Welcome to the MTO Technical Publications website! This site houses documents that are used for the design, construction, and maintenance of the ministry’s transportation facilities in Ontario.  Before proceeding, please consider taking a few moments to view our How to Guide for some quick tips on how to easily find what you need.

A broader collection of documents and other materials is available from the MTO Online Library, and future documents that are currently under development are available from the MTO Technical Consultation Portal.

As outlined in the OPS Accessible Customer Service Policy, we are committed to providing accessible customer service, therefore upon request, we can arrange for accessible formats and communication supports.
