- EI premiums are only deducted from — and EI benefits are only available for — employment that qualifies as "insurable employment" under the Employment Insurance Act.
- The key question is not your job title or how much work you do — it is control.
- Most small Ontario corporations are set up with one person, or one couple, holding all or most of the voting shares.
Business owners who incorporate and then draw a salary from their own corporation often assume they are an employee like any other — T4 issued, source deductions withheld, Employment Insurance (EI) premiums included. For a genuine minority shareholder working alongside unrelated owners, that is usually correct. But for someone who controls their corporation, EI often does not apply at all.
This comes as a surprise to many owner-managers, especially when a payroll provider sets up deductions as though EI applies by default. Understanding the controlling shareholder EI exemption matters for two reasons: it affects your take-home pay and remittances now, and it determines whether you would even be eligible for EI benefits later if your business fails or you stop working.
What "Insurable Employment" Means
EI premiums are only deducted from — and EI benefits are only available for — employment that qualifies as "insurable employment" under the Employment Insurance Act. Most regular employer-employee relationships qualify automatically. But the Act carves out certain relationships that do not qualify, no matter how the parties label them or how payroll is administered.
One of those carve-outs applies to employment between people who do not deal with each other at arm's length — a category that, for EI purposes, includes a corporation and a shareholder who controls it.
The Non-Arm's-Length (Control) Test
The key question is not your job title or how much work you do — it is control. If you, alone or together with a related person such as a spouse, control enough of the corporation's voting shares to control the corporation itself, your employment with that corporation is generally treated as non-arm's length, and therefore not insurable for EI purposes.
This is a factual and legal test that looks at actual voting control, not perceived involvement in day-to-day operations. A shareholder who owns a controlling block of voting shares can be excluded even if they are not the most active person in the business day to day. Conversely, an active, hands-on manager who owns only a minority stake alongside unrelated co-owners is usually still in insurable employment.
Why This Usually Applies to Owner-Managers
Most small Ontario corporations are set up with one person, or one couple, holding all or most of the voting shares. That structure — common precisely because it is simple — is exactly the fact pattern the non-arm's-length exclusion is built around. The practical result: a large share of incorporated small-business owners in Ontario who pay themselves a T4 salary are not actually paying into, or eligible for, EI through that employment, whether or not their payroll software says otherwise.
Minority vs. Controlling Shareholders — a Quick Comparison
| Minority shareholder (no control) | Controlling shareholder | |
|---|---|---|
| Typically insurable for EI? | Usually yes | Usually no |
| EI premiums deducted? | Usually yes | Should not be, once status is confirmed |
| Eligible for EI benefits from that job? | Usually yes, subject to normal eligibility rules | Usually not, from that employment |
| Who decides? | Facts of the working relationship | Voting share control, alone or with related persons |
What to Do If You're Not Sure
If it is unclear whether your role is insurable — for example, share ownership is split among several family members, or voting control is structured in an unusual way — you or your employer, including your own corporation, can request a formal ruling from the CRA on whether the employment is insurable. Relying on an incorrect assumption in either direction has a real cost: over-deducting EI needlessly reduces take-home pay, while under-deducting when EI actually does apply can lead to a reassessment for unremitted premiums.
Frequently asked questions
If I don't pay EI premiums as a controlling shareholder, can I still get EI benefits if my business closes?
Generally no — if your employment with the corporation was excluded as non-arm's length, you will not have built up insurable hours toward EI benefits through that job, even though the business itself may have failed.
Does this exemption apply to CPP too?
No. This exclusion is specific to EI under the Employment Insurance Act. Canada Pension Plan contributions generally still apply to salary paid to a controlling shareholder in the same way as any other employment income.
What if my spouse and I each own shares and neither of us controls the company alone?
Control can be assessed on a combined basis for related persons in some circumstances, so joint ownership between spouses does not automatically avoid the exclusion. A CRA ruling request is the reliable way to confirm status in a shared-ownership structure.
Can a controlling shareholder ever be in insurable employment?
It is uncommon but not impossible — the analysis depends on the specific facts of control and the relationship, and unusual share structures can change the outcome. This is exactly the kind of situation where requesting a ruling is worthwhile rather than assuming either way.
