Yes.
In factory built home parlance, generally, a 'mobile' home is built to HUD building codes (which are the same nationwide) and is not considered a permanent residence - often time it stays on wheels even when put in place, and can theoretically be moved at a later date (although they rarely ever are). These are also sometimes referred to as 'trailer houses'. They used to be built very cheaply and were a depreciating asset (think like a car or an RV), but there are higher quality options these days.
A 'modular home' will be built to spec to the local building codes wherever it is being placed (which is usually IRC + whatever peculiarities local government officials have tacked on). They are placed on a permanent foundation, cannot be moved, and are generally treated as equivalent to a site-built home once finished. Again, you can spend a little or a lot on these, some factories will do fully custom designs that would be completely indistinguishable from a high-end site-built home once finished.
Many factories will build either variety, some specialize on one over the other. In rural, higher cost of living areas both varieties are often quite a bit cheaper than a site-built home, both because of the efficiencies and economies of scale a factory can provide, and also because they can be built in an area with lower labor costs and shipped to your land.
In populated, growing urban areas, the cost benefit diminishes a bit because production builders can approximate the benefits a factory has by building 100s of homes in the same neighborhood at the same time.
edit to add: My information pertains to the US, the article references land in Canada. I don't know as much about factory built homes or building codes in Canada.
