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 various infrastructure owners throughout Ontario. The Ministry of Transportation (MTO) manages the publishing and electronic distribution of the OPS standards via this website, on behalf of the OPS and they are usually updated twice a year, in April and November.  Further information about the OPS organization can be obtained from their website at and enquiries can be directed via email to

Important Note About the Use of OPS Standards by MTO

It is important for users to note that the use of OPS standards is not mandatory and each Owner determines which standards they will use (if any), which date versions they will use, and when they will implement and/or cancel them.  This means that Owners such as MTO may not be using the most recent version of a particular standard.  In these cases the applicable version will be located under the "Archived" tab.  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 from the Contract Design, Estimating, and Documentation (CDED) Manual, located elsewhere on this website.
