All buses are cancelled again today for the Upper Canada District School Board and the Catholic District School Board of Eastern Ontario.
Student Transportation of Eastern Ontario made the call after freezing rain covered area roads with sheets of ice overnight.
Now a freezing drizzle advisory has been put in place by Environment Canada for the area.
Scattered patches of freezing drizzle will continue this morning from overnight, but will transition into scattered showers as the day warms this afternoon.
Environment Canada says freezing drizzle can produce thin, hard to detect layers of ice and warns for slippery roads and sidewalks.
