Ivan B. Wallace
Ontario Land Surveyor Ltd.
The History of IBW is a complex one. While the firm was incorporated in 1991 the history actually dates back to 1950 when Graydon T. Horton opened his practice in Ajax, Ontario. The firm that eventually became Horton, Wallace and Davies enjoyed several incarnations such as G.T. Horton and Assoc., Horton, Carr and Haynes, Horton & Haynes, Horton & Wallace before finally becoming Horton, Wallace & Davies in 1980 upon the retirement of Mr. Horton. The firms had offices in Toronto, Ajax, Whitby, Bowmanville, Cobourg, Trenton, Belleville, Stirling, Picton and Haliburton over those 40 years.
The firm’s office all became independent in 1990 as the Quinte and Cobourg offices were sold to their managers and finally the Bowmanville Office became Ivan B. Wallace OLS Ltd. IBW spent the next few decades rebuilding as we reacquired the Northumberland Office and Re-entered Quinte and Prince Edward County with the purchases of Kerry Boehme OLS, Wayne Wollerman and Roger Pickard OLS. Other notable practices purchased were Coutts and Flim, Bill Brick OLS, 43 Degrees North, Keith Lashley OLS, Gary Parker OLS, Charles Riley OLS and Brown and Coggan OLS. Once again our focus is providing quality surveys from Toronto right through to Kingston.
Upon Ivan’s semi-retirement in 2001 the IBW direction was then steered by Crystal Cranch and Gord Wallace until Dave Comery arrived back in 2007 which was the start of our tremendous growth. The timely arrivals of Dwayne Cummings shortly after and Robert Wannack in 2012 rounded out the current IBW directors.
We are now working hard in helping reshape the urban infrastructure with our well guided staff and always the best equipment operated by our dedicated staff.
