While I am not sure that any further clarification is needed . . .
The short answer, as
@armoured said, is that "
A PR does not need the [essential travel]
exemption to the . . . " [Covid-19 related]
ban . . . " because a PR is NOT subject to such a ban.
But to be clear, just like Canadian citizens, PRs have NOT been banned or otherwise prohibited from traveling to or entering Canada whether their travel is discretionary, non-essential, or essential. While certain conditions have been imposed (like quarantine), regarding which the purpose of the travel can have an impact on PRs, for this there is essentially little if any difference between travelers who are Canadian citizens versus Canadian PRs.
Thus, in particular, a Canadian PR (just like a Canadian citizen) does not need to establish the purpose for travel is essential in order to travel to Canada. A Canadian PR can board a flight coming to Canada even if the PR's travel is discretionary or otherwise non-essential.
However, a Canadian PR must nonetheless meet the requirements for presenting certain documentation (namely a valid PR card or PR TD) in order to get permission to board a commercial flight to Canada.
Beyond that, what appears to need emphasizing is that to the extent there remains some confusion it probably derives from failing to clearly distinguish --
-- immigration laws and rules governing who is authorized to ENTER Canada, versus
-- the rules governing who can board commercial transportation headed to Canada, regarding which
-- -- there are the general rules requiring presentation of documentation from a specific list, and
-- -- additional, SEPARATE temporary restrictions imposed pursuant to Covid-19 (global pandemic) measures
Even though the general rules governing the boarding of flights to Canada are in part based on immigration laws and rules (including laws governing who is authorized to enter Canada), and part of the system for enforcing immigration law and rules, the differences are important. Moreover, confusion derived from the impact of the differences is currently aggravated by the particular travel restrictions imposed due to the global pandemic.
I do not mean to presume what you meant,
@kathysrazor, but it appears your personal experience was not about being denied boarding a flight to Canada because you are a PR but because you could not present the documentation necessary (PR card or PR Travel Document) for a PR to board a commercial flight to Canada . . . after all, you were allowed to travel to Canada (and then enter), just not aboard commercial transportation.
And otherwise, a traveler carrying a U.S. passport is subject to the Covid-19 restrictions.
Beyond that, what happens in a particular situation can also vary from what should happen according to the applicable rules, so it is always risky to draw conclusions about what the rules are based on what happened in one instance.
For further clarification, the exemption which allows a Canadian PR (also applicable to a Canadian citizen) who is a U.S. citizen to fly to Canada without a PR card (Canadian passport for Canadian citizens), or PR TD, is NOT about a rule for PRs in particular. This is part of the overall U.S./Canada relationship pursuant to which certain documentation showing citizenship in the other country is sufficient for purposes of being allowed to board a flight to the other country. U.S. citizens can board a flight to Canada regardless of status in Canada.
However, this [exemption] is currently subject to the additional, separate restrictions on travel imposed pursuant to Covid-19 measures. So, for example, for individuals seeking to travel to Canada based on their status as a U.S. citizen, for the last year the purpose of the travel (essential or non-essential) matters.
Another clarification worth highlighting is that the rules governing travelers boarding flights to Canada generally are specific as to necessary documents . . . for purposes of boarding a flight, it does NO good to prove a person is a Canadian PR, or for that matter a Canadian citizen, since only certain documents qualify to meet the rules governing who airlines may allow to board the flight. That is, it is NOT about whether or not the individual traveler is actually, in fact, a PR or not, but about whether the traveler presents documentation on the list of acceptable documents for boarding flights to Canada. Likewise for Canadian citizenship. Proof of citizenship is not sufficient. A born in Canada birth certificate supported by a dozen affidavits including one from a deity will NOT suffice. The traveler needs to present either a Canadian passport or a special travel document.
Which loops back around to the rule allowing a U.S. citizen to board a flight to Canada, even if the individual is a Canadian PR or Canadian citizen without the documentation generally required of PRs or Canadian citizens. But again, this means this traveler (U.S. citizen without a PR card or PR TD) is subject to any Covid-19 restrictions applicable to U.S. citizens (and thus for the last year the travel must be meet the essential travel guidelines) even if the traveler is a Canadian PR. Which has NO effect on the traveler being allowed to travel to Canada using private transportation.
quotes for reference:
Right now, discretionary travel by non-Canadians (including PR) to Canada is essentially banned.
To clarify, I wasn't suggesting PRs are banned. Specifically, if one does not present as a PR, then as far as the airline is concerned, you can be banned (for example, non-essential travel). Even if you have an "exemption to the ban" (essential travel), it's not available as that exemption is for non-Canadians.
PRs are Canadians, and were never subject to any bans in the first place, therefore a PR can't use the exemptions available to non-PRs.
To be clear, the earlier reference to "
non-Canadians (including PR)" makes no sense. As your last observation said, and it is correct, "
PRs are Canadians." There is no non-Canadian PR. In particular, those who have PR status in Canada are defined, by law, to not be Foreign Nationals. (Section 2(1) IRPA, which can be seen here:
