Energy Data and Utility Bill Audit in Montreal
MartinAI turns the utility bills behind every building in Montreal, Quebec into clean, audited, report-ready data, across electricity, gas, water, steam, and more.
For owners, operators, and energy teams in Montreal, the utility bill is the single most complete source of truth about a building, and the hardest to use. Quebec's inexpensive, low-carbon hydroelectricity supports energy-intensive industry such as aluminum smelting and has attracted data centre investment, alongside a large public and commercial building sector in Montreal and Quebec City. MartinAI exists to turn that source into structured, trustworthy data. As a city in Canada, Montreal has its own utilities, regulator, and reporting rules, and this page covers what that means for your data.
The energy picture in Montreal
| Grid carbon intensity | about 1.2 g CO2e/kWh (2022) |
|---|---|
| Grid mix | About 94 percent hydro, with roughly 5 percent wind and the small remainder from bioenergy, natural gas, and other sources |
| Main electricity utilities | Hydro-Quebec and Hydro-Sherbrooke |
| Main gas utilities | Energir and Gazifere |
| Energy regulator | Regie de l'energie du Quebec |
Montreal draws from the Quebec grid, so its electricity carbon intensity reflects that grid. At about 1.2 grams of CO2e per kilowatt-hour (2022), electricity here is among the cleanest in Canada. That changes where the biggest carbon savings sit: with such clean power, the largest reductions usually come from cutting natural gas and heating fuel, and from trimming peak electricity demand rather than total kilowatt-hours.
On the ground in Montreal
- Electricity is delivered locally by Hydro-Quebec, within the Regie de l'energie du Quebec framework.
- Local reporting rule: By-law 21-042, GHG emission disclosure and rating of large buildings.
- Largest city in Quebec.
Getting your utility data in Montreal
Hydro-Quebec's online Customer Space lets customers view and download hourly and daily consumption data from installed smart meters. Quebec has no Green Button mandate comparable to Ontario's.
What MartinAI delivers in Montreal
Whether a building is served by Hydro-Quebec and Hydro-Sherbrooke, or any other provider, MartinAI reads its utility bills across every commodity and layout, separates true consumption from delivery, demand, and tax lines, and validates each figure before it reaches a report. The result is one clean record per building that you can analyze, benchmark, and hand to an auditor.
Data delivery
Every utility bill read across electricity, gas, water, steam, and fuels, normalized to consistent units and periods.
Bill audit
Rate class, demand, tax, and meter mapping checked against the tariff and the meter to recover overcharges.
Benchmarking
Clean records that feed ENERGY STAR Portfolio Manager and internal intensity comparisons across sites.
Emissions reporting
Consumption paired with the right local emission factor for defensible Scope 1 and Scope 2 numbers.
Utility bill audit in Montreal
An audit is where clean data pays for itself. With every bill in Montreal read and validated, the anomalies surface: a wrong rate class, a demand charge inflated by one bad interval, tax applied where it should not be, consumption billed to the wrong meter. Industry figures put utility billing errors at 2.5 to 10 percent of spend, so the recovery is often material.
Reporting and compliance in Quebec
There is no province-wide benchmarking mandate, but the City of Montreal's By-law 21-042 requires owners of large buildings (2,000 square metres or more, or 25 or more dwellings) to disclose annual energy and GHG data via ENERGY STAR Portfolio Manager and receive a GHG performance rating. Federal direction is moving toward CSDS and OSFI climate disclosure standards.

Frequently asked questions
Can MartinAI handle utility bills from Montreal and Quebec?
Yes. MartinAI reads utility bills across every commodity (electricity, natural gas, water, steam, and fuels) and every layout used by utilities in Quebec, then validates each figure. Local formats and multi-meter accounts are exactly what it is built for.
What is the grid carbon intensity in Montreal?
Grid electricity in Montreal, which sits on the Quebec grid, is about 1.2 grams of CO2e per kilowatt-hour (2022). MartinAI pairs your validated consumption with the right local emission factor so your Scope 2 numbers are accurate.
Do you help with energy reporting rules in Quebec?
There is no province-wide benchmarking mandate, but the City of Montreal's By-law 21-042 requires owners of large buildings (2,000 square metres or more, or 25 or more dwellings) to disclose annual energy and GHG data via ENERGY STAR Portfolio Manager and receive a GHG performance rating. Federal direction is moving toward CSDS and OSFI climate disclosure standards. MartinAI produces the clean, traceable data those reports depend on.
How is this different from reading bills by hand?
Manual entry is slow and error prone, and the errors flow straight into your cost and emissions numbers. MartinAI reads and validates automatically, flags anomalies, and keeps every figure traceable back to the source bill, so the data holds up under an audit.
