Hi
1. CIC employees processing applications query CPIC, FBI system, US state criminal systems, GCMS, FOSS. System that the employee's working from home would not be able to access.
Let's say it is indeed impossible to process PR cards now. If the CIC was concerned with the health of essential travelers on expired PR cards, and all Canadians for that matter, then they would notify air carriers that expired PR cards are still valid for another year. This would also give them a break as some PRs may receive passports sooner than they need to apply for PR extension. Instead, they have made a choice to make essential travels of expired PR card holders longer and expose them to a greater risk of catching a disease while waiting for the PRTD or going through the US land border unnecessarily.
