No shots...not getting in.

Don't spin your wheels too much on false documentation. The number of people who want to cross to Canada, and willing to falsify documents is small. Then subtract out the number that have antibodies from a very mild bout of Covid, and it shrinks to almost nothing.

Remember:"Quis custodiet ipsos custodes, a Latin phrase from the Roman treatise Satires of Juvenal, written around AD 100", you know "Who watches the watchers". A corrupt government official (how many of those around?) is all you need to enter your info into the database.

My last experience with this was over 10 years ago, a nice lady was selling CDLs with full backup (test scores, driving history, testing sign off, the whole thing) near Baltimore for $300. Even though we and other employers reported something "funny" to the state, it still took a couple of years for her to be arrested.

There is not much you can do with the leakers, but really how many will there be?

So why not allow those of us, willing to provide documentation, entry?

And if your current system is so good, how do the new variants make their way in? Just asking!!
