Sorry to hear that. I think that was the expected outcome unfortunately based on other experiences on the forum and communications from CBSA/IRCC regarding the processing of work permit applications at the border.WELP I tried! I got past CBSA officer no problem - he was very supportive. IRCC officer was a massive dick...basically, he told me he has the power to determine whether I'm essential or not, and what he considers essential is a doctor or a nurse, period. This is when I started ugly crying (can't help my emotions haha).
He suggested calling IRCC (which, lol, I can only do if inside Canada). Glimmer of hope: they're easing up the auto trade restrictions shortly, so this might be an indication for other less-essential travel to start going back and forth again. Also, he told me even if I have a POE letter, it's unlikely the border will let you through unless you have support from your employer that your job is still current and essential...and that definition of essential is entirely up to the officer you're lucky enough to get on that particular day.
My advice: don't try it (unless you're like 30 minutes from the border like me, then go for it bc there's really nothing to lose) until the border restrictions ease (~May 20 earliest for the USA), or the Quarantine Act is lifted (June 30 earliest).
I'm back home now having hot chocolate and snuggling with my dog.
You still have the online application processing, right?
