Public transit reference guides 

Guide des principes d'aménagement et d'accessibilité universelle

This document underscores the importance of taking public transit into consideration in:

  • planning;
  • land use planning; 
  • neighbourhood development; and
  • new construction projects. 

It aligns with one of the goals in the STO’s 2017-2026 strategic plan, which is to play an active role in land use planning and development to promote an efficient and accessible public transit system.

Guide de conception et de normes de services

This document defines and standardizes the review process for the services offered. It covers the fundamental aspects of planning the public transit service, including:

  • minimum service levels; 
  • supply management; and 
  • information for customers. 

It serves to guide us in the planning, review and adjustment of our services.
