Environment Canada says there may be “reduced visibility” at times this morning in heavy snow.

“Although modest snowfall amounts are expected, the timing of this snow will be problematic. Because the holiday season is now behind us, and traffic patterns should be closer to normal, this snow is expected to have more of an impact on the morning commute,” the weather advisory read.
“Travel will likely be challenging. Roads and walkways will likely be difficult to navigate due to accumulating snow. There may be a significant impact on rush hour traffic. Visibility will likely be reduced at times. Allow extra time for travel.”
Snow is expected to taper off this afternoon but could transition to freezing drizzle, Environment Canada said.
Toronto is expected to see a high of 1 C but it will feel like -12 in the morning.
