Should a foreign company incorporate an Ontario entity or use an Employer of Record (EOR) to hire its first Ontario employee? For most companies hiring one or two people, an EOR is faster and cheaper: no incorporation, no CRA payroll account, no registration with the Workplace Safety and Insurance Board (WSIB). Incorporating (OBCA or CBCA) pays off once you need a local brand, local banking, or more than a handful of employees.
What are the fastest ways to legally employ someone in Ontario?
There are really two paths. First, use an EOR: a third party that is already incorporated and registered in Ontario employs the worker on your behalf under its own CRA business number, WSIB account, and payroll systems, while the worker does the day-to-day work for you. Second, stand up your own Ontario legal presence, either an Ontario Business Corporations Act (OBCA) corporation or a federal Canada Business Corporations Act (CBCA) corporation registered to do business in Ontario, and run payroll directly through your own CRA and WSIB accounts.
Should you incorporate under the OBCA or the federal CBCA?
Both create a valid Canadian corporation that can legally employ someone in Ontario. The government filing fee for Ontario is $300 for provincial incorporation, while federal CBCA incorporation costs $200 CAD online. Setting up a named, non-numbered Ontario corporation requires an Ontario-based NUANS name search report from a private search house, valid for 90 days. Federal incorporation bakes the name search into the online application, so no separate report is needed. Federal corporations must also have at least 25% of directors (or at least one, if there are fewer than four directors) resident in Canada, a requirement Ontario abolished for provincial corporations back in July 2021. For foreign parent companies, this residency difference is often the deciding factor between the two.
The registration path after federal incorporation depends on who is registering. If your existing Canadian corporation, whether federal or from another province, is simply extending into Ontario, you only need to file the Initial Return under the Corporations Information Act, at no fee, within 60 days of starting to do business in Ontario. But if a non-Canadian parent (a US or Korean company, for example) wants to carry on business in Ontario directly, without first setting up a Canadian subsidiary, it needs a full Extra-Provincial Licence. This licence, which applies to corporations incorporated outside Canada, costs $330 online or by mail. In practice, almost every North American or Korean company hiring its first Ontario employee incorporates a new Canadian subsidiary (OBCA or CBCA) rather than registering the foreign parent directly, since the subsidiary route is simpler for banking, contracts, and tax residency.
What does post-incorporation setup actually involve?
Once the corporation exists, three registrations typically follow:
- CRA business number and payroll account: needed before the first pay run so you can remit income tax, CPP, and EI on schedule.
- WSIB registration: most businesses in Ontario that employ workers must register with the WSIB within 10 days of hiring their first full or part-time worker, though coverage isn't mandatory for every business, since the Workplace Safety and Insurance Act specifies which industries require it. Construction is a notable case: coverage is generally mandatory not only for workers but also for owners, independent operators, and executives.
- Employer Health Tax (EHT) registration: the EHT is a tax Ontario levies on employer payroll to fund health care. Registration is required once your Ontario payroll approaches the exemption threshold, and employers that aren't eligible for the exemption must pay EHT starting from their very first payroll dollar; covered below.
How much do CPP, EI, EHT, and WSIB actually cost an Ontario employer in 2026?
Ontario provides EHT relief for small eligible employers through a tax exemption on the first $1 million of annual payroll, but employers whose combined annual Ontario payroll across associated corporations exceeds $500,000 are not eligible to claim the EHT exemption. Rates are graduated: in one official example, an employer with total Ontario remuneration of $1,300,000 uses a 1.95% tax rate because payroll is over $400,000 before the exemption, producing $5,850 EHT owing after the $1,000,000 exemption is deducted, while a smaller employer with $175,000 of Ontario payroll who is not eligible to claim any exemption would use a tax rate of 0.98%, owing $1,715.
On the federal side, the 2026 CPP contribution rate is 5.95%, applied to pensionable earnings between a $3,500 basic exemption and a $74,600 maximum pensionable earnings threshold, producing a maximum employer and employee CPP contribution of $4,230.45 each for 2026. Above that, CPP2 applies at a 4% rate for employers and employees, with a maximum CPP2 contribution of $416, on earnings up to an $85,000 second ceiling, so pensionable earnings between $74,600 and $85,000 are subject to CPP2. For EI, maximum insurable earnings rose to $68,900 for 2026 while the employee rate fell to 1.63%, and employers must match CPP contributions dollar-for-dollar and remit EI employer premiums at 1.4 times the employee rate, producing a combined employer maximum of $6,218.75 per employee once CPP, CPP2, and EI are added together. WSIB sits on top of this, priced per $100 of insurable payroll and set by your industry classification rather than a flat percentage.
| Statutory cost (employer, 2026) | Rate | Earnings band | Max employer cost per employee |
|---|---|---|---|
| CPP | 5.95% | $3,500 to $74,600 (YMPE) | $4,230.45 |
| CPP2 | 4.00% | $74,600 to $85,000 (YAMPE) | $416.00 |
| EI (employer, 1.4x) | 2.282% | Up to $68,900 (MIE) | $1,572.30 |
| EHT | 0.98% to 1.95%, graduated | Ontario payroll above $1M exemption | Varies, no exemption above $500K |
| WSIB | Industry-rated per $100 payroll | Mandatory for Schedule 1/2 industries | Varies by classification |
What is Ontario's minimum wage right now?
As of October 1, 2025, Ontario's general minimum wage is $17.60 per hour, and it is scheduled to increase to $17.95 per hour effective October 1, 2026, two weeks after this article's publish date. An EOR absorbs this update automatically across its payroll; a newly incorporated employer needs to update pay tables itself.
What ESA policies and job posting rules kick in at 25 employees?
Two written-policy duties attach once you cross the 25-employee mark under the Employment Standards Act (ESA). Headcount is measured as of January 1 each year, and if you meet the threshold, the required policies must be in place by March 1 of that year. First, employers must maintain a written electronic monitoring policy describing whether and how electronic monitoring occurs and the purposes for which the information may be used; a copy must be provided to employees within 30 days of the policy being created or updated, and the policy must be updated again every time the employer changes its electronic monitoring systems. Second, employers must maintain a disconnecting from work policy setting out how the employer manages an employee's ability to disconnect from work, meaning not engaging in work-related communications outside working hours, though the requirement does not create a personal right to disconnect for any employee.
Job posting rules changed more sharply. As of January 1, 2026, employers with 25 or more employees must include in public job postings the expected compensation or a compensation range (limited to a $50,000 band, and not applicable to roles paying more than $200,000), disclosure of whether AI is used in the hiring process, and whether the posting relates to an existing vacancy. Employers are also prohibited from listing Canadian experience as a requirement and must inform interviewed applicants within 45 days of the last interview whether a hiring decision has been made. Penalties are real: a conviction for contravening the ESA can result in fines of up to $100,000 for an individual, and for a corporation $100,000 for a first offence, $250,000 for a second offence, and up to $500,000 for a third or subsequent offence. Note that these obligations apply only to an employer with 25 or more employees on the day the job is posted, which matters for the EOR question below: under an EOR, it is typically the EOR's own headcount, not the client's, that determines whether these thresholds apply to postings made in the EOR's name, so contract language should specify who drafts and owns the posting.
Do Ontario's temporary help agency (THA) licensing rules apply to EORs?
This is the caveat most buyers miss. Since July 1, 2024, temporary help agencies (THAs) must be licensed by the Ontario Ministry of Labour in order to operate, and client companies are also prohibited from knowingly using an unlicensed THA. Initial applicants generally must post a $25,000 security to the Director of Employment Standards. Under ESA Part XVIII.1, the client company is jointly and severally liable with the THA for any unpaid wages, overtime pay, and public holiday pay owed to the THA's assignment employees.
An EOR is not automatically a temp help agency, since a genuine EOR is the legal employer of record for an indefinite role, not a staffing placement, but the line can blur if the arrangement looks like short-term staffing rather than payroll and compliance outsourcing. Before signing, confirm in writing whether your EOR operates as a licensed temporary help agency in Ontario or purely as an employer of record, and ask for its Ministry of Labour licence number if the former applies.
When does an EOR arrangement create permanent establishment risk?
Under the dependent agent standard in Canada's tax treaties with Korea and the United States, a foreign company can be treated as having a permanent establishment in Canada if a person habitually exercises authority to conclude contracts in the company's name, even without a fixed office. Canada has not adopted the broader standard the OECD introduced in 2017, under which merely playing the principal role leading to the conclusion of contracts is enough. An EOR relationship is generally lower risk than a standalone dependent agent because the EOR is the legal employer, but risk climbs if the Ontario-based worker negotiates contracts, signs on behalf of the foreign parent, or manages Ontario clients with real authority. If a permanent establishment is found, the business income attributable to it is generally subject to corporate tax at a combined rate of 26.5 percent, made up of the federal net rate of 15 percent and Ontario's general rate of 11.5 percent. Getting a PE determination wrong can turn what looked like a simple payroll question into a full corporate tax filing obligation in Canada, so companies expanding past a single sales-support hire should get a specific PE opinion rather than relying on general guidance.
Checklist: EOR or incorporation before your first Ontario hire
- Confirm whether the role can conclude contracts on your behalf; if yes, get a permanent establishment opinion before hiring.
- If incorporating, decide OBCA versus CBCA based on where you plan to hire next, not just Ontario, and factor in the CBCA's Canadian-resident director requirement.
- Register CRA payroll and WSIB accounts before the first pay run, not after.
- Ask any prospective EOR whether it is a licensed Ontario temporary help agency or a pure employer of record.
- Track headcount toward 25 employees, since electronic monitoring, disconnecting from work, and job posting duties all attach at that threshold.
FAQ
Do I need a Canadian entity to hire one employee in Ontario?
No. An EOR can legally employ the worker on your behalf using its own Ontario registrations, letting you hire in days rather than weeks without incorporating.
Is Ontario or federal incorporation faster for a single Ontario hire?
Both are typically processed within a day or two online. Ontario's provincial fee is $300 versus $200 for federal CBCA incorporation, but if you only plan to operate in Ontario, provincial incorporation avoids the extra Initial Return filing that federal incorporation requires in Ontario. If you don't have Canadian-resident directors available, provincial incorporation is also the simpler route.
When does WSIB registration become mandatory?
Most Ontario businesses that employ workers must register with the WSIB within 10 days of hiring their first full or part-time worker, though coverage depends on your industry classification, and in construction, coverage is generally mandatory even for owners and executives, not just workers.
Who is responsible for ESA electronic monitoring and job posting compliance under an EOR?
Contractually this should be spelled out, but as a rule the EOR's own headcount typically governs its written-policy duties for its own postings, while the client company remains responsible for its own hiring decisions and any postings made directly in its name.
Does using an Ontario EOR trigger permanent establishment for corporate tax purposes?
Not automatically. Risk rises specifically when the Ontario-based worker has authority to negotiate or conclude contracts on the foreign company's behalf, which is why a role-by-role PE review matters more than the EOR-versus-entity choice itself.
