Read the general eligibility basics overview
Permanent residence in Canada and Canadian citizenship are different legal facts, and U.S. immigration law treats them differently. TN is reserved to citizens of Canada and Mexico, so a PR card cannot support it however many years it has been held. Other routes never asked about Canadian citizenship at all, which is why a permanent resident's options are narrower in one place and unchanged everywhere else.
The route that closes
Hypothetical example: Tomasz is a poultry scientist at a hatchery near Saint-Joachim-de-Shefford, has held Canadian permanent residence for nine years, pays Canadian tax and votes nowhere. An American producer offers him a research role and someone mentions that his profession is on the treaty list. It is, and that does not help, because the list only becomes relevant once the citizenship condition is met. Nationality for this purpose is proved by a passport or a citizenship certificate, not by a PR card, a social insurance number or a driving licence. The disappointment is real and the reasoning is simple: the treaty was made between three countries and extends its professional category to their citizens.
The routes that never depended on it
L-1A and L-1B ask nothing about the employee's nationality. They ask about a qualifying corporate relationship, a continuous qualifying year abroad, and the capacity or knowledge the person will bring, so Tomasz's permanent residence is simply irrelevant to them. EB-5 likewise turns on capital, its lawful source and path, and job creation rather than on which passport the investor carries. E-2 does turn on nationality, but on the nationality of a treaty country, which may or may not be the country Tomasz holds; the Department of State publishes the list, and that list rather than any assumption is what answers the question.
What to do with the papers he does have
A permanent resident preparing any of these should keep the two identities cleanly separated in the file. Show nationality with the passport of the country of citizenship, and show Canadian residence and employment history with the PR card, tax records and payroll. Nothing is gained by blurring them, and an officer who has to work out which document establishes what will ask. Where citizenship is being pursued, note that eligibility opens a route rather than accelerating anything already filed, and that timing it around a U.S. plan is a decision to take with proper advice. Keep the distinction visible in every letter an employer writes as well.
