Hello! You might be Canadian.
I'm sharing this specifically for my American trans siblings, because many people are positively impacted by this. If you're looking for options for your safety, this might be a way.
Canada did something wild at the end of last year and removed their generational limits on Citizenship by Decent via Bill C-3. That means if you have a direct ancestor (parent, grandparent, great grandparent, xgreat grandparent) who was naturalized in Canada or born a Canadian Citizen, everyone in that direct chain of decent is also Canadian, regardless of where they were born. There seems to be no generational limit as of right now--if you can prove that your ancestor was Canadian through various documents such as birth and marriage certificates, name change court orders, census and baptismal records, etc. then you can get a certificate of citizenship which allows you to apply for a Canadian passport, apply for jobs, benefits. You are a citizen. This is not an immigration process, it is simply a civil change to correct various sexist and xenophobic laws that have impacted generations of Canadians who moved abroad and had children.
There are special rules for people who were adopted, but you may also qualify.
Even if you think there's no way, an ancestor who immigrated from Europe by boat to Canada, stayed long enough to have a kid, and then migrated to the US would be Canadian by way of naturalization.
There are some issues I have here--namely the preference this gives to White settler-colonialists while Xenophobia runs rampant in their Immigration processes; Canada's genocide of First Nation, Inuit and Métis peoples which as been ongoing since it was first invaded by Europeans, and the fake line drawn between Canada and the US is part of that genocide. White settler's ancestors were part of that genocide. Who is documented and who is not is evidence of that genocide. Bearing that in mind, I think it's also vitally important to have options right now, and if you are white or benefit from White Supremacy, and it turns out you're Canadian, and DO move to Canada, there is more work to be done regarding reparations and what it means to be a dual citizen on this continent when so many are denied rights.
So... How do you find out? Genealogy research!
Ask your family if you speak with them, get names, dates, locations of birth and death etc. of ancestors.
Visit Family Search and look up your grandparents, and their parents etc. on both sides of your family. Where were they born?
Reddit thread on searching for records
Your local library will often have genealogy resources like Anestry.com for free
Do not do a DNA test, this will tell you nothing and will sell your genetic data to private companies

If you find out this applies to you, start reading up on the application process. There's a lot of information but also so many people are going through this process that can help
This is the page linking to the application on the Canadian Government website: https://www.canada.ca/en/immigration-refugees-citizenship/services/canadian-citizenship/proof-citizenship/apply.html#apply-paper
There are also simple and non-arduous options to have your name and gender marker appear correctly on any Canadian documentation even if they are incorrect in the US due to transphobic laws.
If you have questions, please let me know and I can do my best to help. This is a big deal and quite confusing at first because in practice it's very simple. We just live in a world where we expect there to be rules and restrictions on everything, but if you have a direct Canadian ancestor, you're already Canadian. You just need to prove it.
