Is there a maximum amount of time someone can stay in Canada on a specialized knowledge intra-company transfer?

Yes, generally, the specialized knowledge category of intra-company transfer has a defined maximum stay built into its structure, and it is not intended to allow someone to remain in Canada on that status indefinitely. The specialized knowledge and executive/managerial categories are each structured with their own maximum-stay framework, and the limits attached to each category are different from one another.

What often confuses people is assuming that as long as the underlying job and the Canadian office continue to exist, the work permit can simply keep being renewed without limit. That is not how this category works — each renewal is a fresh eligibility assessment, and even if the role and business are thriving, the transferee is still working within the category's own maximum-stay structure rather than an open-ended arrangement. Growth of the Canadian office, more responsibilities, or a longer track record with the company does not by itself extend that limit. People approaching the point where this becomes relevant sometimes need to consider other options, such as a different work permit category or a permanent residence pathway, well before reaching it. Because the exact structure and how it applies to a specific case can be technical, anyone in this category should confirm their specific timeline and options with an immigration lawyer.
