Advice on work permit option

Here’s my landing experience 7/12…took taxi from Detroit airport to Windsor. Officer asked questions about why I’m here, what documentation do I have, vaccination status and goods to follow list at the Tunnel toll plaza. took ~15min then handed over yellow slip along with documentation to go to the Customs area. Surprisingly, Didn’t give BSF goods to follow form to fill. Officer at the Customs asked same questions and took documents went inside and came back after ~30min with work permit copy. There were no one except us at that time.

Weird thing is that Drivetest didn’t allow to exchange DL when went next day said to come after 14days even after saying exempted from quarantine said they make their own rules doesn’t necessarily follow federal rules.
