Wall spray foam insulation in Wetaskiwin is the one town on this site where the wall is worth a serious conversation rather than a deflection, because on a stock this old the cavity genuinely may contain nothing.
A cavity that could hold almost anything
On the oldest Wetaskiwin houses the wall may be entirely empty, or filled with something a previous owner poured in, or packed with material that has settled to the bottom third and left the top two thirds bare. That is a different situation from a post-1991 house where the cavity is full of batt and there is nowhere for anything to go. It means the wall is genuinely a candidate here, and it also means nobody should quote one without establishing what is actually in it.
Why what is in there decides the method
An empty cavity in a sound wall is one thing. A cavity that is half full of settled material is another, because injecting into it fills the space above the settlement and leaves the compacted material below doing very little, which produces a wall that performs unevenly and is impossible to inspect. That distinction is why a small inspection opening in an unobtrusive place is worth ten minutes before a price rather than after, and it is the difference between a job that works and one that disappoints.
The re-side, which is when this becomes straightforward
The version of wall work that makes sense on an old house is the one that happens when the cladding is coming off anyway. With the sheathing exposed the cavity can be seen, cleared where it needs clearing, and treated continuously including at every junction where an addition meets the original building. On a stock where the siding is reaching the end of its life across the whole town, that opportunity is arriving regularly, and it is worth planning for rather than discovering after the fact.
What the wall will not fix on its own
It is worth saying even on the one page where the wall is a real candidate. A treated wall in a house with an unsealed ceiling plane and an untouched rim joist will disappoint, because those two are moving more air than the wall ever was. The order still runs ceiling and rim joist first on almost every house here. The wall earns its place third, which is considerably higher than it ranks anywhere else on this site.

Can you drill and fill it? Sometimes here, which is unusual. It depends entirely on what is already in the cavity.
