- Travel times have increased 250% in the morning rush hour period -

The latest construction project on the Gardiner Expressway — a major transportation route which is traveled by approximately 140,000 vehicles each day — has already made an impact on driving time and emissions. A Geotab ITS study on commercial vehicle traffic on the Gardiner reveals that recent slowdowns due to construction are having an impact on business productivity in Toronto:

• Travel times on the Gardiner have increased up to 250% in the morning rush hour and 230% in the afternoon rush hour.
• Commercial drivers are spending 80% more time driving per day on the Gardiner.
• Emissions have increased 23% due to the extra driving time (an additional 1,200 kg of CO2 per day).
• The amount of traffic traveling less than 25 km/hr has doubled.
• The top three alternate roads have seen an average traffic increase of 43%.

Significant increase in travel time during commuting hours

Since construction began on March 25, 2024, commercial vehicle drivers are spending more time on the road. Travel time in some areas of the Gardiner has doubled. Geotab ITS found that the average time to travel from the Humber River to Strachan Ave. increased from 8 minutes to 20 minutes, and the typical time to travel the 5 km stretch between Jarvis St. and Dufferin St. is now 25 minutes instead of 11 minutes.

During the morning rush hour, from 7-10 am, travel times on the Gardiner increased by up to 250% on the westbound lanes, as compared to pre-construction traffic. Travel times also increased by up to 230% on the Gardiner eastbound during the afternoon rush hour. Average drive times were most impacted around 8 am, as well as the 3 pm and 4 pm commuting hours.

Slowdown adds pressure to last mile delivery

On the Gardiner, commercial vehicle drivers are spending 80% more time driving per day on average compared to the pre-construction period. The rise in travel time is impacting business productivity. The increased drive time adds pressure particularly to last mile delivery companies, which are already facing demand challenges due to the growth in e-commerce.

The Toronto Region Board of Trade reports that traffic congestion costs over $11 billion in productivity losses each year, and impacts trade and productivity in the city. In 2023, there were 19 million annual commercial trips in the Toronto Core, representing 151 million kilometers driven.

Geotab's recent State of Commercial Transportation examined overall productivity and looked at both the average number of trips per day, average driving duration per day and trip to hours ratio as proxies for gained (or lost) productivity by fleets. In this context, we see that commercial fleets have experienced decreased productivity due to the Gardiner closure. For commercial fleets, in addition to the potential impact to service, spending more time in traffic can add up in fuel costs. For every hour of idling, an engine wastes 3 litres of fuel.

Vehicle emissions increased

Longer drive times on the Gardiner are increasing CO2 emissions from commercial vehicles. Increased driving time led to a 23% increase in emissions, equating to approximately an extra 1,200 kg of CO2 daily from the vehicles in the study — the same as the carbon footprint of a premium roundtrip flight from Toronto to Vancouver. As well, Geotab ITS identified a 26% increase in commercial vehicle idling time.

Traffic-related air pollution (TRAP) from cars, trucks and other vehicles is the largest source of air pollution in Toronto. Air pollution can have a negative impact on health and has been linked to respiratory and cardiovascular diseases and cancer, and increased levels of air pollution from traffic reaches up to 250 meters from a major road.

Traffic shifts to secondary roads

Other Toronto roadways have seen increased commercial traffic as drivers seek alternative routes. The top three roads most impacted by commercial traffic congestion, with an average increase of 43%, are:

• Harbour St. (72% increase in travel time)
• Lakeshore Blvd. (30% increase in travel time)
• Cherry St. (27% increase in travel time)
