The OCEHT began as a sub-committee of PACT- Ottawa (Persons Against the Crime of Trafficking in Humans). The committee brought together agencies in the National Capital Region that were ready, willing and able to assist a trafficked person. In 2013, the OCEHT became a distinct and separate organization from PACT-Ottawa, but continued with its established mandate. A mandate that focuses on meeting the resource and support needs of trafficked persons, and to provide training on human trafficking to service providers. A new chapter of the OCEHT had begun.

Currently, the Coalition boasts representation from over 65 organizations. Within this collaborative environment, members can cultivate innovative approaches, share knowledge and expertise, discuss effective strategies, engage in collective problem-solving, and pool their resources and expertise to combat human trafficking. This collective effort is instrumental in advancing the fight against human trafficking, fostering a safer community for all and, more importantly, being a voice for survivors of human trafficking. Its mandate is supported by the work of 10 committees along with a group of Observing Members and Network Members, as well as volunteers that coordinate training, Member / volunteer recruitment, events and communications.
