Montreal-Trudeau International Airport (YUL) handles over 20 million passengers annually, and parking is one of the biggest hidden costs of flying. On-site lots managed by ADM (Aéroports de Montréal) are convenient but expensive. Off-airport lots along Boulevard de la Côte-de-Liesse offer the same airport access at a fraction of the price. Here's how they compare across every factor that matters.
Price Comparison
This is the primary reason travellers choose off-site parking. The price gap is significant, especially for trips longer than 3 days.
| Duration | On-Site (ADM) | Off-Site (MyAirportParking) | You Save |
|---|---|---|---|
| 1 day | $25 - $32 | $8 - $15 | up to 70% |
| 3 days | $75 - $96 | $24 - $45 | up to 68% |
| 1 week | $150 - $190 | $56 - $105 | up to 63% |
| 2 weeks | $300 - $380 | $112 - $210 | up to 63% |
Feature-by-Feature Comparison

When On-Site Parking Makes Sense
On-site parking at YUL isn't always the wrong choice. It's worth the premium in these situations:
- Very short trips (under 24 hours): The cost difference is smallest for 1-day trips, and walking directly to the terminal saves 15-20 minutes vs waiting for a shuttle.
- Red-eye or very early flights: If you're departing before 5 AM, shuttle schedules at off-site lots may not align with your timing. On-site parking is always accessible.
- Heavy luggage or accessibility needs: The covered walkway from P4/P5 to the terminal is flat and weather-protected. This matters during Montreal's winter months (November through March).
- EV drivers who need charging: ADM's P4/P5 parkades have ChargePoint stations. Off-site EV charging is limited but growing.
- Last-minute trips: If you haven't booked in advance and off-site lots are full, on-site parking is always available (no reservation required for Eco lots).
When Off-Site Parking is the Better Choice
For most travellers, off-site parking wins on value. It's the better option when:
- Your trip is 3+ days: The savings compound quickly. A 7-day trip saves $95-135 compared to on-site, enough to cover a nice dinner in your destination city.
- You're travelling during peak periods: March Break, summer (June-August), and the December holidays see the highest on-site rates and the longest lot waits. Off-site lots with advance booking guarantee your spot.
- You want cancellation flexibility: Life happens. Off-site bookings through MyAirportParking include free cancellation up to 48 hours out. On-site Eco lots don't offer reservations at all.
- You have a larger vehicle: On-site rates are the same for all vehicles, but off-site lots charge per vehicle type. If you're parking a sedan, off-site rates start as low as $8/day — well below the on-site floor of $25.
- You value transparency: Off-site bookings show the exact total upfront (rates + taxes + deposit). On-site parking is pay-on-exit with no upfront price guarantee.
The Verdict
For trips of 3 days or longer, off-site parking near YUL saves $50-170+ compared to on-site. The 3-8 minute shuttle ride is the only trade-off — and for most travellers, that's a small price for savings of 60-70%. On-site parking remains a solid choice for short stays, early flights, or travellers who prioritize the covered walkway and EV charging.
Getting to Off-Site Parking Lots Near YUL
Most off-airport parking lots near Montreal-Trudeau are clustered along two main roads:
- Boulevard de la Côte-de-Liesse: The primary corridor for off-site lots. 1-3 km from the terminal, accessible directly from Highway 520 (Autoroute de la Côte-de-Liesse) and Highway 40 (Trans-Canada).
- Chemin de la Côte-de-Liesse / Michel-Jasmin: Secondary area slightly further from the terminal. Lots here tend to have the lowest rates.
From downtown Montreal: Take Highway 720 West to Highway 20 West (Autoroute du Souvenir), exit at Côte-de-Liesse. Total drive: approximately 20 minutes without traffic, 30-45 minutes during rush hour.
From the South Shore (Brossard/Longueuil): Take the Champlain Bridge or Samuel De Champlain Bridge to Highway 15 North, then Highway 20 West toward the airport. Exit at Côte-de-Liesse. Total drive: 25-40 minutes.
From Laval: Take Highway 15 South to Highway 40 West (Trans-Canada), exit at Côte-de-Liesse Boulevard. Total drive: 20-35 minutes.

Peak Seasons at YUL: When to Book Early
Montreal-Trudeau handles seasonal traffic spikes that affect both on-site availability and off-site lot capacity:

- December holidays (Dec 18 - Jan 3): The busiest period of the year. Both on-site and off-site lots reach capacity. Book 10-14 days ahead for guaranteed availability.
- Thanksgiving weekend (early October): Moderate spike. Book 3-5 days ahead.
- Construction Holidays (last 2 weeks of July): Quebec's construction industry vacation period. Airport traffic peaks. Book 5-7 days ahead.
