Your situation

I'm a Lesbian Couple: Starting a Family in Canada

For a lesbian couple in Canada using a fertility clinic and donor sperm, Ontario's All Families Are Equal Act and BC's Family Law Act both let the birth mother's spouse or partner be recognized as the second legal parent automatically, without adoption — using a known donor instead means the same pre-conception agreement rules covered in the Known Donor guide apply, to keep the donor from being presumed a legal parent.

You're a lesbian couple in Canada, and you want to start a family together. Here's how legal parenthood actually works, and where the real decision points are.

What this means for you

Fertility clinic with donor sperm (anonymous or known)

The most common and legally clearest route. In Ontario and BC, once you're conceiving via a clinic with your partner's consent, she's automatically recognized as the second legal parent at birth — no adoption needed. Quebec and other provinces have their own frameworks; confirm the current process where you live.

Known donor (private arrangement)

Using someone you know as a sperm donor, rather than an anonymous clinic donor. This is where the same pre-conception agreement rules from the Known Donor guide matter most — the agreement needs to clearly establish both of you as the intended parents and the donor as not one of them.

Reciprocal IVF

One partner provides the egg, the other carries the pregnancy — both of you have a biological or gestational connection to the child. This is a medical choice on top of the same legal questions above, not a separate legal category.

Key considerations

Which province you're in changes exactly how automatic second-parent recognition is — Ontario and BC are the most straightforward, and Quebec has had its own framework since Bill 12 took effect in March 2024.
The line between 'clinic donor' and 'known donor' matters more for the legal process than most people expect — a known donor, even if you intend for him to have no parental role, needs a proper pre-conception agreement to keep that intention legally clear.
IVF cost matters here too if you're pursuing reciprocal IVF or need fertility treatment beyond simple insemination — Ontario and Quebec's public funding covers one cycle each for eligible residents.
