There might be some matters to take care of if OP didn't permanently move out of Canada (in which case, OP just needs a Canadian accountant). If OP has other Canadian-sourced income, like investments or rental property. Or planning an eventual move to Canada.
But ya, if OP doesn't live in Canada, doesn't have any Canadian assets and doesn't plan on moving to Canada in the near future, the CRA doesn't care.
Or maybe OP lives in Canada and still retains their Mexican status and needs to deal with MX authorities? Canada lets you keep your "Permanent Residence" status without living in Canada for a time (or forever if you stay with a Canadian citizen spouse).
