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.
