The STM does not keep separate accounts for Metro and buses services, therefore the following figures include both activities. In 2016, direct operating revenue planned by the STM totalled $667 million. To compensate for the reduced rates, the city will pay $513 million plus $351 million from Quebec. For a budget of $1.53 billion, salaries account for 57% of expenditures, followed in importance by financial expenses (22%) resulting from a 2.85 billion debt. For the Metro only, wages represented 75% of the $292 million operating costs, before electricity costs (9%).
