Metrolinx Technical Standards

There are three ways to search for a standard document:

1. Download the Master List of Standard Documents to access a comprehensive record of all published standard documents. This list includes key information such as: the location of the document, amendment record information and document description.
2. Visit the Document Centre to search for specific standard documents, keywords or relevant topics.
3. Browse the website by navigating between Engineering & Architectural Standards and Other Technical Standards sections. For additional guidance on locating standard documents, download the How-to Guide.

Click on “Filter Documents” next to the search bar. Select “GO Engineering” by checking the box, then close the filter menu. In the search bar, type the document name, document number, or keywords, and press Enter.

Once you locate the standard document in the Document Centre, click on the Export icon.

• If the document is in PDF format, you will need to manually save it to your desktop.
• If the document is in DOCX, XLSX, or ZIP format, it will be automatically downloaded to your desktop.

Archived standard documents are available on the Archived Standards page. They are sorted alphabetically by document name, and each document is watermarked based on its status as either superseded or obsolete.

You can check for document revisions and their reasons through the following:

1. Publication News - Provides announcements and updates on newly released or revised standard documents, organized by month.
2. Amendment Records - Document the history of changes made to standard documents. These records can be found within the respective asset class pages.

Archived standard documents are available from January 2024 onward. If the document was archived before this date, please contact the SME team for a copy.

Standard documents are categorized into two main sections:

1. Engineering & Architectural Standards - Further divided into:
• Asset-Specific Standards - Includes standards related to specific engineering asset classes.
• Non-Asset Specific Standards - Covers general engineering standards that are not tied to a specific asset class.
2. Other Technical Standards - Contains all technical standards that do not fall under Engineering & Architectural Standards such as:
• Payments (PRESTO)
• I&IT
• Universal Design & Wayfinding
• Rail Corridor Access & Control
• Station Services

Reference documents within the Standards are managed by the Capital Project Group and are the responsibility of the PDT to provide them. Contact your Mx project contact and they will be able to provide you with a copy of all reference documents applicable to your project.
