I have read multiple posts on a forum that their parents coming in as a visitor (with visitor visa) and they have no problem with it. What they needed were 1) relationship proof; 2) plan of quarantine ( you just prepare one and show it to the customs), and other regular stuff that s needed for getting in Canada (arriveCann app etc). My understanding is that if your parents have visitor visa then they can come in as a visitor first, then see whether they can land in Canada - provided that they can land in Canada.
I just checked the website
https://www.canada.ca/en/immigration-refugees-citizenship/services/coronavirus-covid19/immigration-applicants.html?fbclid=IwAR31GoQuYVeMrRXnQIVECSLdnU95rWTmZ5LYs2C1UjQhuloEd87HUoLt7cc#approved and I think they just updated the website.
If we already approved your permanent resident application
If you’re outside Canada
Note: If your confirmation of permanent residence (CoPR) is expired,
follow these steps.
You won’t be allowed to enter Canada right now if you’re coming to validate your CoPR and become a permanent resident,
unless you are exempt from the
travel restrictions.
You are
exempt from the current travel restrictions and can come to Canada
if you have a valid COPR and:
- the COPR was issued on or before March 18, 2020 OR
- the COPR was issued after March 18th, 2020 and you are an immediate family member sponsored by a Canadian citizen or permanent resident (note that grandparents are not considered immediate family members and cannot come to Canada at this time) OR
- you’re currently living in the U.S. and will be coming to Canada directly (transiting through the U.S. to Canada doesn’t apply)
To meet the travel restriction exemptions, you must also:
- be coming to Canada to settle permanently (you cannot come to Canada and leave to go live in another country, even if it’s temporary)
- show you’re able to quarantine for 14 days
Based on the info above I think they are exempt from the travel restrictions with their valid COPR.
