What Ontario’s 1P1P Permitting Reform Means for Mine Timelines

A previous Ontario environmental assessment took 1,349 days to complete. Of that stretch, 63% was consumed not by scientific study, not by public hearings, but by internal government processing. The bottleneck was not the science. It was the paperwork moving between ministries.

That single figure explains why Ontario built the One Project, One Process framework, launched in October 2025 as a legislative answer to exactly this kind of timeline failure.

To understand whether the framework is a genuine compression mechanism or a rebranded version of the same slow machine, it helps to watch a real project try to use it. Mayfair Gold and its Fenn-Gib project, a 4.3-million-ounce indicated gold resource in Ontario, is one of the clearest current tests.

This is not a news announcement. It is a strategic blueprint worth understanding. Here is what the data tells you about the practical conditions under which the framework can produce an 18-month permitting path rather than a 36-month one, and what Mayfair did for years before submitting its application that most projects cannot replicate on short notice.

What Ontario’s 1P1P permitting framework actually does (and what the old system failed at)

If your instinct is that “streamlined permitting” means a rubber stamp, that instinct is wrong here, and the reason matters. The framework does not reduce the scrutiny applied to any individual assessment. It changes how those assessments move through government.

Under the prior system, standard Ontario permitting historically took roughly three to four years. The delay was structural, and it broke down into a few specific failures.

The broader context for this framework sits in Ontario’s legislative overhaul of 2025 and 2026, where Ontario permitting reform reshaped not only the 1P1P mechanism but also the underlying statutes governing critical minerals development across the province.

• Fragmented ministry interactions, with proponents managing separate relationships across multiple provincial bodies.
• Sequential reviews, where one assessment had to finish before the next could begin.
• Internal government processing that consumed the majority of elapsed time, as the 1,349-day case demonstrates.

The delay was a coordination problem, not a complexity problem A previous environmental assessment took 1,349 days. Internal government processing accounted for 63% of that. The science was not the bottleneck. The hand-offs between ministries were.

That distinction is the key insight. When most of the delay comes from government coordination rather than the difficulty of the assessments themselves, a reform that runs those assessments in parallel can plausibly cut the timeline in half without weakening any single review.

How the Mine Authorization and Permitting Delivery Team works in practice

The mechanism at the centre of the framework is the Mine Authorization and Permitting Delivery Team (MAPDT). It acts as a single point of contact for a designated project, replacing the fragmented ministry-by-ministry approach.

The team coordinates an integrated authorization and consultation plan, then aligns the permitting steps across ministries so they can be reviewed in parallel rather than one after another.

It also oversees Indigenous consultation as a whole-of-project process rather than a separate track running off to the side. That structural choice matters later, and it is why the framework treats consultation as central rather than peripheral.

The official target is at least a 50% reduction in government review timelines, compressing the historical three-to-four-year cycle down to roughly 18 to 24 months. Since the framework launched, 12 potential projects have been identified, and three have been formally designated as of this article.

Ontario’s 1P1P framework is established under section 153.0.1 of the Mining Act, giving the MAPDT its statutory authority to coordinate integrated authorization plans across ministries and set the official 50% timeline reduction target.

For investors tracking development-stage projects in Ontario, this is the analytical filter you need for everything that follows. The compression only benefits projects whose delay would genuinely have come from coordination. A genuinely complex project with unresolved design questions will not be rescued by parallel processing, because parallel processing is not what its problem was.

Why most projects cannot simply apply for 1P1P designation

The speed is real. The entry bar is high enough that most projects will not qualify without years of prior preparation. That tension is the point: designation is a signal of project maturity, not a shortcut available to any applicant who asks.

The critical entry requirement is that a project’s design must be substantially finalised before designation is granted. A fast-tracked parallel process cannot absorb significant mid-review design changes without collapsing the very efficiency gains it was built to deliver.

“Substantially finalised” is abstract until you see what it requires in practice. Mayfair’s preparation is the concrete illustration, and the sequencing tells the story.

1. November 2025: Mayfair began initial engagement with Ontario officials on the 1P1P framework, well before any application.
2. January 2026: Release of a Pre-Feasibility Study (PFS) confirming the project would proceed under Ontario’s Provincial Class Environmental Assessment (EA) pathway, with no Individual EA expected.
3. February 2026: Submission of a Notice of Project Status, formally registering intent to develop Fenn-Gib into a producing mine.
4. April 2026: Appointment of Egis Canada (Ecometrix) as the lead for environmental assessment and permitting.
5. September 2026: Completion of a 23-hole, 6,184-metre condemnation drilling programme confirming no changes to the site layout are required.

Behind those milestones sits more than three years of environmental baseline data, intensified since 2021 across terrestrial and aquatic ecosystems, groundwater, noise, and geochemistry. That data cannot be manufactured at application time. It has to already exist.

The condemnation drilling result is the most underappreciated piece of this strategy. Confirming that proposed infrastructure locations remain suitable means the project enters the process with no redesign risk, precisely the type of uncertainty that causes mid-review delays even inside streamlined frameworks.

For you as an investor, this section rewrites how you should read any future 1P1P application announcement. The question is not whether a company applied. It is whether the preparatory work that makes the framework’s speed achievable was already done before the application landed. Mayfair’s sequencing gives you the benchmark.

The federal threshold decision that changed Fenn-Gib’s regulatory path

The regulatory regime a mine falls under is not always handed to it from outside. Sometimes it is chosen, through a design decision made early enough to shape everything downstream. Fenn-Gib is a case of exactly that.

Under Canada’s Impact Assessment Act (IAA) and its Physical Activities Regulations (SOR/2019-285), a new metal mine with ore production capacity of 5,000 tonnes per day or more triggers federal impact assessment. Gold mines are treated as metal mines for this purpose.

Cross that line, and the timeline changes dramatically. A triggered federal review can run three to eight or more years depending on complexity, which would place any sub-two-year target permanently out of reach.

Federal impact assessment timelines have run considerably longer than provincial ones in recent Canadian cases, with major nickel and base-metal projects demonstrating how a triggered federal review reshapes a project’s entire capital planning horizon.

Fenn-Gib is structured to remain below the 5,000 t/day threshold. That keeps jurisdiction strictly provincial and makes 1P1P the applicable framework, a positioning the January 2026 PFS confirmed by identifying the Provincial Class EA pathway.

The current threshold is higher than it once was. Earlier regulations cited figures as low as 3,000 t/day for metal mines, and 2018 project-list consultations referenced triggers as low as 600 t/day for gold mines. The bar for mandatory federal review has risen over time.

The residual risk investors should understand Even below the threshold, the federal Minister retains discretionary power under Section 9 of the IAA to designate a project for review on a case-by-case basis. Careful project design and conduct can mitigate this risk. They cannot eliminate it.

The threshold is not a passive line Mayfair happened to stay under. It is a design constraint that shapes production rate, capital intensity, and ultimately the economic model of the mine. The permitting strategy and the project economics are not separable decisions.

For anyone evaluating development-stage projects across Canada, this threshold is a binary that fundamentally determines whether a sub-two-year permitting path is even possible. Knowing where Fenn-Gib sits, and why, is essential context for judging the credibility of its 2028 construction target.

First Nations consultation as a parallel critical path, not an afterthought

It is tempting to file Indigenous consultation under compliance, a box to be ticked while permits move. That mental model is not just incomplete. It is a legal liability, and understanding why reframes the entire timeline.

The constitutional framework and the legal risk

Section 35 of the Constitution Act, 1982 recognises and affirms existing Aboriginal and treaty rights. When proposed activities may adversely affect those rights, the Crown carries a constitutional duty to consult and, where appropriate, accommodate.

Legal commentators are specific about the danger. When consultation is treated as a parallel administrative track conducted while permits are issued, rather than integrated into the actual decision-making, proponents face a heightened risk of quashed decisions, injunctions, and adversarial conflict.

That risk is not theoretical. Quashed decisions and injunctions have derailed projects far further along than Fenn-Gib, which is why the informal timeline compression 1P1P offers is only achievable if consultation runs in genuine parallel with permitting, not behind it.

Duty to consult case law has repeatedly confirmed that procedural compliance alone does not satisfy the constitutional standard, with appellate courts quashing approvals where the process was found to be a form rather than a substantive engagement with affected communities.

Precedent shows what substantive engagement looks like and the outcomes it produces.

• Frontier Lithium (PAK Project): Advancing under 1P1P with an anticipated 24-month timeline, supported by formal process agreements with Deer Lake First Nation and Sandy Lake First Nation.
• First Mining Gold (Springpole): Ran an Anishinaabe-led Impact Assessment that let communities define the assessment’s scope, with agreements reached covering Cat Lake, Lac Seul, and Slate Falls First Nations.
• Wawa Gold Project: Demonstrated that disciplined process optimisation and proactive relationship management can independently cut a permitting schedule for bulk sampling by 12 months.

What a formal agreement with Apitipi Anicinapek Nation would signal

The Fenn-Gib site sits within the territory of the Apitipi Anicinapek Nation, whose community is located 15 to 20 kilometres from the project. Mayfair frames this relationship as a required partnership, not stakeholder management. Additional communities located 60 to 100 kilometres away are also part of the broader consultation.

A formal agreement is targeted for Q4 2026 or Q1 2027, though Mayfair has stated the relationship will not be rushed and is being treated as a long-term partnership. In practical terms, that means the target is a genuine aspiration rather than a hard deadline being forced against the community’s pace.

A signed agreement would confirm the consultation track is not a lagging risk to the permitting timeline. For you, assessing the credibility of an 18-24 month forecast, the quality of engagement is as important as the technical readiness of the application. A well-prepared permit submission paired with weak community relationships carries legal exposure that can erase the timeline advantage entirely.

What the 2028 construction decision actually depends on

Pull the threads together and the 2028 construction target resolves into three parallel critical paths, each with its own clock and its own risk profile.

The first is formal 1P1P designation. Mayfair submitted its application in July-August 2026, targeting the fourth formal designation, and a decision is still pending. The 18-24 month permitting clock only starts once designation is confirmed.

The second is the Indigenous agreement, targeted for Q4 2026 or Q1 2027. The third is the residual federal risk under Section 9, which no amount of preparation removes entirely.

Mayfair has built genuine structural advantages into its position: more than three years of baseline data, confirmed infrastructure suitability from condemnation drilling, provincial-only jurisdiction, and an experienced EA lead. What remains uncertain sits largely outside its control.

For a 4.3-million-ounce resource targeting construction in 2028 and initial production in 2030, the specific signals to monitor over the next 6-12 months are clear.

1. Designation confirmation: Whether Mayfair becomes the fourth formally designated project, which starts the permitting clock.
2. The Apitipi Anicinapek Nation agreement: Whether a formal agreement is executed near the Q4 2026 / Q1 2027 target.
3. Absence of a Section 9 notice: Whether the federal Minister leaves the project in provincial jurisdiction.

Those three signals separate execution risk from regulatory and political risk, and that distinction is what you are actually assessing.

Ontario mining risk evaluation frameworks typically weight regulatory risk, geological risk, and community relationship risk separately, and the 1P1P case study shows why regulatory risk and community relationship risk are not independent variables but interact across the same permitting timeline.

Reading the Fenn-Gib case as a template, not a guarantee

Strip away the company-specific detail and Fenn-Gib becomes something more useful than a single project story. It is a worked example of what preparation must look like for 1P1P’s speed to be real, and that makes it a transferable framework for evaluating any future claim on the framework.

Three structural conditions made Fenn-Gib an eligible applicant, and none of them can be created at application time.

• Years of pre-existing environmental baseline data, accumulated well before the framework existed.
• A project design substantially finalised before application, with redesign risk closed out through condemnation drilling.
• A federal threshold deliberately managed to keep jurisdiction provincial.

The broader reform environment carries legitimate criticism worth holding alongside the optimism. Legal and Indigenous-rights commentators warn that compressing timelines risks turning the constitutional duty to consult into a procedural box-checking exercise. On the federal side, debate continues over whether the raised 5,000 t/day threshold leaves too many significant projects exempt from mandatory assessment.

So the framework is a genuine structural innovation with real conditions of use, not a blanket accelerant available to every project. Its stated target of at least a 50% reduction in review timelines remains a target, not yet a demonstrated outcome at scale.

If Fenn-Gib achieves designation and the 18-24 month timeline holds, it becomes the clearest published evidence that 1P1P delivers what it promises. If delays emerge, the precise point of failure will tell the industry more about the framework’s limits than any proponent’s projection.

Apply those three conditions as your checklist, and you will be better placed to tell genuine permitting acceleration from regulatory optimism dressed as strategy.
