Snowfall and icy roads caused numerous accidents on Toronto-area highways during the morning commute, including a 15-vehicle pileup on Highway 401 in Brantford.

No one was seriously injured in the massive pileup, but police were urging motorists to avoid the area because of the icy conditions.

Snow blowing off Lake Huron and Georgian Bay caused travel problems on roads in the traditional snow belt areas.

Some areas were expected to see up to 15 centimetres of the white stuff.

Closer to Toronto, ice on Highway 400 south of King Road caused a transport truck to spin out in the southbound lanes.

There were traffic tie-ups on Highway 401 at Yonge Street when the two left lanes of the westbound express lanes were closed for emergency repairs.

Weather was not to blame for that delay, however. Repairs were needed because a piece of metal dislodged from an expansion gap in the road.

The problem damaged five trucks overnight, causing blown tires, severed fuel lines and ruptured diesel tanks.

No injuries were reported.
