NOTE: The target implementation dates below have been revised.

The TTC supports and encourages contractors  to engage the community via various available youth apprenticeship and training programs including, but not limited to Hammer Heads, LIUNA BOLT, Carpenter Council of Ontario ‘CHOICE’, Helmets to Hardhats, etc. which provide participants with leadership and mentoring opportunities that will lead to development of valuable skill sets, self-confidence and promote positive self-awareness. 


NOTE: The below target implementation dates have been revised as of May 9, 2016.
This will serve to notify that the TTC is implementing the Certificate of Recognition (COR™) safety program for its construction projects. The COR™, issued by the Infrastructure Health and Safety Association (IHSA), will supplement TTC’s current safety requirements, such as WSIB clearance certification and corporate and site specific safety plans, prior to commencement of any construction work.  Construction contractors’ bidding on future TTC projects will be required to have COR™ in order to be considered for any award and further, must maintain certification in good standing for the duration of any awarded contract.

TTC has implemented the COR™ requirement for contracts estimated at greater than $25M as of July 1, 2014.

TTC will continue implementing the COR™ requirement in a phased approach to ensure that the number of certified contractors is sufficient to allow for competitive bidding.  Consequently, contractors interested in bidding TTC construction work are encouraged to familiarize themselves with COR™ and the respective requirements for the program. 

The revised target implementation dates for mandatory COR™ for TTC construction contracts are as follows:

  • July 1, 2016 for contracts estimated at greater than $5M - Contractors must be COR™ registered.
  • January 1, 2017 for contracts estimated at greater than $5M - Contractors must be COR™ certified.
  • January 1, 2018 for all contracts, irrespective of value - Contractors must be COR™ certified.

Contractors who do not yet possess COR™ and wish to obtain information about the certification, are advised to contact:
