The Canadian Interoperability Technology Interest Group (CITIG) was created in 2007 to improve Canadian public safety communications interoperability. It is a responder-driven, federally-funded activity, led by the Canadian Police Research Centre that brings together responders, academia, industry and government stakeholders who share a common interest in enhancing Canada's communications interoperability and are dedicated to improving the safety and security of first responders, and the people and critical infrastructure of Canada. CITIG was formalized when the Canadian Police Research Centre (CPRC) and the Canadian Association of Chiefs of Police (CACP) joined forces with the Canadian Association of Fire Chiefs (CAFC) and Emergency Medical Services Chiefs of Canada (EMSCC) to work together to improve public safety interoperability in Canada.

Today, CITIG is made up of more than 500 volunteer members from the responder community, all orders of government, non-governmental organizations, associations, academia and industry.
