On page 7 of 9 under Section "Construction" it says, "The Contractor shall refer to the work permit application for rates and billing information. MTO will pay the costs of all flagging and other traffic control measures required and provided by the railway company...as per the General Conditions of Contract." Which may implicitly indicate that the MTO's construction contract will have wording in it so that the Contractor essentially sub-contracts the railway flaggers and bills the MTO accordingly.

Is there any guidance for how the MTO (e.g. MTO PM) is supposed to arrange for the railway to be paid when flaggers are needed in the pre-construction stage?

Consider clarifying payment processes. It may be more affective to have a separate section on "Payment Process" for quick/easy referencing.
