So, I participated in this program this past weekend. Lots of lines and waiting in the airport but well worth it.
I arrived into YYC on a WestJet flight from PVR. On board the flight they handed out leaflets about the program and the process. When I arrived in YYC the arrangements for entry were different than my previous return in September, and it took a long time (2 hours from brakes on to walking outside with my bag - but half an hour of that was waiting on paperwork to be processed for importing a dog). First, there was the regular CBSA screening. From what I overheard, the agents were all very positive about the new program and were promoting pax to take part. They asked some basic screening questions that you would have already answered (are you feeling well, do you have a suitable quarantine location, etc), then off to another area crammed into the side of the CBSA hall where the Public Health Agency of Canada had 3 makeshift screening stations setup. I think this part was the bottleneck to the whole process. Here, you were asked either for the confirmation code that you've filled out your contact info on the ArriveCAN app or the paper contact info form (which is going away on November 21 - app use mandatory). Then off to get baggage. After the exit to groundside, there was another station to fill out a basic form to register for the testing program. Then wait in another line to hand the form over to a registrar who entered your info into the computer system and printed out the test forms and sample labels. Finally, the test itself which is your run of the mill PCR Q-tip down the throat.
I received my results 25 hours after the test was taken. As of today, any of the activities that I want to do outside of the home are good to go. Note that there are still restrictions on high-risk scenarios for program participants: can't visit such places as old folks homes, schools, work camps, etc until after the second test or in some cases maybe not even until after the standard 2 weeks. So the program isn't going to work for everyone, particularly if you work in one of these places.
Very happy to have participated in this. It was well worth it and I am thankful for the opportunity to provide meaningful data in support of potentially rolling this out to other airports in the near future.
