The share register or membership ledger of the U.S. entity showing the Québec company as owner, the Québec company's own ownership records, articles of incorporation on both sides, and any holding-company documents in between. Marketing materials with a shared logo do not establish the relationship.
Building the ownership chain
Begin at the top of the structure and work down. If the Québec logistics company is owned by a family holding company, include that company's register too, because the qualifying relationship is judged through the whole chain of control. For the U.S.
entity, provide the certificate of formation, the operating agreement or bylaws, and the ledger entry recording the Québec company's capital contribution, together with the bank record of that contribution arriving. If a U.S. partner will hold a minority stake, document the percentage and any veto rights, since control must be shown, not assumed.
Add the most recent Québec financial statements and a headcount by department to prove the parent is doing business, not merely existing. Assemble these before drafting the petition narrative, because the narrative should describe what the documents show rather than the reverse.
