The journey to becoming RE/MAX Hallmark Realty Group began in 2001, when Jeff and Margie Hooper opened KW Ottawa Realty which was the first KW office to open in Ontario. It then grew to be the largest KW office in Canada with nearly 300 agents. In 2016, RE/MAX Hallmark Realty Ltd. officially "partnered" with Keller Williams Ottawa Realty. With this partnership KW Ottawa Realty became RE/MAX Hallmark Realty Group and has since grown to over 400 agents and staff with 4 locations across Ottawa.
