I've read through your past posts and for the most part, it appears you are looking for a NO RISK at all procedure*.

I'm looking for no erosion resorption and no infection risk that sits well on the skin and maintains its structure.
Not only that but, 'ideally', you would like your Canadian doctor/s to perform SPECIALTY procedures that only a small handful of doctors (not in Canada) are conversant/skilled at doing whether they be paranasal implants** or innovative paranasal displacment surgery by Alfaro.

Where to get paranasal implants done in canada?
Let's get REAL. For all intents and purposes, these procedures can be considered ESOTERIC procedures LIMITED to doctors of KNOWN capacity to perform them
a: Your Canadian doctor/s is/are not going to be as conversant as is a doctor KNOWN for putting in paranasal implants. (Name of doctor is listed in the bibliography of the article you cited.)
b: Your Canadian doctor/s is not going to be as conversant in performing Alfaro's isolated paranasal displacement surgery as is the innovator of it.
c: What ever the inherent risks are with paranasal implants or Alfaro's isolated U shaped osteo of the paranasal area, they would tend to be even HIGHER in the hands of doctors who are not PIONEERS or 'movers and shakers' in the particular venue you are seeking.
If I wanted paranasal implants, I would go straight to the doctor listed in the bibliography who is expert in putting them in (Yaremchuck). Alternatively, if I wanted a BONE CUT instead, I would go straight to Alfaro. Although seeking out those 2 experts for EITHER don't make the inherent risks of the surgery go away, you shouldn't even be thinking about having your Canadian doctor perform EITHER. I mean it's intuitively obvious to me that the risks would be HIGHER in the hands of doctors who are not the 'movers and shakers' or 'innovators' of these types of surgeries.
Moral of story: STOP THINKING about any possibility of your Canadian doctor performing this. How on earth someone wanting the LOWEST risk possible for an ESOTERIC surgery would have ANY expectation that their local doctor could carry this out with expectation of a LOWER risk than the experts have, I will never know. Can't fathom the reasoning because to ME, it's irrational expectation/ PIPE DREAM.
Doesn't matter if you did not specifically say you 'expected' your doctor to be able to carry this out with lower risk than the experts in this. Your posts belie you harbor some kind of subconscious expectation that your Canadian docs will be in same capacity of the 'grand wazoos' of the type of esoteric surgeries you are wanting. I also pick up the 'vibe' of that type of thinking when you say your 'only option' (here the phrase is used in the PEJORATIVE sense) is to go to .. (eg. the EXPERTS in this as IF they are the LESSER option). It's a 'Can't have the horse take the donkey.' type of thinking. BUT where your priorities are MIXED UP where the Canadian doctor is the 'horse' and the EXPERT(s) in this is the 'donkey' It's the other way around. The expert(s) in this is/are the HORSE(s) and your Canadian doctor(s) is are the DONKEY/donkeys.
That said, if you want to know MORE about this 'U' type osteo, PRIORITIZE your consult with Alfaro. He's going to know more about whether or not you are a good candidate for it and what the risks are IN HIS HANDS.
Oh, did I forget to mention that the answer is
'NO' regarding your Canadian doc doing this for you?
