Filing for Separation in Ontario: A Step-by-Step Guide
Everything you need to know about the legal process of separation in Ontario, from initial steps to finalizing your separation agreement.
Quick Answer
There is no formal "filing" for separation in Ontario. You become legally separated the moment you and your spouse decide to live separate and apart with the intention to end the marriage — no court application required.
However, you should document the separation date, negotiate a separation agreement covering property, support, and parenting, and consider filing for divorce after 12 months of separation if you want to legally end the marriage.
