Quite what language the IRCC thought I was speaking at the time is beyond me.
There's a point in bureaucratic processes where there is no thought at all, but a task to tick the box / proceed only when something fits the exact language, eg. 'certifies' that [something like 'language of instruction'] English. And of course - jurisdictions that teach only/primarily in English don't certify such a thing [because bleeding obvious and cannot think of anyone who would ask such a daft question.]
It's rather like in another thread, there are a handful of US states that don't issue marriage certificates (the license is completed and registered and stamped or something, that's what certifies a marriage, or if you prefer, a 'completed' marriage license is a certificate). This periodically baffles IRCC (probably doesn't help that these documents are issued by counties not states/provinces).
Of course there's someone senior who understands or has common sense, but the people doing document checks don't like going to them, and it's ... let's say 'expensive' (in time or whatever) from the outside to invoke that deity.
Probably someone somewhere periodically writes instructions to explain these odd exceptions but of course ... you have to have epxerience or initiative to know where to find this info and look it up, which the junior staff doing these things doesn't have (if they knew all that, they'd be senior, innit? - as they say).
Now leaving aside that those US states should get a proper centralized registrar - Canada has its own issues of federalism, like there is no Canadian authority that can say whether or not a Canadian is / has been officially married/remains married acc to local law etc. There are at least 13 of them, and they don't really cooperate on this. (This astounds some foreign officials, and not surprisingly). Heck there's no common understanding of common law relationships.
The analogy I've used for years: all bureaucracies have a number of gears and mechanisms turning furiously, some fast, some slow. And different bureaucracies always have different-sized teeth on their gears; when those gears are forced to work together, they grind more than they ought. Sometimes not very much, but sometimes a lot.
(The IT analogy would use different terminology, of course)
But alas, I know they are extremely busy and sometimes it leads to these type of scenarios. I have no hard feelings.
This is the only correct way.
