What @armoured said . . . but with added perspective:Is it really that I am not allowed to travel to Canada anymore , if my PR card is not valid anymore or I go there just for a vacation? That just seems to o harsh in my opinion.
For Context I: In regards to how "harsh" it is to not be able to travel to Canada for a vacation, that describes the majority of people in the world outside North America and Europe, meaning many BILLIONS of people. In regards to what YOU want, OK, that's different, but that is about YOU.
For Context II: In regards to who is "allowed to travel to Canada," as far as Canadian law and rules go, a Canadian PR is allowed to travel to Canada and MUST BE ALLOWED to enter Canada. In regards to the means of travel, again that is a different story, and sure there is a difference depending on an individual's finances, such as whether the PR can afford to fly a private jet or travel abroad a private yacht to travel to Canada. Oh, you can only afford to fly commercial? That's harsh. Maybe not as harsh as it is for the majority of people in the world outside North America and Europe who cannot afford to fly internationally at all. But that's about the person's finances.
To Be Clear I: Canada does NOT have laws or rules prohibiting travel to Canada by a Canadian PR. And, again, Canadian PRs must be allowed to enter Canada.
To Be Clear II: But before allowing passengers to board a conveyance coming to Canada, commercial transportation companies must screen ALL passengers for authorization to enter Canada, which requires presentation of specified documents. This applies equally to ALL passengers, including ALL CANADIANS, meaning both Canadian CITIZENS and Canadian PRs. Canadian citizens, for example, can only be approved to board a commercial flight to Canada if they present a valid Canadian passport or Canadian issued Travel Document specifically for travel to Canada. Similarly for Canadians who are PRs, who can only be approved to board a commercial flight to Canada if they present a valid Canadian PR card or Canadian issued Travel Document specifically for travel to Canada.
Reminder: The extent to which a person with Canadian PR status can travel internationally is NOT controlled by Canadian law or the Canadian government . . . NOR facilitated by the Canadian government. PRs' international travel depends mostly on the passport they carry.
Other than practical and logistical restraints (again, for example, most people in the world cannot afford to fly internationally, even though there may be a billion or two of us who can), a person's access to international travel depends on:
-- the laws and rules of the country that issued the person's travel document, typically a passport
-- -- contrary to some views, the Canadian PR card is NOT a travel document; it is a status document
-- the laws and rules of the destination country
-- exit controls in the country in which the person is located
So the fact that you have Canadian PR status imposes near ZERO restrictions on your ability to travel internationally. In fact, the only impact Canadian PR status has on an individual's capacity to travel internationally is limited to requirements for boarding commercial transportation coming to Canada, which again are very similar to the requirements imposed on Canadian CITIZENS: that is, presentation of a valid PR card or valid Canadian passport, or a Canadian Travel Document for PRs or citizens.
