Because of the whole standards situation north america has a (like always) oligopoly problem. Canada is even worse because 3 or 4 big companies for example have 90% of the market in Ontario. Even if the building is not big, you basically have to install the same elevator of a skyscraper and the same big company of the skyscraper will be the one doing it.
Europe has a lot of small companies because they are allowed to have smaller and simpler elevators. Sometimes you can find local companies in a 50k people town.
Obviously a 1x1m elevator in a 4 floors building from a small local company in europe has very low costs compared to a skyscraper in Toronto with a north america-standard (big) elevator.
So yes the 10x is an extreme based on the cheapest in europe vs the expensive here but the problem is that we are not allowed here to have the cheaper one. Because even if your building is really small you will need to use the same big company with the same big elevator. And this is how you get the 10x when you consider the extremes. Because we don't have local small companies working with small buildings.

This is not at all how Elevator specc'ing works in building construction.
And I'm not really sure where you got that notion from.
The elevators specc'ed for a particular bulding will be based on the calculated required load and travel times based on the building's expected occupancy - and the building's desing and structure will be partially based around these numbers.
Which means, you're not going to get a bigger elevator than is necessary or required simply because the elevator company providing them only provides that size of elevator.
Mostly because your building's core will not be designed to handle a bigger elevator cabin (or bigger elevator cabins) than they need. That's an uneccessary cost if you don't need it.
You get all this information beforehand, as you're designing it and while working with Structural to determing the size of the core and what's necessary.
The point is that you will end up with what is exactly the size and number of elevators you need with the required load carrying capacity cabin sizes to reduce wait times.
And in light of this, most elevator companies - even here in North America - provide a wide range of sizes and capacity bearing elevators, which, again,...means that at the end of the day, you will not end up with an elevator or elevators that are larger than what your building requires or needs, or than you've actually designed the structure to handle.
As for elevator maintanance costs of fees after construction, that's a known overhead going into it. For the most part.
Every building elevator system (...and we can throw escelators into this as well) requires extensive maintance after the fact and going through the life of the building.
They are mechanical systems that work practically all day and night and are liable to break down quite frequently,....so....
...duh!
I mean, an argument could be made that North American elevator industry is over-regulated which increases costs downward and makes it harder for smaller companies to thrive or even exist or compete with the larger companies - and which likewise also increases the maintainance costs going forward (I think other factors, like unions and labor costs play a role here as well).
