The City of Toronto issued an extreme cold weather alert, Monday.

The alert is issued when Environment Canada predicts an overnight temperature of -15 C or lower without a wind chill.

It’s in effect until further notice.

During the alert, extra shelter spaces are added for the homeless.

TTC tokens are also available at some drop-ins centre so that people can use public transit to get to the shelters.

Street outreach is increased in the downtown core, in an effort to urge the homeless to get into a shelter.

To get an emergency shelter bed, call 311 or contact the city’s central intake line toll-free at 1-877-338 3398.

A special weather statement has also been issued for Toronto and the GTA.

Environment Canada says 10 centimeters of snow is possible near Lake Ontario overnight through Tuesday morning, which may impact the morning commute due to low visibility in heavier snow in the snow band and accumulating snow on untreated roads.

The snow is expected to end by noon on Tuesday.
