Just because the instructions do not state do not get MFA approved. Does not mean you should not get it.
Actually it pretty much does mean that.
Does it hurt to spend a couple extra hours to get it MFA approved? I geuss not. If you do not want to, thats fine, but I am talking from Experience.
Even if I list you the countries, does not matter.
I don't know if I'm talking from capital-letter Experience, but this is not my only time around the block.
Does it 'hurt' to do pointless extra steps? Well, for some, getting this done at MFA is not painless - it can be lengthy, costly, and involve extra travel.
More importantly, if doing pointless extra steps means spending time on things that are not needed, a risk - possibly significant - that applicants will concentrate on the wrong things and miss what is important.
For background for those that actually pay attention: in many countries, the process of getting documents authenticated (sometimes called apostille'd) by foreign ministry/similar designated agency is common because they are signatories to the Hague Convention - notably for example USA is a signatory. Canada is NOT a signatory and uses its own approach country-by-country (why Canada does not participate is a separate issue but short form, federalism and the constitution - these docs are often provincial responsibility).
(The annoying thing for Canadians is some other countries will require this, and so Global Affairs kind-of sort-of provides the service where absolutely necessary, but it's costly and slow and hard to do from abroad.)
So b/c Canada is not in the Hague Convention, there's no presumption that Hague-type authentications are necessary or sufficient. IRCC
may require it from some countries but it's far from 'standard.'
But sure, if it makes anyone feel better to do it when not necessary, go ahead.
