How to Take the Bus from Sainte-Julie to Downtown Montreal in 2024

What's the Best Way to Get from Sainte-Julie to Downtown Montreal by Bus?

The RTL express bus network offers the most direct route from Sainte-Julie to downtown Montreal, with several options depending on where you're starting and how quickly you need to get there. This guide breaks down every route, fare, and transfer point so you can plan your trip without surprises — whether you're commuting daily or heading in for a weekend at the Bell Centre.

Here's the thing: most people assume driving is faster. Sometimes it is. But between parking costs (expect $20–$35 for a full day near Sainte-Catherine Street) and the chronic congestion on the Jacques-Cartier Bridge during rush hour, the bus often wins — especially if your destination is near a metro station.

Which Bus Routes Connect Sainte-Julie to Montreal?

Three main RTL express routes serve Sainte-Julie commuters heading to Montreal: the 420, 401, and 400. Each has distinct stops, schedules, and ideal use cases.

The 420 — Sainte-Julie Direct

This is the workhorse route. The 420 Express Sainte-Julie departs from the Terminus Sainte-Julie (located at 2100 boulevard Armand-Frappier, near the Costco) and runs limited-stop service to the Berri-UQAM metro station in downtown Montreal. Morning departures start at 5:45 AM with buses every 15–20 minutes during peak hours. The last departure from downtown back to Sainte-Julie is 11:30 PM on weekdays.

Travel time? Approximately 45–55 minutes depending on bridge traffic. The 420 uses the Jacques-Cartier Bridge and includes stops at Radisson metro (for connections to the Green Line) before continuing to Berri-UQAM.

The 401 — Via Longueuil

The 401 serves commuters from the northern parts of Sainte-Julie and connects to Longueuil–Université-de-Sherbrooke metro station. From there, you'll transfer to the Yellow Line — a 20-minute ride to downtown. This route makes more local stops in Sainte-Julie (including boulevard des Hauts-Bois and chemin du Lac) before hitting the highway.

The catch? You'll need to transfer. That said, the 401 runs more frequently than the 420 during off-peak hours — every 30 minutes on weekends versus every 60 minutes for the 420.

The 400 — Alternative Express

The 400 Express Varennes–Longueuil–Montréal also serves select stops in eastern Sainte-Julie, particularly near the industrial park off boulevard Marie-Victorin. It's less useful for most residents but worth knowing if you live in that area or work near the Technoparc.

How Much Does the Bus from Sainte-Julie to Montreal Cost?

A single fare on RTL express routes costs $5.25 as of 2024. You'll need an Opus card — paper tickets aren't accepted on express buses. Purchase and reload your Opus at the Terminus Sainte-Julie, Pharmaprix locations on boulevard Armand-Frappier, or any Couche-Tard with a transit terminal.

Worth noting: RTL fares are separate from STM (Montreal) fares. If you're taking the 420 all the way to Berri-UQAM, you're done — one RTL fare covers it. But if you transfer to the metro at Radisson or Longueuil–Université-de-Sherbrooke, you'll need an STM fare ($3.75) for the subway portion. The 420 continues to Berri-UQAM without requiring a metro transfer, which is why most commuters prefer it.

Monthly passes offer savings for regular riders. The RTL monthly pass costs $115.00 and covers unlimited local and express bus travel within the RTL network. For commuters who also use Montreal's metro and bus system frequently, the All Modes monthly pass ($185.00) covers RTL, STM, and evenexo trains — a solid deal if you're crossing multiple transit zones regularly.

That said, occasional riders might prefer the "Occasionnelle" fare card loaded with individual trips. There's no discount for bulk purchases, but it beats fumbling for change or discovering your Opus is empty at 6:45 AM.

Where Are the Main Bus Stops in Sainte-Julie?

The Terminus Sainte-Julie serves as the central hub — and it's where most express routes originate. Located at the intersection of boulevard Armand-Frappier and highway 20, this modern facility includes indoor waiting areas, real-time departure boards, and a park-and-ride lot with 400+ spaces. Parking is free, though it fills by 7:30 AM on weekdays. Arrive earlier if you want a spot close to the terminal building.

Other key stops include:

• Boulevard des Hauts-Bois near rue Léonard — served by the 401, popular with residents of the Domaine de la Cité neighborhood
• Boulevard Marie-Victorin at rue Fernand-Dufour — 400 and 420 stop here, convenient for the Vieux-Sainte-Julie area
• Boulevard de Mortagne at chemin du Lac — 401 access for residents near Parc du Mont-Saint-Bruno
• Rue Principale at boulevard Armand-Frappier — connecting point for local RTL routes to the express terminals

Each stop has a distinctive RTL sign with route numbers and real-time arrival estimates (when the system is working — it glitches during snowstorms). The Terminus offers the most amenities, including washrooms and a Tim Hortons across the street. The other stops? Just shelters. Bring a coat in January.

What Should You Know About Rush Hour and Scheduling?

Rush hour defines the Sainte-Julie-to-Montreal commute. Morning peak runs 6:00–9:00 AM toward Montreal; evening peak runs 3:30–6:30 PM toward Sainte-Julie. During these windows, the 420 runs every 15 minutes and often fills to capacity — especially the 7:15 and 7:30 AM departures.

Here's the thing about the Jacques-Cartier Bridge: it's unpredictable. A clear run takes 12 minutes from the bridge foot to the Radisson metro area. Add an accident or construction (common from May through October), and that stretches to 35 minutes. The 420 and 400 use dedicated bus priority lanes on the bridge approach, which helps — but doesn't eliminate — these delays.

Weekend service is reduced. The 420 runs roughly every 60–90 minutes on Saturdays and Sundays, with no service after 10:00 PM. If you're planning a night out in Montreal, check the last return time carefully or prepare for a costly Uber — typically $45–$65 back to Sainte-Julie after midnight.

Real-time tracking is available through the RTL website and the Chrono app (the official RTL mobile application). Chrono shows bus positions on a map and can send alerts for delays. It's not perfect — buses sometimes disappear from GPS tracking in the tunnel — but it's better than standing in the cold wondering.

Is Taking the Bus from Sainte-Julie to Montreal Worth It?

For daily commuters working near Berri-UQAM, Place-des-Arts, or the Old Port, the 420 express offers a reasonable balance of cost and convenience. You'll avoid downtown parking fees, bridge tolls (there are none, but the psychological toll of traffic is real), and the wear on your vehicle. The ride itself — assuming you get a seat — offers time to read, catch up on emails, or simply stare out the window at the Saint Lawrence River as you cross the bridge.

The downsides? You're on their schedule. Miss the 7:15 AM bus and the next might be 20 minutes away — or full. Winter weather disrupts service more than RTL admits publicly. And if your Montreal destination isn't near a metro station, you'll be adding walking time or an STM bus transfer to your journey.

Many Sainte-Julie residents adopt a hybrid approach: drive to the Terminus, park free, and take the express bus. Others bike to the terminal in warmer months — secure bike racks are available. A few hardy souls bike all the way to Montreal via the Route Verte cycling network, but that's a story for a different post.

Antoine's honest take? Try the 420 for a week before committing to a monthly pass. The 6:45 AM departure is rarely crowded and gets you to Berri-UQAM by 7:30 — perfect for an 8:00 AM start with time for coffee. Avoid the 7:30 AM bus unless you enjoy standing for 45 minutes while holding a stranger's backpack. And always, always check the RTL Twitter account (@RTL_QC) before leaving the house during snow season. Some mornings, the bridge is a parking lot and everyone's better off working from home anyway.
