All municipalities in Haliburton County have declared a Significant Weather Event.
The declaration gives crews more time to clear both county and municipal roads, with efforts pausing if conditions are too hazardous. Municipal buildings are also closed.
Officials say some locations could get more than 30 centimetres of snow, and extreme weather is expected to last multiple days.
They ask residents to stay off roads and sidewalks unless absolutely necessary, and use extreme caution if you do go out.
