but compared to UK, Switzerland, Sweden, Norway, Germany, etc....it might be backward...unfortunately my spouse isn't from any of those countries...sigh...
I don't know the details of each country, but whenever I read such comparisons, it turns out that the comparison doesn't hold water. Every country has its specifics - with advantages and disadvantages (depending also on perspective) and I'm not claiming Canada's system is perfect (the processing time being by far the biggest issue).
Two points, one general and one country-specific:
1) One BIG difference is that under Canada's laws, once the spousal applicant (and usually all dependents) has landed and become a PR - that's it, period, that person is a PR utterly independent of the spouse. As long as the PR-spouse (and children) remain in Canada, all rights as any other PR. Path to citizenship straightforward.
When you're making this comparison, can you say that this is true for each of those other countries?
I don't know in all cases, but for many countries, there is nothing like that, or severe restrictions on ability of e.g. divorced spouse to remain in country and retain the same status. (Yes, there is often a mechanism to get permanent status or citizenship - but longer and more complex)
2) UK: I laughed out loud when reading UK in this list. As a few examples: it is quite difficult for UK citizens not currently residing in-country to bring their spouses. Even once the sponsor is back in UK (as far as I'm aware) the monetary/financial requirements are FAR more demanding than in Canada. (A friend is stuck in this situation - can't leave his wife and children, can't afford to maintain two households, can't look for work in UK while abroad (realistically), even if he were able to swing either of these arrangements, he would still need a year or two of employment while separated to get them into UK. (Oh, and the most absurd bit is that pre-Brexit, if he'd been coming to UK with a different EU passport, he wouldn't have faced these tests).
And anyone who follows UK news and Brexit would be aware that there are currently MANY cases of spouses of UK citizens (with EU passports), there legally for long periods of time, employed, with children, that are being refused any status whatsoever due to the Brexit/EU imbroglio. Obviously the whole story not complete, and comparison difficult as no EU-like arrangements in first place to be unwound - but to depict the UK as some easy country in this regard is a bit rich. (Although I'm sure it has some positives compared to Canada's system, too)
It's easy to throw up these comparisons but when they have a different basis entirely - e.g. the permanence of PR status independent of sponsor - it often turns out that these "such-and-such is better" are really just an exercise in cherry picking. (Truly interested to know, if anyone is aware, about the residency status of spouses in EU/Norway/Sweden, for example)
But Canada's processing times are absurdly long for many cases that should be no-brainers. Even before covid. That I agree with.
