This article examines 9-1-1 call data of the City of Lethbridge in Alberta, Canada over a year to find discernible spatial and temporal trends that may be useful to emergency response or better delivery of emergency management services. The spatial analysis includes Geographic Information Systems hotspot analysis of cellular and landline emergency calls with respect to critical (emergency and healthcare) facilities as well as emergency calls from residential landlines. The temporal analysis looks at hourly, daily, and monthly patterns of emergency calls and the factors driving up the call volumes in certain periods.
