overdoses have continued to trend downward trend in ottawa since peaking in 2023, but there are deadly fluctuations in the trend, according to data from ottawa public health and the ottawa police service.
police responded to 45 per cent fewer
overdose calls in 2025 than a year earlier: 810 calls compared with 1,480 in 2024. that continued a downward year-over-year trend that began in 2023.
but that trend has turned around for the first few months of 2026.
in february, police responded to 51 overdose calls — a jump of 82 per cent compared to the same month a year earlier. there had been a similar year-to-year jump in january. as of the end of february, ottawa police had responded to 93 calls involving overdoses in 2026.
ottawa police service spokesperson julie kavanagh said police calls did not represent a complete picture of overdoses in the city. ottawa fire services and the ottawa paramedic service are also dispatched to medical calls and often take the lead in medical care.
“as a result, fluctuations in police call volumes do not necessarily reflect the total number of overdoses occurring in the community,” kavanagh said.
“both the availability and the
toxicity of the illicit drug supply play key roles in overdose trends. increased availability or a more toxic supply can usually lead to more emergency calls, while reduced availability or lower toxicity can result in fewer calls. these shifts can happen quickly and may contribute as to why 2025 saw lower call volumes overall while early 2026 appears to show an increase.”
overdose-related emergency department visits in ottawa also decreased in 2025, although significant fluctuations were related to the drug supply and other factors, according to ottawa public health data.
in 2025, 607 people visited ottawa emergency departments for overdose-related care compared to 941 people in 2024, the oph data showed, but there was a dramatic increase in emergency room visits between may and september 2025.
