How to fill Ontario Form B (parentage) — and autofill it with my-id.ca
Fill Form B for a parentage determination without retyping your details
Form B is a court form used when parentage is in dispute under an interjurisdictional support application — and it repeats your name, address, and details about the child and other party. This guide is an example of storing them once in my-id.ca.
Official form and source
