The federal government has warned Ontario that it’s willing to stall Highway 413 if the province doesn’t do a better job of consulting First Nations, internal documents show.

Highway 413, which would loop around suburbs in the northwestern Greater Toronto Area, is a signature project for Premier Doug Ford’s Progressive Conservatives. But the highway hasn’t moved forward very much since May 2021, when the federal government decided to step in and subject it to another layer of review. 

As part of that review, Ontario has spent the last year working on a preliminary report that the Impact Assessment Agency of Canada, which oversees the process, will use to decide whether a full-blown federal impact assessment is necessary. Feedback from Indigenous communities is one of the factors the federal agency must consider. 

Early on in the process, some of that feedback raised red flags, new documents obtained by The Narwhal show. Two First Nations, Mississaugas of the Credit and Six Nations of the Grand River, have expressed dissatisfaction with the level of consultation so far. Ontario’s transportation ministry had also, as of June 2021, failed to incorporate traditional Indigenous Knowledge into highway plans or to consider the impact of the project on Indigenous communities, two other federal requirements.

Mississaugas of the Credit First Nation has long lived on a territory stretching from the Rouge Valley, at the east end of what is now Toronto, to the eastern shore of Lake Erie and the Niagara area. The nation, which has a reserve south of Brantford, Ont., told the Impact Assessment Agency that its dealings with Ontario on Highway 413 “felt more like information sharing than a two way dialogue,” according to minutes from a June 2021 meeting between the Ontario Ministry of Transportation and the agency.

Six Nations of the Grand River “noted similar concerns… regarding engagement to date,” the minutes said. The community’s territory is on land surrounding the Grand River west of Toronto, an area of land known as the Haldimand Tract, which the Crown granted to Six Nations in 1784. Six Nations also has a reserve south of Brantford.

Those “consultation issues” may be enough grounds for Ottawa to launch a full federal intervention, the agency warned, according to the minutes. That would subject Highway 413 to a more rigorous process that could delay it for years to come. 

If the province wants to avoid a full impact assessment, the agency would want to get the “impression from the Indigenous Groups that they feel that their concerns will be addressed,” the minutes read.

“There is no expectation that every problem is resolved… However, it needs to be clear to [the Impact Assessment Agency of Canada] that there is a good relationship with stakeholders and Indigenous Groups in order to resolve issues moving forward.”

A flowchart. TITLE: The federal impact assessment process The public sparks the impact assessment process by asking the federal environment minister to look into the project. In the case of Highway 413, the request was made by Ecojustice in Feb. 2021 on behalf of a coalition of environmental groups. After that, the minister has 90 days to hear feedback from the public and make a decision. In May 2021, then-federal environment minister Jonathan Wilkinson decided to designate Highway 413 under the Impact Assessment Act, which starts the impact assessment process. Highway 413 is currently in the pre-planning stages of the impact assessment. During this time, the Ontario government is responsible for preparing a report called an “initial project description” — once that’s submitted, the formal planning phase begins. Both levels of the government also must consult Indigenous communities and the public throughout the process. A) After reviewing the initial project description for Highway 413, the Impact Assessment Agency could conclude that a full review of the project isn’t actually necessary. That would end the federal impact assessment process and allow Ontario to move forward on its own. B) The Impact Assessment Agency could find that, after reading over the initial project description, there are issues with Highway 413 that should be addressed through a full review. 5 (Leading from 4): If the Impact Assessment Agency decides to give Highway 413 a full review, the process would go through several more stages that could take years. At the end, the minister of the environment would decide whether the project can go ahead, and if so, whether that has any conditions.

Concerns about the Ontario government’s consultation process persisted until at least last fall, when the Impact Assessment Agency again critiqued the province’s engagement with Indigenous communities. 

In October 2021, the province submitted a draft of its preliminary report to the Impact Assessment Agency, which was obtained by The Narwhal through access to information legislation. In feedback for the Ontario government contained in that access to information request, the Impact Assessment Agency said the province’s work failed to include “specific concerns” raised by Indigenous communities and didn’t demonstrate “how their input was considered in the design” of Highway 413. Both things are required under federal rules.

Mississaugas of the Credit First Nation and Six Nations of the Grand River did not answer questions from The Narwhal by deadline.

In an emailed statement, the Impact Assessment Agency of Canada did not dispute the province’s minutes of the meeting, but said it can’t determine whether Ontario has resolved issues with Highway 413 until the Ministry of Transportation submits a final report.

Dakota Brasier, a spokesperson for Ontario Transportation Minister Caroline Mulroney, did not answer when asked what the province has done since 2021 to allay concerns from the First Nations and the Impact Assessment Agency. In an email, Brasier said the province is continuing to work on its final report.

“This is a complex process, and we are working diligently to meet the requirements so that we can deliver on our plan to build Highway 413 as soon as possible,” Brasier said.

Federal government has also raised red flags about species at risk around Highway 413 

Highway 413, also called the GTA West Corridor, would run a 60-kilometre route between the Toronto suburbs of Vaughan and Milton. Opposition to the project has mainly centred on its environmental impact. 

The highway would cut through Ontario’s protected Greenbelt and prime farmland. New highways tend to attract more traffic, which contributes to carbon emissions that fuel climate change. The highway would also go over 95 waterways, three conservation properties, five aquifers and 65 archaeological sites, according to documents reported by The Narwhal in June. 

The same month, reporting by The Narwhal and the Toronto Star showed the province has quietly confirmed that 11 species at risk are living along the 413’s route. Two of those species — the western chorus frog and the rapids clubtail dragonfly — are federally-protected but not included in Ontario’s endangered species law, part of then-federal environment minister Jonathan Wilkinson’s rationale for intervening in the project in the first place. (Wilkinson also had concerns about a third species, the red-headed woodpecker, which the Ontario government hasn’t yet located along the highway’s path.) 

The presence of the western chorus frog and the rapids clubtail already raises questions about whether Ottawa might be compelled to conduct a full assessment of the project. The problems with Indigenous consultation may also present a significant stumbling block for the 413, which is already behind the timeline the Ford government had pushed for. In 2020, Ontario proposed to begin early construction work before finishing its own environmental assessment, which was expected at the time to be done in 2022

Another problem raised in the June 2021 meeting, according to the Ministry of Transportation’s agenda: by its own admission, the provincial government had not done work by that point to fulfill federal requirements to incorporate traditional Indigenous knowledge into its plans, and consider how Highway 413 might impact Indigenous communities.

“No traditional knowledge has been provided/gathered to date and no consideration of how the Indigenous communities may use the land in the future,” the ministry’s meeting agenda said. 

In her email, Brasier did not directly answer when asked whether Ontario is concerned that consultation issues could hold up Highway 413. 

“To be clear – the principal elements of concern raised about this project by the federal government specifically relate to the potential adverse effects on the western chorus frog, red-headed woodpecker and rapids clubtail dragonfly,” Brasier said.

Highway 413 isn’t the first Ontario government project to stir concerns around consultation with Indigenous communities. In the Far North, Neskantaga First Nation has said Ontario’s consultation on proposals to build roads to the Ring of Fire region are “inadequate.” And in 2020, Chapleau Cree, Missanabie Cree and Brunswick House First Nations filed a lawsuit alleging the Ontario government didn’t properly consult them on its plans to manage forests in their territories. 

Canadian courts have affirmed again and again that governments have the duty to consult Indigenous people on projects affecting their rights or on their territories. But it would be very unusual for a government acting on its own to put the brakes on a project over Indigenous consultation concerns. And the federal government’s impact assessment law is still fairly new, so there’s not a lot of precedent for what happens next. 

In its email, the Impact Assessment Agency confirmed that it has not received another draft of Ontario’s report. It’s not clear how long it might take for the province to file a final version.

Another year of keeping a close watch
Here at The Narwhal, we don’t use profit, awards or pageviews to measure success. The thing that matters most is real-world impact — evidence that our reporting influenced citizens to hold power to account and pushed policymakers to do better.

And in 2024, our stories were raised in parliaments across the country and cited by citizens in their petitions and letters to politicians.

In Alberta, our reporting revealed Premier Danielle Smith made false statements about the controversial renewables pause. In Manitoba, we proved that officials failed to formally inspect a leaky pipeline for years. And our investigations on a leaked recording of TC Energy executives were called “the most important Canadian political story of the year.”

As the year draws to a close, we’d like to thank you for paying attention. And if you’re able to donate anything at all to help us keep doing this work in 2025 — which will bring a whole lot we can’t predict — thank you so very much.

Will you help us hold the powerful accountable in the year to come by giving what you can today?
