Clerical error causing headaches with x-border taxes

[Roberto292]

I filed an nr73 back in 2020 and they determined me a non-resident. i didnt file taxes in canada up until my stupid friend who does general accounting services filed for me. I wanted my US taxes done but he did both US and canada. Now that he's filed incorrectly, i have a bill of 60k where my foreign taxes havent been deducted.

I sent in a letter explaining the situation but they told me to fill out an nr73 which i've already done and uploaded. Collections keep calling me and it's been 3 months since i've uploaded my US tax transcript + the nr73. The estimated wait time is 4 more months. Is this normal? Or are they doing further checks? I did travel between canada and US in that year, are they able to see that and can calculate that im not actually a resident?

Any help would be appreciated because the situation is very depressing and it's affecting my work and home life.
