A warehouse rarely runs out of room overnight. Pallet counts creep up month after month until a manager notices the aisles are packed, safety stock has nowhere to go, and the next lease renewal looks a lot more expensive than last year's. Before signing extra square footage, it is worth asking whether the building you already have could hold more.
That question is where an ASRS company comes in. MTLI Group has spent more than 40 years helping Canadian facilities answer it, using automated storage technology instead of a bigger footprint. This guide walks through how the technology works, where it pays off, and what a project actually involves once you bring in a partner.
Signs Your Facility Has Outgrown Its Storage Layout
A few patterns tend to show up before a facility formally decides it needs more capacity. Forklift traffic slows down because aisles are crowded with products that have nowhere better to sit. Staff start stacking pallets in spots never meant for storage, like receiving bays or walkways. Cycle counts take longer because inventory is scattered across overflow zones instead of an organized system.
None of these problems point to a labor issue. They point to a layout that has reached its limit. Following warehouse design best practices helps identify whether your facility layout is simply misaligned with your throughput, or if you genuinely need to add capacity. Once a facility hits that ceiling, the two realistic paths forward are leasing or building more space or finding a way to use the existing building more efficiently. Automated storage falls into the second category, and it often costs less time and money than alternatives.
Breaking Down What Automated Storage and Retrieval Actually Involves
ASRS stands for Automated Storage and Retrieval System, a setup where cranes, shuttles, or robotic carriers place and retrieve inventory without a person driving a forklift down the aisle. To understand how these systems function across different facility types, our detailed guide on what is an ASRS provides a comprehensive overview of the technology's capabilities. Because nobody needs room to steer or see around a load, the racking can sit closer together and climb higher than a manual system would ever allow.
That shift, tighter spacing paired with greater height, is the mechanism behind most of the capacity gains a facility sees after installation. A building that once stored pallets across a wide, shallow footprint can hold noticeably more inventory using the same four walls. Every storage slot is also tracked by software rather than a paper log, which tends to improve accuracy alongside density.
ASRS Formats at a Glance
Automated storage is not one product. The table below breaks down the main formats and where each tends to fit best.
| Format | What It Handles | Typical Use |
|---|---|---|
| Unit-load cranes | Full pallets, moved by automated cranes in tall, narrow racking | Bulk pallet storage, cold storage, buffer stock |
| Mini-load cranes | Totes or cartons instead of full pallets | Case picking, parts distribution, e-commerce |
| Shuttle systems | Robotic carriers that move within a level and feed a central lift | Operations with frequent, high-volume picks |
| Vertical lift units | Enclosed towers that bring stored trays down to an operator | Small parts, tool storage, low-footprint sites |
Many facilities run more than one format at once, pairing unit-load cranes for bulk storage with a shuttle system for the SKUs that move fastest. For facilities still evaluating alternatives, in-depth ASRS explanations help clarify which systems best match your operation's unique profile.
The Math Behind Vertical Storage Gains
The capacity increase from ASRS comes down to a few measurable factors rather than a general promise of "more space." Aisle width shrinks from roughly ten to thirteen feet, which a forklift needs to turn, down to as little as three or four feet for a crane or shuttle. Storage height climbs well past what a reach truck can safely serve, since no operator needs a clear sightline at forty or fifty feet up.
Multiply narrower aisles by taller racking and the same building footprint can hold considerably more product than it did under manual operation. The exact multiplier depends on ceiling height, current aisle spacing, and how much airspace above existing racking sits unused, which is usually more than facility managers expect once it gets measured. For a deeper dive into these gains, understanding high-density storage solutions clarifies how every inch of vertical and horizontal space converts into tangible inventory capacity.
Market Pressure Pushing Facilities to Rethink Layout
Two trends explain why more Canadian operations are looking at automated storage now rather than waiting. Online retail has kept climbing and Statistics Canada reported that Canadian retailers closed out 2025 with $837.2 billion in total sales, a 4.0 percent increase over 2024, with online purchases making up roughly 6 percent of that figure through most of the year. More online orders generally mean more SKUs and more safety stock sitting somewhere.
At the same time, logistics and material handling technology has become one of the most widely adopted categories of advanced technology in Canada. Statistics Canada found that advanced logistics technologies, which include material handling systems like ASRS, were adopted by more than 40 percent of surveyed enterprises, with wholesale trade leading at 50.8 percent. Facilities that have not yet automated storage are increasingly the exception rather than the rule in sectors carrying heavy inventory loads.
Racking Versus Robotics: Where the Numbers Diverge
Comparing conventional racking against automated storage on paper helps clarify which approach fits a given facility.
| Consideration | Selective Racking | Automated Storage |
|---|---|---|
| Aisle clearance | 10 to 13 feet | 3 to 5 feet |
| Usable storage height | Roughly 30 to 40 feet | Can exceed 100 feet |
| Inventory tracking | Manual scanning at put-away | Recorded automatically by the system |
| Staff involvement per movement | One operator per pallet moved | Staff oversee the system rather than drive it |
| Upfront investment | Lower | Higher, offset over time by space savings |
| Where it fits best | Lower SKU counts, slower turnover | High density needs, fast or high-value inventory |
Few facilities pick one option exclusively. Many keep different types of pallet racking for slower-moving stock and automate the zones under the most pressure. This hybrid approach balances capital expenditure with operational efficiency.
The Hidden Scope Most ASRS Quotes Leave Out
Equipment cost is only part of an ASRS project. Taller, rack-supported structures usually call for structural engineering and construction work to reinforce foundations or modify the building envelope. Some sites need a taller roof line or upgraded flooring before automated storage can go in at all, and that work rarely shows up on a basic equipment quote.
A vendor selling only the cranes or shuttles typically leaves the buyer to find separate firms for that construction and engineering work. An ASRS company that folds structural design, construction, and integration with existing storage racking into one contract removes a layer of coordination that otherwise falls on the facility's own team.
Matching ASRS to Your Operation Type
Certain operations see a faster return than others. E-commerce fulfillment sites with hundreds or thousands of active SKUs benefit heavily from mini-load or shuttle formats, since case picking speed drives most of their labor cost. Organizations pursuing automation for e-commerce fulfillment often experience dramatic improvements in pick rates and order accuracy. Cold storage facilities gain a different kind of advantage: fewer staff spending long shifts in low-temperature zones, which reduces both payroll pressure and injury risk in a demanding environment.
Manufacturers holding large volumes of raw material or finished goods often use unit-load cranes to store buffer stock without expanding the plant. Operations with an ASRS company are steady, predictable distribution volume also tend to reach payback faster than sites with sharp seasonal swings, since the system runs closer to capacity year-round. Understanding how to reduce warehouse labor costs through automation helps facilities quantify the financial case for their specific operation before committing to a project.
From First Walkthrough to Full Commissioning
An ASRS company project generally follows a consistent path, whatever the facility type.
- Site walkthrough. Engineers measure ceiling height, floor loading, and current layout to confirm what the building can realistically support.
- Format selection. The design team recommends unit-load, mini-load, shuttle, or mix, based on SKU profile and required throughput.
- Structural scoping. Any reinforced flooring or building modification gets defined before equipment is ordered.
- Phased installation. Field crews sequence work around live operations, since most sites cannot shut down entirely.
- Commissioning. Staff train on the new system before it takes full order volume.
- Long-term support. A defined maintenance guide for automated facilities keeps the system performing at its designed capacity for years, not just at launch.
Facilities that skip the site walkthrough are the ones most likely to run into costs partway through the build that nobody planned for.
Why Facilities Bring MTLI Group into Capacity Projects
As an ASRS company, MTLI Group keeps structural engineering, construction, controls integration, and installation inside a single project team rather than splitting it across separate vendors. That structure removes the handoff points where most capacity projects lose time or budget.
Facilities can review our project portfolio across cold storage, manufacturing, and distribution sites to see how this approach has played out elsewhere in Canada. Every build also includes a maintenance plan from day one, so the system keeps delivering its designed density well past the ribbon cutting.
Start Mapping Your ASRS Company Options
Extra storage capacity does not have to mean a bigger building. In many cases, the space already sitting above existing racking is enough to solve the problem, provided the right system and structural plan are in place. When you're ready to explore whether an ASRS company is the right fit, our guide to ASRS installation services walks through what a full project scope looks like and how the timeline unfolds.
