Porter Turns Montreal’s South Shore Into New Air Travel Hub

Porter Airlines is preparing to shift part of Montreal’s air traffic across the St. Lawrence River, using a new terminal at Montreal Metropolitan Airport in Saint-Hubert to transform the city’s South Shore into Canada’s newest travel powerhouse.

A New Terminal Redraws Montreal’s Air Map

The opening of a dedicated Porter Airlines terminal at Montreal Metropolitan Airport, in the Saint-Hubert borough of Longueuil, marks a turning point for the region’s aviation landscape. Publicly available information shows that the facility is being developed through YHU Terminal, a partnership between Porter’s parent company and Macquarie Asset Management, with the goal of bringing full-scale commercial service back to the South Shore for the first time in decades.

Montreal Metropolitan Airport, known by its code YHU, has historically served general aviation and flight training. According to published coverage and corporate reporting, the new terminal is designed as a modern, jet-capable facility tailored to Porter’s expanding Embraer E195-E2 fleet, with capacity for significant passenger growth and an upgraded customer experience compared with the small existing terminal on site.

The project effectively gives Greater Montreal a second passenger airport alongside Montreal Trudeau. While Trudeau remains the region’s primary international gateway and a hub for legacy carriers, the South Shore terminal is positioned to focus on high-frequency domestic and transcontinental routes, relieving pressure on the main airport and offering an alternative for travellers east and south of downtown.

Recent announcements and media advisories indicate that the new terminal is entering its launch phase, with the airport operator inviting media to preview the facility and outlining imminent commercial operations. For airlines and passengers, this signals that YHU is transitioning from a niche airfield into a fully fledged player in Canada’s competitive network of urban airports.

Strategic Location in Canada’s Eastern Triangle

Industry data frequently highlights the Ottawa–Montreal–Toronto corridor as one of Canada’s busiest air and ground travel markets, often referred to as the Eastern Triangle. Montreal’s South Shore sits directly on the Quebec leg of this axis, connected to downtown Montreal by road and public transit, including the Longueuil metro terminus. Supporters of the YHU project argue that positioning a jet terminal here taps into a dense catchment of suburban residents and cross-river commuters who currently rely on Montreal Trudeau or long highway drives.

Transport plans shared by local authorities and airport partners point to the creation of a dedicated METBus link between the new terminal and the Longueuil metro station, with frequent service intended to keep total journey time to central Montreal competitive with surface trips to Trudeau. This focus on connectivity underpins efforts to make YHU a realistic first choice for South Shore residents and a viable alternative for downtown travellers who prefer metro access over highway congestion.

At the regional level, Longueuil’s location gives Porter a springboard into Quebec’s wider population base, including communities along the south side of the St. Lawrence River and key corridors toward Quebec City and Eastern Quebec. Combined with Porter’s existing presence at Montreal Trudeau, the South Shore base allows the airline to serve distinct market segments within the same metropolitan area, mirroring dual-airport strategies seen in other North American cities.

Analysts note that the move also fits a broader trend of secondary airports gaining prominence in large urban regions, especially when paired with new infrastructure and a committed home carrier. In this case, YHU’s transformation is tightly linked to Porter’s growth plans, giving the airport an anchor tenant and a clear role within national air networks from day one.

Porter’s Growth Engine Arrives on the South Shore

Porter’s expansion over the past three years has been propelled by its Embraer E195-E2 jets, which complement the airline’s established Dash 8 turboprop fleet. Manufacturer disclosures and airline statements show that Porter has rapidly become the largest global operator of the E2 family, using the aircraft to extend its network well beyond its original Toronto Island base into major Canadian, U.S., and leisure markets.

Network updates published in late 2024 and 2025 detail a wave of new routes from Toronto Pearson, Ottawa, Montreal Trudeau, Hamilton and Vancouver, including services to Western Canada, U.S. cities and sun destinations such as Cancun, Puerto Vallarta, Nassau, Grand Cayman and Liberia in Costa Rica. This growth has positioned Porter as a challenger to Canada’s incumbent carriers on both business and leisure routes, with a strategy built around high cabin standards, complimentary amenities and a focus on mid-size, point-to-point markets.

The Saint-Hubert terminal gives this growth engine a dedicated base in the Montreal area. Aviation analysts and enthusiast commentary suggest that Porter plans to use YHU primarily for domestic and transcontinental routes that do not require on-site customs and immigration facilities, while keeping international and transborder flights at Montreal Trudeau. In practice, that sets the stage for a two-airport strategy in Montreal, with the South Shore handling much of the short and medium haul traffic that feeds Porter’s broader Canadian network.

By anchoring the new terminal, Porter also becomes a central economic actor on the South Shore. Airport development documents and local business coverage point to expectations of new jobs, supplier contracts and travel-related spending in Longueuil and nearby municipalities, reinforcing the perception of YHU as an emerging transportation hub rather than a simple overflow airport.

Competitive Shockwave for Carriers and Travellers

The rise of Montreal’s South Shore as a Porter stronghold carries implications for competitors and consumers across Eastern Canada. Porter’s entry into Western Canada routes from Montreal, for example, has already introduced additional capacity and new fare options on city pairs long dominated by larger carriers. Published route analyses compare these moves to similar competitive shifts in Toronto and Ottawa, where Porter’s presence has pushed rivals to adjust schedules, pricing and product offerings.

With the YHU terminal coming online, industry observers expect a new round of competition focused on convenience. For many travellers living on the South Shore or in communities southeast of Montreal, Saint-Hubert may offer shorter access times and lower ground transport costs than Montreal Trudeau. If Porter layers in frequent service to Toronto, Ottawa and Western Canada from YHU, the result could be a powerful combination of time savings and price competition that reshapes booking patterns across the region.

The new base also enhances Porter’s ability to build banked connections across its network. Reports mapping the airline’s schedule evolution show that Ottawa and Toronto Pearson already function as key connecting nodes. Adding Montreal Metropolitan Airport to this mix, with carefully timed flights to major domestic destinations, would give the carrier another tool for capturing connecting traffic that previously defaulted to larger legacy hubs.

For leisure travellers, especially those heading to Western Canada or sun destinations via connections, the shift could translate into more choices and potentially smoother itineraries. A South Shore resident, for instance, could reach Calgary, Vancouver or onward vacation markets with a short bus ride to YHU and a single connection through another Porter hub, bypassing the longer trek to Trudeau altogether.

South Shore Airport Project Signals Wider Urban Transformation

Beyond aviation, the redevelopment of Montreal Metropolitan Airport is being framed by regional planners and business groups as part of a broader urban shift on the South Shore. The presence of a modern commercial terminal, paired with new transit links and airport-area investments, is expected to raise the profile of Longueuil as a gateway city rather than simply a bedroom community for Montreal.

Municipal planning documents and economic development commentary highlight the potential for airport-adjacent business parks, hospitality projects and logistics operations that leverage the new passenger flows. As Porter and its partners ramp up service from YHU, these secondary effects could help redraw the economic geography of the South Shore, concentrating more jobs and services closer to the airport and metro corridor.

The project arrives at a moment when many Canadian cities are rethinking how airport infrastructure can support regional growth and climate objectives. Porter has emphasized the relative fuel efficiency of the E195-E2 fleet and has published sustainability reporting detailing efforts to reduce emissions per passenger. For South Shore communities, the balance between added air service, noise concerns and environmental performance will likely shape how the new travel hub is perceived over the longer term.

What is clear is that Montreal’s South Shore is no longer merely watching the action across the river. With Porter’s new terminal at Montreal Metropolitan Airport stepping onto the national stage, Longueuil is emerging as a key node in Canada’s air travel network and a testing ground for how secondary airports can reshape urban regions.
