What Must Be in an Employment Contract: Federal vs Ontario vs Alberta?

4 min read
The short answer No Canadian jurisdiction requires a single signed employment contract, but each imposes mandatory written disclosures. Federally, employers must give a written employment statement within 30 days. In Ontario, larger employers must give written job information before the first day and issue wage statements each pay period. In Alberta, writing is required for averaging arrangements, wage deductions, and termination notice; Employment Standards Code minimums apply regardless of contract wording.

Comparing federal, Ontario, and Alberta requirements at a glance

None of the three regimes requires a single signed document called an “employment contract.” Instead, each imposes its own mandatory written disclosures, and each sets minimum standards a contract cannot undercut.

Federal (Canada Labour Code)Ontario (Employment Standards Act, 2000)Alberta (Employment Standards Code)
Written contract itself required?No single contract is mandated, but a written “employment statement” with prescribed content is required within 30 days of hire (s. 253.2(1)).No; the ESA sets minimum standards, and an employee “may have greater rights under an employment contract,” but the Act does not require one to exist.No general written-contract requirement was identified; Employment Standards Code minimums apply as a floor regardless of what any contract says.
Mandatory written disclosure to a new hireStatement must include the parties’ names, job title and duties, start date, term, probation length, qualifications, training, hours/overtime calculation, and wage/overtime rate.Employers with 25 or more employees must give written job information before the employee’s first day of work (effective July 1, 2025).Not addressed in the sources reviewed for this article.
Ongoing written pay recordsUpdated statement required within 30 days of any change; employer keeps a copy for 36 months after employment ends and gives the employee extra copies on request.Written wage statement required on or before every pay day, showing the pay period, gross wages and how they were calculated, vacation pay, deductions, and net pay (s. 12(1)).Employer must keep and provide written earnings and payment records.
Written policies triggered by employer sizeNot addressed in the sources reviewed.Employers with 25 or more employees need a written “disconnecting from work” policy and a written electronic-monitoring policy.Not addressed in the sources reviewed.
Clauses that can be void or restrictedNot addressed in the sources reviewed for federally regulated employers.Non-compete clauses signed on or after October 25, 2021 are void, subject to narrow exceptions; wage-deduction authorizations must be specific and written, not oral or “blanket” (s. 13(3)).Deductions for cash shortages or lost property require the employee’s written authorization.
Termination and noticeNot addressed in the sources reviewed for federally regulated employers.A termination clause offering less than the ESA minimum is void; the common law then implies “reasonable notice” instead (Machtinger v HOJ Industries).Both employer and employee must give written notice to end employment; statutory minimum notice runs by length of service. Group terminations of 50 or more at one location within four weeks require at least 4 weeks’ written notice to the Minister.

Which set of rules applies to your workplace

The Canada Labour Code applies to federally regulated employers, and it applies the same way no matter which province the work is performed in. If an employer is not federally regulated, the applicable employment standards law is the one for the province where the employee actually works: the Employment Standards Act, 2000 for work performed in Ontario, or the Employment Standards Code for work performed in Alberta. In all three cases, the statute sets a floor. An employer and employee can agree to terms that give the employee more than the legislated minimum, but a term that gives less is either void outright (as with an Ontario termination clause) or simply unenforceable, with the statutory minimum applying instead.

Where the details diverge in practice

A few items in the table are worth flagging on their own because they show how differently each regime is built.

Federally, the written employment statement is the centrepiece: it must be delivered within 30 days of the start of employment, updated within 30 days of any change to its contents, and retained by the employer for 36 months after the employment relationship ends. The required particulars can be spread across more than one document, such as an offer letter plus a policy manual, rather than a single form.

In Ontario, the writing obligations are scattered across several separate rules rather than one master statement: a wage statement on every pay day, an Employment Standards poster within 30 days of hire, and (for employers with 25 or more employees) a disconnecting-from-work policy and an electronic-monitoring policy delivered to new hires within 30 days. Ontario is also the only one of the three regimes in this comparison with a fact-pack-confirmed rule voiding a specific type of clause outright: non-compete agreements signed on or after October 25, 2021.

In Alberta, the writing requirements tend to attach to specific arrangements rather than to hiring generally: an averaging arrangement (longer daily hours averaged over a set number of weeks) must be in writing and must state the averaging period; a deduction for a cash shortage or lost property needs the employee’s written authorization; and ending the employment relationship requires written notice from whichever side is initiating it, with a separate 4-week written notice to the Minister triggered by larger group terminations.

What this comparison doesn’t cover

This article compares mandatory writing requirements at a high level. It does not walk through the full step-by-step process of drafting a compliant contract in any one jurisdiction, and it does not confirm rules that the underlying sources did not address (for example, restrictive covenants for federally regulated employees, or a general new-hire written-statement rule in Alberta). Readers working through the requirements for a single jurisdiction should look to that jurisdiction’s specific guidance rather than relying on the comparison alone.

Frequently asked questions

Do I legally need a signed written employment contract at all?

Not exactly, in any of the three regimes. Federally, a written 'employment statement' with prescribed content is mandatory within 30 days of hire. In Ontario and Alberta, the employment standards laws set minimum protections that apply whether or not there's a signed contract, though a written contract can still give an employee greater rights than the statutory minimum.

Can a contract give an employee less than the statutory minimums?

No. In Ontario, a termination clause that falls below the Employment Standards Act, 2000 minimum is void, and the common law then implies 'reasonable notice' instead, which is often longer. Alberta's Employment Standards Code and the federal Canada Labour Code likewise set floors that private agreements cannot undercut.

Are non-compete clauses enforceable in an employment contract?

In Ontario, non-compete clauses entered into on or after October 25, 2021 are void under the Employment Standards Act, 2000, subject to narrow exceptions such as certain business-sale situations or very senior executives. The sources reviewed did not confirm an equivalent rule for federally regulated employers or Alberta employers, so that position is not stated here.

How do I know whether federal or provincial rules apply to my business?

The Canada Labour Code applies to federally regulated employers regardless of the province they operate in. If an employer is not federally regulated, the applicable law is the employment standards legislation of the province where the employee actually works, Ontario's Employment Standards Act, 2000 or Alberta's Employment Standards Code.
