Snowfall rates forecast to exceed 1 cm an hour across the Greater Toronto Area (GTA) by 6 a.m., ill-timed for a treacherous and slow commute.

By Monday afternoon, snowfall eases as the system slides eastward, while portions of eastern Ontario are still dealing with lingering, light snowfall. By Monday evening, just light flurries will remain across the area.
