IN THIS GUIDE · The manager who signed the employer letter is leaving before the start date: preserving a verifiable employer contact and duty evidence
Start with the TN eligibility and application overview
Ask for a reissued letter from someone who is staying
The cleanest fix is a fresh letter on company letterhead signed by a person who will still hold authority when the professional starts, typically a successor manager, a department head, or an authorized human resources signatory. The content should describe the same role and the same duties, not a softened summary. Request it while the departing manager is still available to review it for accuracy.
Capture what the departing manager knows before the last day
Hiring managers hold details that never reach a personnel file: why the position was created, what the work involves day to day, who the professional will report to, and how the role fits the team. Ask for that in writing, in factual terms, and route it to the successor so the description survives the handover. An exit interview is too late for this.
Confirm a contact who can actually answer questions
Whoever is named as the employer contact should know the role well enough to describe it consistently and should have a working phone number and address at the company. A departing manager's contact details will stop working. Verify the replacement contact before anything is submitted or presented, and make sure the professional knows whose name to give if asked.
Watch for the changes a departure brings with it
A manager's exit sometimes arrives with a restructure: the reporting line moves, the position is redefined, or the start date shifts. Any of these changes what the letter should say. Ask the employer to confirm the role is unchanged, and if it is not, obtain corrected documentation rather than relying on a letter describing a job that no longer exists.
The failure a departure produces at the counter
A first review of these files rarely stops at the signature. It stops at the telephone extension printed underneath it, which now rings in an empty office, and at a title that no longer appears in the company directory. The single record that settles the question is a reissued letter naming a current officer, that officer’s own direct line, and the same duty list word for word. State the condition plainly: TN admission requires prearranged professional employment with a U.S. employer in a listed USMCA occupation, self-employment is not permitted, and the employer must therefore be reachable as an employer. Hypothetical example: a benefits administration firm hires an Accountant to reconcile plan contribution ledgers; the vice-president who signed resigns in August, and her successor issues a fresh letter in September carrying the identical duty list, her own direct line, and a note that the reporting line is unchanged.
Sequence the reissue before any notice is given
Inverting the order is the common error: the professional accepts, resigns from the Canadian firm, and only then learns that nothing will be reissued until a new manager is confirmed in role. The document that removes the argument is a dated written confirmation from human resources that the requisition is still funded and the title unchanged, obtained before any notice is tendered. The governing condition does not bend for goodwill: the position must sit within a listed occupation and the applicant must hold the qualification that occupation specifies, so a role that quietly becomes a generalist post during a restructure may no longer fit. Ask for the requisition number, the pay grade and the reporting line in one written reply, and keep that reply with the letter rather than in a mailbox.
