Welcome to the City of Toronto website

With the recent introduction of Ontario Regulation 216/10 under the Surveyors Act on June 7, 2010, plans registered or deposited with the Registry Office must be integrated in the North American Datum 1983 (NAD’83) in either the NAD’83 Adopted or the NAD’83 CSRS datum definition with the coordinates expressed in either the 3 Degree Modified Transverse Mercator or 6 Degree Universal Transverse Mercator Projections.

To support integration under the Regulation, the City of Toronto has prepared this guide to facilitate surveyors and other groups using the City’s horizontal control network to integrate their projects in NAD’83 CSRS.
