The Delay Ledger: Analyzing the TTC's Shift From Weather to 'Disorderly Patrons'

### The Data Breakdown

An analysis of Toronto Transit Commission (TTC) subway delay logs spanning 2018 to 2025 reveals a system struggling with a significant increase in both the frequency and duration of service interruptions. As CBC Toronto first reported, cumulative delay time has risen by 53% since 2019.

In 2019, total delays amounted to 770 hours and 41 minutes. By 2025, that figure climbed to 1,179 hours and 28 minutes. The 2025 logs recorded 25,737 individual delay incidents; while more than half of these resulted in no actual service delay, those that did impact riders ranged from brief two-minute interruptions to a single event lasting 15 hours.

### A Shift in Failure Points

While the volume of delays has increased, the nature of the disruptions has undergone a fundamental shift. CBC Toronto reports that prior to the pandemic, specifically in 2018 and 2019, weather-related issues were the most common cause of delays. During those years, "disorderly patron" incidents ranked only sixth in terms of frequency.

In the current landscape, the trend has reversed. For the last three years, "disorderly patron" has become the leading cause of delays. In 2025, these incidents accounted for more than 127 hours of cumulative delay time. TTC spokesperson Stuart Green clarified that these incidents include non-criminal matters, such as loud or unruly passengers, and are distinct from assaults, which the data shows are much less frequent.

Other frequent causes of disruption identified in the logs include passenger alarm activations and passengers who are ill or injured.

### The Human Element

Transit experts and advocates suggest the data reflects broader societal pressures. Andrew Pulsifer, the executive director of the advocacy group TTCRiders, told CBC Toronto that the increase in mental health incidents, drug use, and homelessness in society is reflected on public transit. Pulsifer noted that while the introduction of crisis workers has been a positive step, increased staffing could further reduce the length of delays by improving response times.

Jonathan English, a transit researcher and consultant, noted that this trend is not unique to transit, stating it is something seen in many other areas following the pandemic.

For his part, Stuart Green stated that the TTC is using this data to drive operational improvements, increase support visibility, and deploy staff to high-need areas. Green also noted that the TTC has encouraged the use of the SafeTTC app for reporting concerns, which may be contributing to the higher number of logged incidents.

### The Invisible Decay: Slow Zones

Despite the granularity of the delay logs, a significant point of infrastructure failure remains absent from the raw incident data: slow zones. These are sections of track—primarily on Line 1—where trains must operate at reduced speeds, sometimes as low as 15 km/hr, to ensure safety in areas requiring maintenance.

Because slow zones are persistent conditions rather than isolated "incidents," they are not recorded in the same logs as disorderly patrons or weather events. However, as of last week, 17 such slow zones were active.

Andrew Pulsifer told CBC Toronto that these slow zones are "probably one of the biggest barriers" for riders and represent a persistent reliability issue that the standard delay logs fail to capture.
