Callon Dietz has a rich history of surveying throughout Ontario. We begin a typical project by researching available records from many sources to ensure we have first-rate information and evidence to complete the project. We then choose only the best combination of equipment to finish the project safely, accurately and efficiently so that we deliver the best product to our clients.
Callon Dietz started in 1967 as T.O Callon Limited and changed its name when Terry Dietz became a partner.
Expanding throughout the province to better service and reach our customers, Callon Dietz has offices in London, North Bay, Oshawa and Ottawa.
