Ontario Provincial Standards (OPSS and OPSD)

The Ontario Provincial Standards for Roads and Public Works (OPS) organization produces a comprehensive set of standards for use by road and public works owners, contractors, and consultants in Ontario. Further information about the OPS organization can be obtained from their website at www.ops.on.ca and enquiries can be directed to Ontario.Prov.Standards@ontario.ca

Ontario Provincial Standard Specifications (OPSSs) and Drawings (OPSDs) are updated twice a year, in April and November. The Ministry of Transportation (MTO) manages the publishing and electronic distribution of the OPS standards via this website, on behalf of the OPS.

Important Note About the Use of OPS Standards by MTO

It is important for users to note that the use of OPS standards by MTO and other infrastructure owners is not mandatory. Each Owner determines which standards they will use, which date versions they will use, and when they will implement and/or cancel them.

The specific standards that have been implemented for use for the design of MTO highway facilities are listed as "Active" in the ministry's Contract Preparation System (CPS). Users without access to CPS can obtain lists of the standards that have been implemented in CPS, from the Contract Design, Estimating, and Documentation (CDED) Manual.
