Thus far it looks like Candians or those traveling to Canada have the biggest issue meeting the test requirements. With the accepted tests being limited to PCR that leaves only two legit tests and only a few labs that do them. None of the labs will guarantee results in less than 3 days and one seems to be fudging the result date accordingly, much to the delight of those using that service. The CDN Govt needs to ease the restrictions on test type and possibly the timeline before the flight or just scrap the whole mess and test upon arrival in Canada. What Canada wants just isn't practical here at this time for most people who need a test. The US requirements seem much more flexible and as a result achievable.
