While I can't readily find the same information for Mexico (perhaps because it'd be in Spanish) the answer to these questions is always the same: there's no mechanical formula. You need to convince the officer handling your case you have the means to support yourself on a trip and the ties to return. You send in documents supporting these claims. Canada actually posts "policy, procedures and guidance used by Immigration, Refugees and Citizenship Canada staff" and the relevant page has this:
To assess the adequacy of a visitor's financial resources, you may exercise discretion in the documentation you request from applicants.
Somewhat obviously you can't expect regulation to keep up with all these companies, Transferwise, Revolut, whatnot. So I'd expect them to accept it as long as the story is consistent: you have a contract with the employer and regular income. As for faking such statements, no difference really, it's not like an embassy can just ask a bank whether the submitted statements are valid. Bank secrecy laws are very strict everywhere.
Once again: if your story as presented is solid, you are good to go.
