But this raises other practical questions: Now that there is no legal requirement to be resident in Canada during the processing period . . .
I have not engaged much in more recent discussions about whether a PR can apply for citizenship from abroad (even though residency/presence related issues tend to be among my more focused interests). Sure, there are undoubtedly some PRs now abroad, or headed abroad, who did not qualify for citizenship before going abroad but who will qualify when the 3/5 rule takes effect. So, in a sense it is a realistic hypothetical.
But what the law technically, hypothetically allows, can be very different from what is practically feasible. I realize I tend to be a bit overbearing about some things, including pounding on the recognition that technicalities are one thing, practicalities are another. But a lot of posts and points of view expressed in this forum put way too much weight on technicalities, sometimes hyper-technicalities, underestimating the importance and impact of the more practical elements and considerations.
Some examples are more salient than others, but among the more common in the settlement-in-Canada part of this forum, there is the steady stream of PRs who have not settled permanently in Canada, who return to Canada for a time to apply for and obtain a renewed PR card, who are
cutting-it-close relative to compliance with the PR Residency Obligation, and they end up here, in the forum, whining
whaaaa happened? when IRCC bogs down their PRC application in Secondary Review. Some go so far as to assert that they had
"way over the 730 day requirement" because they declared 800 or more days in Canada, despite the fact that even 900 days in Canada amounts to being outside Canada more than in Canada. That signals someone who has not settled permanently in Canada. The purpose of granting someone PR status is so they can settle permanently in Canada. No advanced engineering degree necessary to figure out the blueprint for this scenario.
Getting back to the prospect of a "qualified" PR applying for citizenship while living abroad: the practical hurdles are high and rife with pitfalls without even considering the impression made. Succumbing to temptation to fudge some details (really meaning to make misrepresentations), to minimize or divert negative impressions, will sabotage more than a few. I am not inclined to illuminate ways to make doing this easier, with greater likelihood of success, even though for some the time abroad arises from compelling circumstances and otherwise they are persons sincerely striving to become Canadian citizens consistent with what it really means to be a citizen.
And then getting back to the prospect of qualifying for and obtaining Canadian citizenship without really being a resident of Canada. Technically possible. Sure. The hurdles are higher than high. The pitfalls are many. The logistics are daunting. A person would really have to go way, way out of his way to make this work.
And Canada can probably afford to allow some people to become citizens either of these ways. It is one thing to allow a few rather uncommon persons, outside the planned/desired stream one might say, to obtain Canadian citizenship, versus flaws in the system which could facilitate widespread opportunism and abuse, or even outright fraud.
Moreover, some of the statements made during the final debates about Bill C-6 indicate that Trudeau's government may be overtly embracing those who might be called globalists, overtly encouraging immigrants whose ambitions are tied to global mobility. The opposite of the Harper government agenda, which tended to see those
applying-on-the-way-to-the-airport, or who otherwise had plans which were not firmly rooted in geographical Canada, as a problem to be contained if not eliminated.
Nonetheless, the mere possibility that some might be able to manipulate the margins probably doesn't deserve a lot of concern. I do not see this as a four-line highway wide open for opportunists or those otherwise with an agenda to exploit the Canadian immigration system. And in the meantime, there is much which remains to be seen.
