Bill 491 amends Quebec’s Public Infrastructure Act to make climate impact a gating criterion for projects placed in the Québec infrastructure plan. It requires the plan to include an assessment of projects’ greenhouse gas (GHG) emissions, creates a new ministerial authorization step before projects are added to the plan, and obliges public bodies to supply information the minister needs to evaluate climate impacts.
The bill gives the Minister of the Environment, the Fight Against Climate Change, Wildlife and Parks explicit authority to refuse projects that would jeopardize Quebec’s GHG reduction targets and to attach, modify or tighten conditions on an authorization to limit emissions. The Government must set assessment procedures and criteria by regulation and retain environmental experts to assist in that work, introducing a regulatory layer that will govern how the climate test is applied in practice.
At a Glance
What It Does
The bill inserts a climate assessment requirement into the Québec infrastructure planning process and creates a ministerial authorization regime: no project can be added to the infrastructure plan without the environment minister’s authorization. Regulations will set the assessment procedures and criteria, and the minister may refuse projects that threaten Quebec’s GHG reduction targets or impose conditions to limit emissions.
Who It Affects
Provincial departments and agencies that propose or manage infrastructure projects, municipalities and Crown corporations that seek inclusion in the infrastructure plan, and project proponents whose projects must now clear a climate test before receiving plan status. Consultants and environmental experts will also be directly engaged under the regulatory design requirement.
Why It Matters
The bill shifts part of project approval upstream into planning by making plan inclusion contingent on climate outcomes rather than leaving climate considerations to later permitting or mitigation. That changes how projects are scoped, funded and prioritized and creates a clear legal lever to align infrastructure investments with Quebec’s climate goals.

What This Bill Actually Does
The bill first amends the Public Infrastructure Act to require the Québec infrastructure plan to include an explicit assessment of the greenhouse gas emissions and climate impacts of the projects it contains, alongside existing budget reporting. That adds a documentation requirement to the plan itself so decision-makers and the public can see how planned investments move the province toward its GHG targets.
Next, the bill inserts a new authorization step: project proponents cannot have a project listed in the infrastructure plan unless the Minister of the Environment, the Fight Against Climate Change, Wildlife and Parks issues an authorization. The authorization is not a ministerial formality.
The minister must refuse authorization if a project would jeopardize Quebec’s GHG reduction targets. To operationalize that standard, the government must make regulations specifying procedures and criteria and must bring in environmental experts to advise or assist in those assessments.When the minister does issue an authorization, the bill gives the minister broad power to attach, alter or add conditions, restrictions or prohibitions aimed at reducing emissions and limiting climate impacts.
The text also lets the minister change conditions for activities already authorized within a project when circumstances or changes in the project warrant further restrictions. Finally, the bill requires government bodies to provide information to the minister in the form and timeline the minister sets so the minister can carry out the assessment and prepare the plan’s required emissions report.
The Five Things You Need to Know
The bill requires the Québec infrastructure plan to be accompanied by an assessment of projects’ greenhouse gas emissions and climate impacts (amendment to section 6).
No project may be added to the Québec infrastructure plan without an authorization from the Minister of the Environment, the Fight Against Climate Change, Wildlife and Parks (new section 6.1).
The minister must refuse authorization if the project jeopardizes Quebec’s greenhouse gas reduction targets; the government will set, by regulation, the assessment procedures and criteria and must retain environmental experts to assist (new section 6.1).
When issuing or reviewing an authorization, the minister may prescribe, modify or add conditions, restrictions or prohibitions to limit greenhouse gas emissions and climate impacts, including modifying conditions for previously authorized activities (new section 6.2).
Government bodies must provide the minister, in the time and form the minister determines, with the information required to assess projects’ greenhouse gas emissions and climate impacts (amendment to section 10).
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Add emissions assessment to the infrastructure plan
This amendment expands the plan’s accompanying documents to include an assessment of infrastructure projects’ greenhouse gas emissions and climate impacts in addition to the usual past- and forward-looking financial reporting. Practically, ministries and agencies that prepare the plan will need to quantify or qualitatively describe emissions for listed projects and explain their expected contribution to provincial targets; that information becomes part of the statutory planning record.
Ministerial authorization required before plan inclusion
This new provision bars adding any project to the infrastructure plan without prior authorization from the environment minister and sets a substantive refusal standard: the minister must refuse authorization where a project would jeopardize Quebec’s GHG reduction targets. The provision delegates to the Government the task of making regulations that establish assessment procedures and criteria and requires the government to retain environmental experts — signalling that the law contemplates technical, standardized climate testing rather than only case-by-case ministerial judgment.
Minister may impose and alter conditions to limit emissions
This clause gives the minister power to impose conditions, restrictions or prohibitions on an authorization aimed specifically at limiting GHG emissions and climate impacts, and to modify or add conditions for activities already authorized within a project. That creates an ongoing regulatory lever: authorization is not fixed once granted and can be tightened if project changes or new information warrant it.
Duty of government bodies to supply information
The amendment requires any government body referenced in section 10 to provide the minister with the information the minister needs to assess projects’ emissions and climate impacts, within the time, manner and form the minister specifies. This allocates the informational burden to provincial actors and enables the minister to demand standardized data, but it also raises administrative coordination needs across ministries and agencies.
Commencement on assent
The act comes into force on the date of assent. There is no staged commencement or transitional grandfathering language in the bill text, so the authorization requirement and reporting obligation would apply as of the act’s entry into force unless future regulations or implementation guidance provide transition rules.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Quebec’s climate governance and target tracking — the statutory requirement creates a planning-level checkpoint to keep infrastructure aligned with GHG targets and makes emissions part of the official plan record, improving transparency and accountability.
- Communities exposed to climate risk — by forcing emissions and climate impact analysis earlier in the planning process, the bill helps surface projects that would increase vulnerability or lock in high-emitting infrastructure, supporting climate-resilient choices.
- Environmental NGOs and experts — the requirement to retain environmental experts and the new ministerial gate provide civil society and technical specialists clearer legal and procedural hooks to contest or influence project selection and mitigation measures.
Who Bears the Cost
- Provincial ministries and Crown corporations that prepare infrastructure proposals — they'll need to produce emissions assessments, respond to ministerial information requests and redesign projects to meet climate criteria, increasing planning and consulting costs.
- Project proponents and contractors — proponents may face delayed inclusion in the plan, added design and mitigation obligations, or refusal; complying with new conditions will add capital or operating costs and possibly change procurement timelines.
- The Ministry of the Environment and its staff — the ministry gains a significant new workload and must manage technical reviews, impose and monitor conditions, and possibly defend contentious refusals; it may require new resources or expert contracts to carry out these duties.
Key Issues
The Core Tension
The central tension is between accelerating a credible, enforceable alignment of provincial infrastructure with Quebec’s climate targets and the legal, administrative and economic friction that creates: making the infrastructure plan a substantive gate protects long-term climate goals but risks procedural uncertainty, delays, and increased costs for projects and for government implementation capacity — a trade-off between climate integrity and project predictability.
The bill sets an outcome-oriented refusal standard — projects that “jeopardize” achievement of GHG reduction targets — but it leaves the operational definition of that phrase to regulation. That gap gives the government flexibility to calibrate the test, but it also creates uncertainty for proponents and for the minister’s office during early implementation.
The requirement to retain environmental experts suggests assessments will be technical, yet the bill does not specify methodology, metrics (e.g., lifecycle vs. operational emissions), baseline year, or the time horizon for evaluating climate impacts; those choices will materially affect which projects pass the test.
The minister’s power to modify conditions for previously authorized activities is a strong tool for adaptive management, but it raises enforcement and legal questions. Retroactive tightening of conditions may be contested by proponents on grounds of regulatory expropriation or contractual interference, and the bill does not set procedural safeguards (notice, timelines, appeal routes) for such modifications.
Finally, the bill’s interplay with federal environmental assessment processes and with existing sectoral approval regimes is not addressed; coordination will be necessary to avoid duplicative or conflicting requirements and to determine whether plan exclusion effectively blocks projects that might otherwise secure permits under other schemes.
