said that there were no major car accidents on the island as of Sunday evening.
Due to a spate of roof collapses this winter, Environment Canada also warned homeowners to clear snow from their roofs to avoid any potential damage.
