Why Highway 20 Is Québec's Longest Storage Corridor
Autoroute 20 — the Autoroute Jean-Lesage — is the longest highway in Québec at 585 km, and the 250 km stretch from Longueuil to Lévis is the province's primary South Shore link between its two largest cities. It's also the Trans-Canada Highway. Every day, tens of thousands of commuters, families, and 18-wheelers travel this corridor through suburban neighbourhoods, agricultural heartland, and small-town Québec.
Unlike Highway 15 (a cottage corridor) or Highway 10 (a weekend getaway route), the A-20 serves a different clientele — suburban families moving on July 1st, small businesses storing inventory, students between semesters, and farmers with seasonal equipment. Storage demand here is year-round, with massive spikes during Québec's unique Moving Day. Facilities cluster heavily at both ends of the corridor (Longueuil and Lévis), with a competitive mix of national chains and strong local operators. The middle stretch through Centre-du-Québec is much sparser — and if you're in Lotbinière County, the nearest facility could be a 40-minute drive.
Exit-by-Exit Storage Zones
Longueuil, Boucherville, and Saint-Hubert — Exits 80–98
The South Shore gateway and the most facility-dense zone on the entire corridor, with 10+ facilities within 10 km. National chains — StorageMart, Depotium, Public Storage, U-Haul — compete alongside strong local operators. 1215 Mini-Entrepôts in Boucherville (Exit 93, Rue Nobel) is a family business since 1973, with units from 25 to 200 sq ft, 10-foot ceilings, and outdoor parking for boats, RVs, and snowmobiles starting at $60/month.
Libre Entreposage near Boucherville stands out with individual alarms per unit, extensible units (combine adjacent spaces), and a designed basement level for vehicle storage. Mini-Entrepôts du Tremblay specializes in outdoor vehicle storage on a large fenced, lit lot. StorageMart in Saint-Hubert targets students from nearby Collège Édouard-Montpetit with month-to-month flexible leases.
Expect roughly $60–90/month for a 5x5, $100–160 for a 5x10, and $160–230 for a 10x10 — about 15–25% cheaper than Montréal Island.
Mont-Saint-Hilaire and Beloeil — Exits 105–120
A transitional zone where dense suburbs give way to semi-rural countryside along the Richelieu River. Entreposage DC (less than 1 km from Exit 115) serves this area with radiant concrete floor heating and units in various sizes. They also operate a second location in Saint-Pie. Entreposage Rive Sud at Exit 105 (4207-D Bernard Pilon, Saint-Mathieu-de-Beloeil) is just 15 minutes from Montréal via the tunnel — a convenient stop for South Shore residents heading east.
This zone also draws from Entreposage VIP in Saint-Hyacinthe, which is less a self-storage facility and more a full logistics operation — distribution centre, container receipt, pick and pack, palletizing, and managed warehouse space for businesses.
Saint-Hyacinthe — Exits 130–147
The A-20 bypasses Saint-Hyacinthe, the "Capitale agroalimentaire du Québec" (~56,000 population), but the city is accessible via exits 141–147. Despite being a significant population centre with a CÉGEP and major food processing sector, this zone has surprisingly few dedicated self-storage facilities directly on the corridor. Most residents rely on facilities in Mont-Saint-Hilaire (Exit 115, 30 km west) or Drummondville (Exit 175, 45 km east).
This is a notable gap — a city of 56,000 with agriculture businesses, students, and families, and the nearest highway-adjacent storage is a half-hour drive in either direction.
Drummondville — Exits 175–195
The corridor's midpoint hub and the "Crossroads of Québec" — equidistant from Montréal, Québec City, Sherbrooke, and Trois-Rivières. The A-20/A-55 interchange here makes Drummondville a natural logistics centre, and storage operators have taken notice.
Mini-Entrepôt Drummond is the dominant local player with 300 heated units, 47+ HD cameras, alarms connected to police in each unit, and 24/7/365 access from $85/month. They're very highly rated on Google. Espace 20 — literally named after Exit 185 of the A-20 — offers heated, secure units with flexible contracts. LocZone stands out with 150,000+ sq ft of fenced outdoor terrain for RVs, boats, and trailers, plus 200+ indoor units and trailer rentals. Alpha Entrepôts operates across Drummondville, Cowansville, and Roxton Pond.
For businesses, Entreposage Michel Laplume is a managed warehouse with trucks that drive inside to unload, radiant floor heating, and staff always present — not self-serve.
Pricing here is the most competitive on the corridor: roughly $85–130 for a 5x10, $130–180 for a 10x10.
Sainte-Eulalie, Bécancour, and Nicolet — Exits 210–240
The least dense zone on the entire corridor. After the A-20/A-55 split at Sainte-Eulalie, you enter 70+ km of agricultural heartland with barely 2–3 facilities. Entrepôts St-Célestin (near the Pont Laviolette, 10 minutes from Trois-Rivières) offers a 3,000 sq ft self-service building. Structio Storage near Nicolet offers clean, secure units with 24/7 access and a "pay for the space you use" model. Les Entrepôts RMB in Bécancour rounds out the options.
If you're in this zone, Drummondville (30–40 minutes west) or Lévis (45 minutes east) are your realistic alternatives. This is the longest gap on any major Québec highway corridor — about 70 km with essentially no dedicated self-storage.
Lotbinière and Laurier-Station — Exits 253–285
A rural zone approaching the Québec City metro. Entrepôts Laurier in Laurier-Station is a family business (Martin and Daniel) offering heated, secure units for residential and commercial clients. A U-Haul partner location also operates here.
Between Bécancour and Lévis — a stretch of 70+ km — these are the only options. This is one of the most underserved zones on any major corridor in the province.
Lévis, Saint-Nicolas, and Saint-Romuald — Exits 305–315
The eastern terminus and the second major storage cluster, with 10+ facilities serving Lévis (~149,000 population) and the gateway to Québec City across the Pierre Laporte Bridge.
Accès Entreposage in Saint-Romuald (near A-20 and Boulevard Guillaume-Couture) has 400+ modern units with radiant floor heating and 24/7 access — they've been operating since 2003. Bluebird Self Storage in Saint-Nicolas is a national chain with a premium positioning: transparent 365-day pricing (no introductory rate spikes), monthly billing, and a 7-day satisfaction guarantee. Entreposage Kennedy (since 2006) offers residential, commercial, and indoor vehicle storage with individual alarms per unit, plus seasonal contracts for cars, motorcycles, snowmobiles, and RVs.
Entrepôts Modulo is the most innovative newcomer — they provide a free cube truck for move-in, surprise discounts up to 25% at signing, furnished office/meeting room rentals, and affordable motorcycle winter storage. Mini-Entrepôts Lévis, Mini-Entrepôt Sauvageau, and Espace Québec round out a competitive market with options for every need.
Pricing tracks slightly below Longueuil: roughly $75–90 for a 5x5, $90–140 for a 5x10, $140–200 for a 10x10.
What People Store Along the A-20
Unlike the cottage corridors (A-10, A-15), the A-20 serves year-round suburban and commercial demand, with one enormous seasonal spike:
- July 1st Moving Day: Québec's unique lease cycle — 60–70% of leases end June 30 — creates massive short-term storage demand. Facilities in Longueuil and Lévis fill up weeks in advance. Two-to-four-week gap storage between leases is a huge revenue driver along this corridor.
- Suburban families: Renovation overflow (South Shore housing boom in Boucherville, Sainte-Julie, Lévis), downsizing, seasonal gear — winter tires, ski equipment, patio furniture, BBQs.
- Students: The corridor sits between UQAM/Concordia/McGill (students living on the South Shore), CÉGEP de Drummondville, CÉGEP de Saint-Hyacinthe, and Université Laval (students living in Lévis). Summer storage between semesters drives May–August demand.
- Businesses and contractors: Tool and equipment storage, e-commerce inventory, document archiving, excess office furniture. The South Shore is a major construction and renovation market.
- Agriculture (Centre-du-Québec): Farm equipment, crop-related supplies, food processing equipment around Saint-Hyacinthe.
- Recreational vehicles: Snowmobiles, boats, RVs, motorcycles, and the universal Québec need — winter tire sets (mandatory December 1 to March 15).
Tips for Choosing a Facility on Your Route
- Know your zone — The A-20 is dense at both ends and sparse in the middle. If you're between Saint-Hyacinthe and Bécancour, plan for a 30–45 minute drive to the nearest facility.
- Book early for July 1st — Moving Day fills South Shore and Lévis facilities weeks in advance. If you need short-term gap storage, reserve by mid-June.
- Check for radiant floor heating — Common along this corridor (Entreposage DC, Accès Entreposage, Mini-Entrepôt Drummond, Michel Laplume). Better for stored goods than forced-air systems, especially over Québec's long winters.
- Consider managed warehouse for business — If you're a business storing inventory or equipment, Entreposage Michel Laplume (Drummondville) and Entreposage VIP (Saint-Hyacinthe) offer full logistics services — not just empty units.
- Compare chain vs. local — Chains (StorageMart, Depotium, Bluebird, U-Haul) offer brand consistency and online booking at both ends of the corridor. Local operators (Mini-Entrepôt Drummond, Accès Entreposage, Entrepôts Modulo) often have better pricing, unique services, and stronger community reputations.
