On January 17, 2022, a record snowfall hit the Toronto area. Yes, this is Canada, and it does snow here, although people who live in areas without the moderating effect of Lake Ontario rarely have much sympathy on that score.

A post mortem report on the event will be discussed on March 29, 2022, at the Infrastructure & Environment Committee. As the City’s report on the event summarizes:

On January 16-17, 2022, the City of Toronto experienced an extraordinary winter storm that involved extreme cold temperatures, very rapid snowfall, and an ultimate snow accumulation of 55 centimetres in just 15 hours. The below freezing temperatures that followed the storm and lasted for more than two weeks created a unique set of challenges for storm clean up.

The effects on transit routes were severe, and there was little or no service on parts of the network for an extended period.

Snow clearing took a very long time:

Ultimately, 179,442 tonnes of snow were removed from 3,471 km of roads, requiring almost 60,000 truckloads. Removal was conducted over a 30-day period; however, operations were suspended when additional snow events occurred, meaning snow was removed on a total of 23 non-consecutive days.

Toronto’s snow clearing practices tend to focus on major streets and often do not include physical removal of snow. This effectively narrows roads and limits their capacity until the snowbanks eventually melt. A history of warmer winters and fewer severe storms has contributed to a somewhat laissez-faire relationship to winter that failed Toronto in 2022.

The report speaks to several changes in approach to major storms that will be implemented in early 2023, and I will not go into these here beyond noting the effect on transit.

Two related problems do leap out.

First, the responsibility for various aspects of snow clearing fall to different groups. Roads and sidewalks were plowed by multiple contractors. Sidewalks were, until this year, the responsibility of property owners, but the city’s fleet of sidewalk plows was not yet at full strength, and subject to breakdowns. Bike lanes might or might not be plowed especially if they are simply painted and have no protective barriers.

The result is both a “who does what” clash and a war for space where snow can be dumped before it is carted away, if ever.

Second, the reduction in road capacity causes congestion both by taking lanes out of service, and by parked cars, to the extent motorists can navigate the snowbanks, encroaching beyond the curb lane. This is a particular problem on streetcar routes, but is not confined to them.

Plowing, when it does occur, may not be accompanied by aggressive towing, or at least by temporary relocation of parked cars so that the curb lane can be fully cleared.

Toronto has a network of designated snow routes for major snow events. Most of the territory it covers is in the old City of Toronto with some outlying areas. When a major storm condition is declared, parking is banned for 72 hours (or more if need be) on the streets shown in red below. Most of the suburban city is not included.

The map below is dated October 2013, and it is due for updating especially if Toronto plans to be serious about the quality of transit service and meaningful schemes for transit priority across the city.

In Brief

The major snowfall on January 17 disrupted transit service, and the effects continued for a few weeks after the event. In some cases, buses had not returned to “typical” pre-storm travel times into February.

The location of congestion problems on routes reviewed here was not distributed along them a a general delay, but could be found at specific locations and times where the effect was “net new” after the storm. This suggests that a detailed study of storm delays will reveal key locations and conditions that should be avoided in the future.

On Dufferin, a major location for delays was northbound to Yorkdale Mall, and this persisted for some time after the storm. Normally, problems on routes like this are assumed to arise from their hilly nature, but that was not always the case in late January.
