Montréal MET Airport Opens New Terminal With Porter on June 15, 2026

A new passenger terminal at Montréal Metropolitan Airport (MET) is set to open on June 15, 2026, establishing a second commercial airport for the Greater Montréal area with Porter Airlines as its anchor tenant. The facility, located at the site of the former Montréal Saint-Hubert Airport (YHU), will initially focus on domestic routes, aiming to provide travelers with an alternative to the city's primary hub, Montréal–Trudeau International Airport (YUL).

The opening marks a significant expansion for Porter Airlines, which will use the new terminal to establish a secondary hub. This move allows the carrier to increase its peak summer capacity in the Montreal market by a substantial 91%. According to a Porter Airlines press release, the airline will launch 12 coast-to-coast domestic routes from MET within the first week of operations, utilizing its fleet of 132-seat Embraer 195-E2 (E195-E2) jet aircraft. This expansion introduces significant new competition in the Canadian domestic market, particularly for carriers operating out of YUL.

Terminal Infrastructure and Investment

The project is backed by a private investment of over $400 million from YHU Infrastructure Partners, a consortium including Porter Aviation Holdings and Macquarie Asset Management. According to a YHU Infrastructure Partners press release, the new terminal spans 21,000 square meters and features nine boarding gates. It is designed with an annual capacity of 4 million passengers.

Charles Roberge, CEO of YHU Infrastructure Partners, highlighted that the terminal's compact layout is designed for a faster, streamlined passenger experience from curb to gate. This focus on efficiency is a key part of the value proposition for secondary airports. Yanic Roy, CEO of MET, stated the new facility will offer more travel options and increase regional capacity. Echoing this sentiment, Porter Airlines CEO Michael Deluce described the project as an "exceptional private investment" that will benefit the region for generations. The airport's official services and flight options are detailed on the MET - Montréal Metropolitan Airport Official Website.

Industry Impact and Competitive Landscape

The launch of commercial services from MET directly impacts several key stakeholders. For competitors Air Canada and WestJet, Porter's 91% capacity increase represents a significant competitive challenge on domestic routes originating from Montreal. The new airport provides South Shore residents of Greater Montréal a more convenient travel option, potentially saving significant commute time to YUL. However, this expansion has also raised concerns among local community groups regarding increased air traffic and noise pollution, leading to regulatory measures. To mitigate these impacts, Transport Canada and the airport authority have implemented a ban on wide-bodied aircraft and commercial night flights.

For Montréal–Trudeau International Airport, the opening of MET may lead to a loss of some origin-and-destination domestic traffic. However, it also serves to alleviate congestion at the primary hub, which is a common strategic goal in multi-airport systems found in cities like Toronto, New York, and London.

Historical Precedents and Technical Analysis

This development follows a proven strategy for Porter Airlines. In 2006, the airline's launch from a new terminal at Billy Bishop Toronto City Airport (YTZ) successfully established a highly utilized secondary downtown airport for Toronto. The MET project replicates this successful business model, applying the same principles of convenience and efficiency to the Montréal market. The situation also mirrors the March 2019 opening of the commercial terminal at Paine Field (PAE) near Seattle, which was also a privately-funded initiative to create a boutique secondary airport to relieve pressure on a major hub.

This trend of private investment in niche airport infrastructure is a significant development in North American aviation. It allows for targeted capacity increases without relying solely on public funding or the expansion of large, often congested, primary airports. By using modern, efficient aircraft like the Embraer E195-E2, which features quieter Pratt & Whitney GTF engines compared to older generation jets, carriers can better manage the environmental and noise concerns associated with operating from airports located closer to residential areas. The MET project demonstrates a clear trajectory toward decentralized, privately-funded airport systems designed to serve specific market segments.

What Comes Next

The primary milestone for the new terminal is its official opening. According to YHU Infrastructure Partners, the first commercial flights operated by Porter Airlines are confirmed to depart from Montréal Metropolitan Airport on June 15, 2026. The initial launch will see 12 domestic routes activated, with potential for further network expansion as the airport establishes its passenger base.

Why This Matters

The opening of the MET terminal represents more than just new infrastructure; it signals a strategic shift in Canadian aviation towards multi-airport systems in major metropolitan areas. For travelers, it introduces greater choice and convenience, while for the industry, it intensifies domestic competition and validates a model of private investment in targeted airport development. This project serves as a key case study for how secondary airports can be leveraged to enhance regional connectivity and alleviate congestion at primary hubs.
