Can Common-Law Partners Be Added to a Partner's Health or Dental Benefits in Ontario?

It depends on your plan. Under Ontario's benefit plan regulation, spouse means a spouse as defined in the relevant benefit plan, so whether a common-law partner can be added depends on the plan's own wording. Health benefit plans are allowed to differentiate because of marital status in order to provide benefits for an employee's spouse or dependent child.

The Employment Standards Act, 2000 generally bars an employer from providing a benefit plan that treats employees, beneficiaries, survivors or dependants differently because of age, sex or marital status, except as prescribed. Ontario's Human Rights Code also treats living with someone in a conjugal relationship outside marriage as part of marital status. In practice the plan's own definition matters most, so read your plan booklet or ask your benefits administrator.

Waiting periods and proof, such as a statutory declaration, shared lease or joint accounts, can vary by insurer, so ask what yours requires before you apply. If you separate or the relationship is unclear, a lawyer can help you understand where you stand.
