Bill C-205 amends the Impact Assessment Act to prohibit any regulation made under the Act from prescribing a minimum coal production capacity for a "new coal mine" whose construction, operation, decommissioning and abandonment could be designated as a physical activity. The change is implemented by renumbering section 109 as subsection 109(1) and adding a new subsection 109(2) that contains the prohibition.
The practical effect is to prevent the government from using production-volume thresholds in regulation to exclude smaller coal mines from the federal designation process. That narrows a straightforward regulatory route for drawing a size-based exemption, which may increase the universe of projects that can be designated for federal impact assessment while leaving open other, non-production-based criteria for designation.
At a Glance
What It Does
The bill adds subsection 109(2) to the Impact Assessment Act prohibiting regulations under section 109 from specifying a minimum coal production capacity for a "new coal mine" that is or could be designated as a physical activity. It does not itself designate projects or create new assessment triggers.
Who It Affects
Provincial and federal regulators who draft designation regulations, coal mine proponents (including junior and small-scale operators), Indigenous groups and communities near proposed mine sites, and the Impact Assessment Agency tasked with processing potential designations.
Why It Matters
By removing production-volume as a permissible regulatory cutoff, the bill makes size-based regulatory carve-outs for coal mines harder to deploy, potentially widening the set of projects subject to federal scrutiny and increasing uncertainty and workload for industry and the Agency.

What This Bill Actually Does
Section 109 of the Impact Assessment Act governs the government's power to make regulations that designate physical activities subject to federal impact assessment. Bill C-205 changes that section by adding a targeted limitation: regulations cannot establish a minimum coal production capacity to define a "new coal mine" for designation purposes.
Practically speaking, regulators can no longer say "only mines producing X tonnes per year or more may be designated" in the text of a regulation.
The amendment is narrowly framed. It addresses only one type of regulatory criterion — a minimum production-capacity threshold for coal — and does not itself change which activities are designated, does not create an automatic trigger based on production, and does not require the Minister or Agency to designate any particular project.
The government retains other tools to define or limit designations, such as geographic criteria, disturbance-area thresholds, proximity to sensitive sites, or activity descriptions that do not refer to production capacity.Because the bill forbids one regulatory shortcut for excluding small projects, its intended effect is to ensure that even lower-capacity coal mines can be captured by the federal designation process if the government chooses. That can expand opportunities for federal review and oversight of environmental and socio-economic effects for smaller or incremental coal developments.
At the same time, the ban leaves open regulatory workarounds and creates new implementation questions for the Impact Assessment Agency and drafters of regulations about how to set clear, legally defensible criteria that achieve policy objectives without relying on production-volume cutoffs.
The Five Things You Need to Know
The bill renumbers existing section 109 as subsection 109(1) and inserts a new subsection 109(2) into the Impact Assessment Act.
Subsection 109(2) expressly prohibits a regulation made under subsection (1) from setting a minimum coal production capacity for a "new coal mine" that is a designated physical activity under paragraph (1)(b).
The prohibition applies to regulations that would use production-volume thresholds to define the scope of projects eligible for federal designation, but it does not itself designate any activity or impose an assessment requirement.
The bill is limited to "minimum coal production capacity" — it does not prohibit regulations from using other metrics (for example, land disturbance, greenhouse gas emissions, or proximity to protected areas) to define or exclude projects.
Because the bill removes a straightforward size-based exclusion, it could increase the number of coal projects that the federal government can choose to designate for impact assessment, raising potential workload and legal questions for regulators and proponents.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Technical renumbering to prepare for the new provision
The bill begins by renumbering the existing section 109 as subsection 109(1). This is a drafting step that preserves the current authority to make designation regulations while creating space in the statute for the new limiting subsection. Draftingwise, it keeps the Act's structure tidy and signals that the change is an amendment to the existing regulatory power rather than a wholly new power.
Ban on minimum coal production capacity in regulations
The inserted subsection states that a regulation made under subsection (1) must not set out a minimum coal production capacity in respect of a "new coal mine" whose construction, operation, decommissioning and abandonment is a designated physical activity under paragraph (1)(b). In practice, this stops regulators from using a single, quantitative production threshold to exclude smaller coal mines from being designated for federal assessment. The provision is narrowly worded: it targets only "minimum coal production capacity" as a permissible regulatory criterion.
What the prohibition does — and does not — prevent
The statutory ban addresses only one category of regulatory criterion and leaves the broader designation authority intact. Regulators may still craft definitions and exclusions based on non-production characteristics (for example, area disturbed, depth, method, or environmental sensitivity). The provision therefore redirects regulatory drafting away from tonnage cutoffs and toward other qualifying or limiting factors, which could be legally contested if they replicate the effect of a production threshold in substance rather than form.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Nearby communities and Indigenous groups — The prohibition makes it easier for regulators to designate smaller coal projects, increasing opportunities for federal review of environmental, cultural and socio-economic impacts that local communities are concerned about.
- Environmental organizations and advocates — Groups pushing for broader federal oversight of coal development gain a statutory tool that limits the government's ability to create size-based exclusions.
- Federal oversight bodies (on a policy basis) — If the government chooses to designate smaller projects, the Agency and Minister gain discretionary reach to assess cumulative effects from multiple smaller mines that collectively have significant impacts.
Who Bears the Cost
- Mining companies, especially junior and small-scale operators — Without a production-based regulatory floor, smaller projects face a greater prospect of federal designation, adding time and expense to project development and permitting.
- Impact Assessment Agency of Canada and federal departments — Potentially increased volume of designation referrals and assessments would raise administrative workload and resource needs for federal officials.
- Provincial regulators and proponents — The change can increase federal-provincial overlap and coordination needs, complicating approval pathways and potentially leading to duplication or disputes over jurisdiction.
Key Issues
The Core Tension
The central dilemma is between strengthening federal oversight to capture smaller coal projects that may have cumulative environmental and community impacts, and maintaining predictable, administrable rules that give industry and regulators certainty; the bill removes a simple size-based exemption but does not resolve how to draw legally durable boundaries that balance oversight, efficiency and investment certainty.
The bill's narrow technical change creates broader practical questions. It removes a clear, easily administrable metric (production volume) from the toolbox regulators can use to calibrate scope; that increases discretion but also increases uncertainty.
Drafters can still achieve similar ends by using other measurable criteria (area disturbed, annual throughput measured differently, method of extraction, or GHG-emission thresholds). Those alternatives may be functionally equivalent to a production cutoff and could invite legal challenges alleging that regulators are circumventing the statutory ban by repackaging size-based exclusions.
Another implementation challenge is capacity and timing. If regulators and the Minister respond by designating more smaller mines, the Impact Assessment Agency may need additional resources, and proponents will face longer timelines and higher costs.
That raises trade-offs between environmental oversight and predictability for investment. The bill also touches federal-provincial relations: provinces that approve smaller projects under their own regimes may see more federal engagement, requiring clearer coordination protocols to avoid duplicative reviews or jurisdictional conflict.
