Hey man, keep your head up. You didn't know any better at the time and now you do because you have been through that. Stay positive, everything will work out for you in the end.
Being removed is not that huge of a deal, specially because you followed all the procedures, you did comply with everything they asked you to do, including the reporting and leaving at the right time and you have no criminal offences whatsoever. That is a good thing on your file. There are a lot of people that return to Canada, even when they are deported and banned.
Like I said, my best suggestion for you is first ask for GCMS notes, you can hire a company to get them for you and it costs usually less than $30. You would be getting them in about 30 days, and they will give you some insight of what's going on in your file. That is the cheaper option.
A step above that, would be having a consultation with a Canadian lawyer (over zoom/facetime), usually they charge about $100 for that, but that money goes towards the process if you do decide you want them to represent you, and ask their opinion and what can be done. Having a representative in your corner is always good because they can direct and advise you better than any of us in the forum can. I can't tell you how much it would cost total, but for a Temporary Visa my lawyer charged me $900, with everything included.
Keel your hopes up, believe it you will get back to Canada.
Fingers crossed for you!
