The percentages can differ, and obviously in a case such as Barrie, which has expanded into a bedroom community of Toronto, and there are still some rural areas serviced, it's probably a little bit higher.
In the city of Toronto, where I was a firefighter for 28 years, on average Toronto firefighters are on scene first or simultaneously with EMS 50% of the time. So I would say 50% would be the low end; it's anywhere between 50% to 100% of the time. For the vast majority, over 95% of the professional fire services in Canada provide emergency medical response as part of a tiered response system.
