The network operations funding (maintenance, equipment purchase and salaries) is provided by the STM.
However, tickets and subscriptions cover only 40% of the actual operational costs, with the shortfall offset by the urban agglomeration of Montreal (28%), the Montreal Metropolitan Community (5%) and the Government of Quebec (23%).

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%).

Heavy investment (network extensions) is entirely funded by the provincial government.
Renovations and service improvements are subsidized up to 100% by the Government of Canada, the province and the urban agglomeration.
For example, 74% of the rolling stock replacement cost is paid for by Quebec while 33% of the bill for upgrades to ventilation structures is covered by the federal government.
Small investments to maintain the network in working order remain entirely the responsibility of the STM.
