No. The evaluation requirement applies to degrees from institutions outside Canada, Mexico and the United States. A Québec baccalaureate is supported by the diploma and transcript alone, plus certified translation if the documents are in French.
Spend on translation and the letter, not on an unnecessary evaluation
The regulation requires a reliable credential evaluation only for degrees earned outside the three USMCA countries, so an agronomy baccalaureate from a Canadian university needs none. Money spent on one buys nothing. What the file does need is certified English translation of the French diploma and transcript under the USCIS translation rule, which is billed by page and should cover only the relevant documents.
Government charges differ between port-of-entry presentation and a Form I-129 petition and change over time; take the port-of-entry fee from the CBP schedule and the petition fees from the USCIS G-1055 schedule on the day of filing. The most valuable expense is usually professional time spent reviewing the employer's written answers and shaping the support letter so that the agronomic work is unmistakable. A refusal at the border for a sales-flavoured letter costs far more than that review, and it appears in every later application.
