The various office's of Horton, Wallace & Davies each became independent in 1990 as the Cobourg and Quinte offices were sold to their managers and finally, the Bowmanville office became Ivan B. Wallace O.L.S. Ltd. in 1991. Ivan B. Wallace O.L.S. Ltd. spent the next few decades rebuilding and acquiring firms along the Highway 401 corridor, once again entering into the Cobourg an Quinte offices with an additional focus on providing quality surveys from Toronto right through to the Quebec border. In 2022, Ertl Surveyors of Richmond Hill strategically merged their operations with Ivan B. Wallace OLS Ltd, prompting a name change to what is now known as IBW Surveyors Ltd.
