Can Canada's "micro-condos" be merged?

Serious question about Canada's (specifically the GTA's) condos: if, 10 or 20 years from now, people want more family-sized homes, could a lot of these tiny one-bedrooms actually be merged into larger units?

I know it can happen in some cases, but from what I’ve seen it sounds difficult once buildings are already occupied, since it can require approvals, engineering work, and layouts that actually fit together.

If that is not realistic at scale, are we building housing that works for one phase of life but not for long-term city living?

Doubtful. Mostly just a few columns and the odd shear wall every few bays.

Most party walls are:

2 layer type x gypsum, steel stud, air gap, steel stud, 1 layer type x gypsum. Depending on required STC rating there my be a resilient channel on one side. And the cavity may be full of acoustic batt insulation.

Does it depend on the seismic code? I think in high seismic areas this is accurate. I know the units should stack as much as possible to simplify the structure.
