Possibly, but the answer depends on the profession’s requirement and what reliable evidence can establish that it is met. Missing proof and a missing qualification are different problems. Canadian or Mexican citizenship and an employer’s support do not remove the credential requirement.
Ask an evidence-specific question
Explain exactly which record is unavailable, whether the qualification was actually earned, and what other records exist. A reviewer may need a transcript, institutional verification, evaluation, or other material appropriate to the issue. Do not assume work experience replaces a degree where the profession requires that degree.
If the evidence cannot establish the required fact, the useful decision may be to wait or reconsider the immigration route. Credential disputes are settled by the record the awarding institution issued, rarely by a summary of it. Establish what the reviewer must be able to see: the conferral, the field of study, and where a profession requires it, the licence or professional membership.
Experience letters carry weight only where the profession itself recognises experience, and they should state dates, duties and the writer’s basis of knowledge to be worth reading. Hypothetical example: An agronomist offered a post as an Agriculturist finds the diploma names a broad science programme, so the transcript listing the agronomy coursework becomes the document that answers what the diploma left open. Citizenship of Canada or Mexico is a separate fact again, shown by a passport or citizenship certificate and not by long residence.
