Usually registrar fees for certified copies, translation of the original documents, courier costs, and legal time to review the discrepancy. A second full evaluation is an added expense that may not be needed if the difference turns out to be a matter of wording.
Confirm what is genuinely required before ordering it
Identify whether the existing evaluation satisfies the actual TN requirement before ordering a replacement. Degrees from institutions outside Canada, Mexico and the United States require a reliable foreign-credential evaluation under the TN regulation. A wording discrepancy may call for a correction rather than a second complete report. Quote that scope separately from translation and institutional records.
Translation and evaluation are different services even when one provider offers both. Licensing and hospital credentialing usually involve their own applications, verifications of training, and document requests from institutions that may be in another country. Field assignments often involve employer-paid travel, camp costs and equipment, and those arrangements are usually clear. Costs in a TN matter divide more cleanly than people expect, and the dividing line is ownership of the document. Review the actual proposed work and applicable licensing requirements without purchasing unnecessary services or treating a licensing payment as work authorization.
