Key facts

  • Address filings to the registry — "St. Thomas OCJ Courthouse (aka. 145 Curtis)" — not to a judge or a specific person.
  • Put your court file (case) number on every page and on the outside of the envelope. Without it, the registry cannot 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 — keep the signed original unless the court specifically requires it.
  • Mailing documents to the court is filing, not serving. You still have to serve the other party separately, by the method the rules require.
  • Watch your deadline. A document is generally filed when the registry receives and date-stamps it, not when you mail it — post well ahead of any limitation or hearing date.
  • Include a short cover letter listing what you are filing and your file number, plus a self-addressed stamped envelope if you want a date-stamped copy returned.
  • PostPal prints your documents and deposits them with Canada Post the next business day for $6 — no printer, envelope, or trip to the post office, with your return address printed for the reply.

Common questions

What is the mailing address for St. Thomas OCJ Courthouse (aka. 145 Curtis)?

Address filings to St. Thomas OCJ Courthouse (aka. 145 Curtis), 30 St.Catharine St, St. Thomas ON N5P 2V8. Put your court file number on every page and on the envelope, and confirm the registry accepts filings by mail before sending anything with a deadline.

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. Filing without serving (or the reverse) 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.
