Building the north, one module at a time.
Thunder Bay's premier modular home builder, delivering precise construction and disciplined craft across Northern Ontario for over 15 years.
Rooted in the north.
Built for the north.
Founded in Thunder Bay to bring factory-precision construction to Northern Ontario's climate and housing needs — from a small team with big ambitions to a disciplined modular operation serving communities across the north.
Over 15 years of residential and commercial building experience shapes every decision — material, sequencing, and site coordination. We build indoors, so every module ships at the same quality, year-round.
Backed by Ontario.
$1M to scale modular across the north.
The Government of Ontario, through the Northern Ontario Heritage Fund Corporation, is investing $1 million to help ModBox Modular scale up modular home construction in Thunder Bay — increasing capacity to serve First Nations communities and residential clients across the north.

Built indoors.
Built for the north.
Our 25,000 sq ft Thunder Bay plant is purpose-built for modular fabrication — dedicated stations for framing, envelope, finishes, and quality control, with every module passing through structured checkpoints before it leaves.
Because we build indoors, weather never dictates the schedule. Three principles flow from that, and they hold from consultation to final handover.
Climate-controlled build
Every module is fabricated indoors in our 25,000 sq ft plant — consistent quality regardless of weather or season.
Disciplined delivery
Transport, craning, and site coordination staged in sequence — minimizing disruption and accelerating timelines.
Northern-rated envelope
R-24+ insulation, sealed construction, and engineering calibrated for Northern Ontario's extremes of cold, wind, and snow.
