Seasonal Staff Onboarding Documents: Cross-Checks Before Day One

A Canadian hotel, lodge or restaurant taking on seasonal staff should compare four things before the first shift: the person against government photo ID, the work permit or status document against the offered job and dates, the Social Insurance Number (SIN) against the name on the payroll record, and the account holder on the direct-deposit form against the legal name. These are comparisons between fields on separate documents, and a mismatch on any of them is a reason to pause the start.

This guide is for Canadian employers as of November 1, 2026. It sets out which field is compared with which, what a mismatch looks like and what the reviewer does next, noting where provincial rules differ. It is a consistency method, not a forgery test: documents that agree with each other are not thereby proven authentic. Check the linked government sources before applying them to your situation.

Why seasonal files break at the start of the season

Seasonal hiring compresses paperwork into a few days. A ski resort or lakeside hotel adding forty summer workers usually onboards them in two or three waves while a sous-chef collects documents between services. The usual errors are mundane: a surname in a different order on the work permit and the TD1, a SIN transcribed with two digits swapped, a permit that ends in August for a season that runs to October.

Employers must request a worker's SIN within three days of the start of employment, and a SIN beginning with 9 belongs to a temporary resident and is tied to an expiry date, according to Service Canada. That second fact is the most useful cross-check in a Canadian seasonal file, because it tells you something about the worker's status before you open the permit. The same logic applies to first-assignment checks for agency workers, explained in our article on temp worker file verification before a first assignment.

The cross-check matrix: field against field

The table lists the comparisons that matter for a seasonal start. Each row sets two sources against each other.

Work permit: what it proves and what it does not

A work permit shows that the holder is authorized to work in Canada under stated conditions, and it does not show that the person presenting it is the holder. Compare the photo and name with the person and with the government ID. Many permits are employer-specific, so read the employer's name and the occupation on the permit itself. The conditions are set by Immigration, Refugees and Citizenship Canada, which also describes the rules that apply to employers of foreign workers. Employers hiring under the Temporary Foreign Worker Program have further obligations, so confirm which program applies to each hire.

Canadian citizens, permanent residents and registered Indians do not need a work permit. For them the check is the identity document and the SIN. The practical rule is to decide the route for each person and not for the whole batch.

Permits with an end date

Compare the permit's expiry with the end of the contract. If it expires in August and the season runs to October, the file is in order today and out of order in two months. Put the expiry in a diary or tickler file when you record the permit.

SIN: compare it, do not assume it

A SIN is a payroll and tax identifier and not proof of authorization to work in Canada. It is used for reporting income to the Canada Revenue Agency. The first digit carries information: a SIN starting with 9 is issued to temporary residents and is tied to the end of their permit. Compare the number's expiry date with the contract dates. If the worker cannot produce the number, ask for the confirmation letter from Service Canada rather than accepting a typed number from memory.

Two workers in the same batch giving the same SIN is almost always a data-entry error, but payroll is held until it is resolved.

Privacy: collect what you need and no more

Under the Personal Information Protection and Electronic Documents Act (PIPEDA), organizations covered by the federal law must limit collection to what is necessary and protect it. Several provinces have their own private-sector laws, including British Columbia, Alberta and Quebec. For the Quebec rules, see our French-language article for that province. Retain scans of IDs only as long as the purpose requires, and restrict who can open them.

What seasonal managers ask

Users in hospitality and HR forums tend to ask the same questions. Two come up constantly.

Can someone work a trial shift before the permit is checked?

No. A trial shift that involves serving or kitchen prep is work, even if unpaid, and an employer must not let a person work without authorization. Check the permit first. If the file is not ready, move the start date.

The name on the bank account differs from the ID. What now?

Treat it as a mismatch to explain, not to fix silently. Common causes are a married name, a hyphen, a nickname or a joint account. Ask for a void cheque or bank letter in the worker's name and file it beside the ID. Payroll uses the legal name on the ID, and the explanation sits in the file in case of inspection.

A file standard for a seasonal start

A file is ready for the first shift when each row in the matrix has a recorded outcome:

• Government photo ID compared with the person
• Work permit read for employer, occupation, location and dates, where one is needed
• SIN recorded within three days of the start, with the expiry date if it starts with 9
• Direct-deposit holder matching the legal name, or an explanatory note
• Permit end date compared with the season dates
• A diary date for any follow-up check

Doing the comparison at volume

When fifty files arrive in a week, the effort is in repeating the same comparisons. A document validation tool such as the CheckFile solution for HR teams reads the fields on each document and compares them across the file: name against name, date of birth against date of birth, number format against the expected pattern, expiry date against contract dates. It flags where fields disagree so a person decides, and it does not claim any document is authentic. See how data is handled and pricing before you decide.

Frequently Asked Questions

Which documents should I collect from seasonal staff before the first shift?

Collect government photo ID, a work permit if the person is not a citizen or permanent resident, the SIN, a TD1, direct-deposit details, an address, and any certificates the role needs, such as a food handler or responsible alcohol service certificate required by your province. Then compare them with each other, not only check that each one exists.

Does a SIN starting with 9 mean the worker cannot work?

No. It means the SIN was issued to a temporary resident and is tied to an expiry date. The worker may well be authorized to work, and you check the permit to find out under what conditions.

How soon must I ask for the SIN?

Within three days of the start of employment, according to Service Canada. Ask on day one so that any problem shows up before the first payroll.

Can a seasonal worker on a student permit work in my restaurant?

Possibly, within the limits printed on the permit and the rules that apply to students at that time. Read the conditions on the document and confirm the current limits with IRCC before you schedule hours.

How long should I keep ID scans?

Only as long as the purpose requires, with access limited to people who need them. Set the period with your privacy officer and check your province's rules.
