London, Woodstock, Stratford, and Mitchell may see a slippery drive into work to start the week.
Environment Canada has issued a freezing rain warning for parts of London-Middlesex, Oxford, and Perth counties for Monday morning.
The weather agency said that freezing rain is expected to begin early in the morning and transition into snow, mixed with ice pellets, by midday.
Within those hours, between two and four millimetres of ice could accrue on roads, sidewalks, and parking lots.
Motorists and pedestrians are advised to take extra care in slippery conditions.
