Filing documents by mail — what matters

Address filings to the registry (the court and location that has your matter) — not to a judge or a specific person.
Put your court file (case) number on every page and on the outside of the envelope, so the registry can match your documents to your file.
Send copies, not your only originals — mail can be delayed or lost, and most filings are made with copies.
Mailing documents to the court files them; it does not serve the other party. Serving is a separate step with its own rules.
A document is filed when the registry receives and date-stamps it, not when you mail it — post well ahead of any deadline.
Include a short cover letter listing what you are filing and your file number, plus a self-addressed stamped envelope if you want a stamped copy back.

Common questions

How do I mail a court filing in Ontario?

Address it to the specific registry that has your matter — the court name on the first line, then the registry's mailing address. Put your court file number on every page and on the envelope, send copies rather than originals, and confirm the registry accepts mailed filings before anything with a deadline. Pick the courthouse below for its exact address.

Is mailing documents to the court the same as serving the other party?

No. Mailing documents to the registry files them with the court. Serving the other party is a separate step with its own rules about who can serve, how, and by when. Doing one without the other can get your material rejected or your matter delayed.

When is a document considered filed — when I mail it or when it arrives?

Generally when the registry physically receives and date-stamps it, not the day you put it in the mail. Build in mailing time and post well ahead of any limitation period or hearing date, and include a self-addressed stamped envelope if you want a stamped copy back as proof.

Should I mail originals or copies?

Copies, in almost all cases. Mail can be delayed or lost, and most filings are made with copies while you keep the signed original. Only send an original when a rule or the registry specifically requires it — and if you must, use trackable mail.
