On the prairies, “RTM” is part of the vocabulary: a ready-to-move home, built complete in a builder's yard and hauled to your land in one piece. Modular homes arrive built too, so buyers often assume the two are the same thing with different names. They aren't. The differences show up in how the home is certified, how far it can travel, and how big it can be, and depending on your land and your plans, those differences can decide which one fits.
What an RTM Is
An RTM is typically a conventionally framed house, built above grade in a builder's yard, then lifted onto a truck and moved to a permanent foundation, usually within a regional radius of the yard. Because it moves in one piece, the whole house has to fit down a highway at once. RTMs are a well-established option in Saskatchewan and Manitoba, and good yards build good houses.
What a Modular Home Is
A modular home is built as one or more sections in an indoor facility, to CSA A277, the Canadian standard for factory-certified construction, and the 2015 National Building Code. Sections are finished inside the plant, transported individually, and joined on the foundation. Both RTMs and modulars end up as real property on a permanent foundation; the path there is what differs.
Difference 1: Where the Inspection Happens
Under CSA A277, certification happens inside the factory: an independent certification body audits the plant and inspects units as they're built, stage by stage, before walls are closed in. The home arrives on your land already certified to code, which municipalities accept in place of re-opening walls for site inspection. An RTM built in a yard follows the conventional inspection route instead, arranged through the builder and the local authority. Neither approach is wrong; the A277 route simply moves quality control onto a production line where every unit passes the same checkpoints, indoors, in every season.
Difference 2: How Far It Can Travel
A single-piece house is a wide, tall, heavy load, and every kilometre adds cost and constraint, so RTMs usually stay relatively close to the yard that built them. Modular sections are engineered for transport from the start. That's how our buildings reach places a one-piece house realistically can't: we've delivered over winter ice roads to St. Theresa Point First Nation and onto a roadless bush site for NAIT's forestry campus. If your land is remote, access usually decides this question for you.
Difference 3: How Big It Can Get
An RTM is capped by what can move down a road in one piece. A modular home is capped by how many sections you join, which in practice means it isn't capped the way an RTM is. Our residential lineup runs from a 588 sq ft one-bedroom to a 1,358 sq ft three-bedroom built from full-width sections, and commercial projects stack sections into dormitories, classrooms, and multi-family buildings. If your plans include a wide footprint or future additions, sections scale; single pieces don't.
Where They're the Same
- Both sit on a permanent foundation you prepare ahead of delivery.
- Both are treated as real property, financed and insured like a site-built house. (More in our financing guide.)
- Both compress your on-site construction time to weeks instead of months.
The Short Version
If your land is close to a good RTM yard, your floor plan fits a single transportable piece, and the yard's build quality checks out, an RTM can serve you well. If your site is remote, your home is larger than one load, you want factory-certified inspection behind your walls, or your delivery window lands in winter, modular is built for exactly that job. Most homes are manufactured and delivered in roughly 16 weeks, with site work running in parallel, and every quote is free and written. Tell us about your land and we'll give you a straight answer on fit, including when an RTM might genuinely be the better call for you.
