STM funding delays cost Montreal transit millions and stall major projects
Quebec study finds STM funding delays lead to $159 million in bank fees and years of waiting for authorizations
Quebec’s approval process is forcing the Société de transport de Montréal to shoulder significant short term borrowing costs and delaying major infrastructure projects. The issue of STM funding delays was highlighted in a recent budgetary study that says the agency waits on average about three years for financing authorizations from the provincial ministry. Documents reviewed by media show $159 million in bank fees tied to 18 active projects and growing interest charges that shrink project scopes.
Average wait for ministerial authorization
The study of the ministry of Transport and Sustainable Mobility budget shows a consistent lag between projects being listed in the Plan québécois des infrastructures and receiving funding authorization.
STM materials and the study indicate that once a project is included in the provincial infrastructure plan, it nonetheless faces additional steps before the ministry signs off on subsidy requests.
The transit agency notes typical authorization timelines range from two to five years, and the study data suggest the average delay is nearer three years. These prolonged waits create uncertainty for project scheduling and financing.
Bank fees and lost capital for transit projects
Documents consulted for the study confirm the STM has paid $159 million in banking and financing fees across 18 ongoing works.
Officials describe those costs as the equivalent of losing the purchasing power of more than 80 buses, a comparison that underscores the operational impact of financing charges. The fees also reduce the funds available for construction and can force the agency to trim project features.
These charges include interest on short term loans taken to keep construction on schedule while grant authorizations remain pending. Some of the fees are eligible for provincial reimbursement but others are not, which erodes STM reserves.
Blue Line extension advanced hundreds of millions
The STM advanced $910 million of its own funds to begin work on the Blue Line extension while waiting for approval of roughly $5 billion in financing requests.
As of April 30, 2026 the agency reported the wait for letters of authorization for the project had reached 1,164 days and the timetable remained unresolved. The prolonged delay has generated $66 million in financing costs for the extension to date.
Federal contributions further complicate the picture. Ottawa approved $1.9 billion in federal support for the Blue Line in July 2024 but the STM cannot bill those federal programs without initial provincial authorization from the ministry. That restriction has forced the agency to remove $23 million from operating budgets to cover ineligible charges and to protect project continuity.
Longstanding projects still waiting answers
Several projects have been stalled for years after entering the provincial infrastructure plan. The planned expansion of the Viau attachment centre, for example, has been waiting for responses for 1,628 days since it was first proposed.
In the absence of ministerial authorizations, the STM resorts to short term borrowing and cash reallocation to avoid halting construction timelines. That strategy preserves project momentum but increases borrowing costs and strains liquidity across the agency.
Project managers warn that continued delays threaten to reduce the scale of works, delay delivery dates and increase overall lifecycle costs for transit infrastructure.
Accounting rule changes and ministry explanation
Provincial officials acknowledged that changes in public sector accounting practices have altered how projects are launched and funded. The ministry’s senior management told committee members that under previous accounting rules transport agencies could sometimes begin work after being listed in the provincial infrastructure plan without the ministry’s formal approval of funding.
The ministry’s representative suggested that in some cases applicants did not file subsidy requests promptly under the old regime, which may have contributed to administrative delays. New accounting standards applied since April 2024 restrict starting work before approvals are in place, aligning provincial practice with federal requirements.
Despite recognition of the issue, ministry officials had not provided detailed responses to questions about current authorization timelines at the time the study was released. Requests for clarification were reported to remain unanswered.
Operational and financial consequences for STM
The interplay of slower authorization, short term borrowing, and eligibility limits for federal programs has immediate fiscal consequences for Montreal’s transit agency.
Financing costs that could be reimbursed reduce the net impact, but ineligible charges and the need to advance work from internal funds directly cut into operating budgets and capital envelopes. That narrowing of available capital increases pressure on service budgets and could delay future upgrades.
The STM warns that scaled back projects or deferred investments are likely if authorization delays persist, a prospect that would affect ridership capacity and long term network resilience.
Quebec’s budgetary study has brought renewed attention to the mechanics of project approval and the downstream costs of prolonged waiting periods. Faster, more predictable authorization timelines would reduce reliance on costly short term borrowing and protect the purchasing power assigned to transit expansions and maintenance.
