What We Learned Capturing 2 Million Square Feet of Toronto Commercial Real Estate
By Jonas Lood, Lightbound 3D | October 2024 (updated May 2026)
Over the course of 2024, Lightbound 3D scanned and documented more than 2 million square feet of commercial real estate across Toronto — working alongside property owners, operators, and flex-space providers building out office portfolios at speed. Twelve months of fieldwork across more than 200 commercial floors gave us a clear view of what works, what breaks, and where the real money gets lost in how Toronto buildings are documented today.
This is what we learned.
Toronto's commercial buildings run on bad data
The single most consistent finding across our 2024 program: the floor plans landlords hand to tenants are wrong.
We scanned more than 200 commercial floors across the GTA in 2024. Across that dataset, more than 80% of operators were working from drawings that diverged from physical reality by 5–10%. Sometimes more. This isn't an estimate or an industry benchmark — it's what we measured directly, site by site, scan by scan.
The discrepancies showed up in three places that mattered:
Rentable vs. usable square footage. Lease documents reflected one number; the laser scan reflected another. On a 15,000 SF floor at $35/SF gross, a 7% discrepancy is over $36,000 in annual lease cost. Multiplied across a portfolio and a multi-year term, the numbers get serious quickly. We saw individual operators carrying six-figure lease exposure based on plans that nobody had ever ground-truthed.
Demising walls and column locations. Tenants designing fit-outs around plans that misplaced load-bearing elements ended up with redesign costs, change orders, and schedule slippage during construction.
Mechanical and electrical routing. Most legacy floor plans don't show MEP infrastructure at all, and the ones that do are often based on the original design drawings — not the as-built reality after decades of tenant improvements.
The fix isn't complicated, but it does require treating building documentation as something that needs to be captured fresh, not inherited from a PDF the landlord's broker forwarded in 2019.
Design-bid-build doesn't scale
The traditional design-bid-build model — the framework most architecture firms still default to — was designed for one-off custom projects. It works when you have months to coordinate consultants, run bidding rounds, and iterate on a single building.
It doesn't work when you're trying to open 30, 50, or 100 sites in a year.
What we saw in 2024 was operators discovering this the hard way. Project teams spending weeks renegotiating scope with a new architectural team for each location. Bid cycles eating into rollout timelines. The same problems being solved from scratch on every site because the lessons from site #4 weren't being captured in a way that informed site #14.
The operators that scaled successfully treated office build-out as a repeatable product, not a series of bespoke design projects. That meant three things:
A standardized capture process for every site — same scanner, same registration protocol, same deliverable format, regardless of who the design team was downstream.
A documentation library that every project team could reference, so site #14 started with the lessons from sites #1–13 already embedded.
Procurement and design decisions made portfolio-wide rather than project-by-project.
The first 2 million square feet was where this approach got proven out. The next portfolio rollout, for any operator scaling in this market, starts from a fundamentally different position than it would have in 2023.
What BIM actually does at portfolio scale
BIM gets discussed a lot in the AEC industry. In our experience scaling across multiple operators in 2024, the value isn't theoretical — it's measurable in three places.
Speed to lease-up. With an accurate existing-conditions BIM model on day one of a fit-out project, design teams skip 3–6 weeks of measurement, drafting, and verification work. On a fast-rollout program, those weeks compound across every site.
Change order reduction. The single biggest cost overrun on commercial fit-outs comes from discovering site conditions that don't match the documentation. A laser scan and BIM model on file before tendering means contractors bid on accurate scope, not assumptions.
Portfolio intelligence. Once you have BIM models for every site in a portfolio captured to the same standard, comparison becomes possible — floor-plate efficiency, MEP density, lighting load, ceiling height variance. Operations teams start making capital allocation decisions based on data, not vibes.
This is the gap between BIM as a checkbox deliverable and BIM as an operating discipline. Most Toronto operators are still in the first category; the ones scaling fastest have moved to the second.
The BIM+ approach: making models accessible to non-technical stakeholders
There's a problem with how BIM models traditionally get used on commercial projects: only the architects, engineers, and contractors can actually open them. Everyone else on the project team — leasing brokers, asset managers, operations leads, the COO who needs to sign off on the rollout — is locked out by the software.
The result is a familiar pattern. Design decisions get made in Revit. Documentation lives in Revit. But the people making the business decisions are still working from PDFs, screenshots, and second-hand summaries because they don't have Autodesk licenses and shouldn't need them.
Our 2024 program is where we developed what we call the BIM+ approach: pairing every laser-scanned BIM model with a Matterport virtual tour of the same space, captured in the same site visit.
The BIM model gives the design team precision — millimetre-accurate geometry, intelligent objects, full Revit interoperability. The Matterport tour gives every other stakeholder spatial intuition — a walkable, dimensioned 3D environment they can navigate from any browser, on any device, without specialised software.
One source of truth, two interfaces. Technical teams work in the model. Everyone else works in the tour. Both reflect the same physical reality because both came from the same scan.
For multi-site operators in particular, this changed the velocity of decision-making. Leasing teams could walk prospective tenants through a space remotely. Operations leads could plan capital programs from their laptops. The COO could sanity-check a build-out without flying to Toronto. None of that is possible when the only deliverable is an .rvt file.
This is the wedge we built our practice around, and as far as we're aware, Lightbound 3D is the only firm in Toronto delivering both deliverables from a single site capture — which is what makes the BIM+ approach economically viable at portfolio scale.
What's different in 2026
We wrote the first version of this post at the end of 2024. Looking back from mid-2026, two things have shifted that reinforce the original conclusions.
First, the City of Toronto's Energy and Water Reporting Bylaw now requires every building over 50,000 SF to report energy and water usage annually, with the threshold dropping to 10,000 SF by 2027. Building owners without accurate baseline documentation are scrambling. The ones who captured comprehensive scan data in 2024 are reporting from a position of strength. (We've written more on this in How Digital Twins Are Reshaping Commercial Property Management in Toronto.)
Second, AEC labour costs and timelines have continued to tighten. The operators we worked with in 2024 who invested in upfront documentation are running 2026 expansion programs at materially lower cost per square foot than competitors who are still measuring buildings by hand.
The thesis from 2024 — that commercial space documentation needs to be treated as a scalable product, not a per-project deliverable — has only gotten stronger.
Working with Lightbound 3D
If you're managing a portfolio of Toronto commercial properties and the documentation question is on your mind, we can help. Our 2024 program scanned and documented 2 million square feet for operators across the GTA, and we work with property owners, AEC teams, and flex-space providers on programs ranging from single-floor scans to portfolio-wide rollouts.
