Court Briefs: A New Way (for lawyers) to Serve Documents (Form 16B.1)
A recent amendment to the Rules of Civil Procedure (Rule 16.09(1.1)) allows for a lawyer to prove service of a document by way of a Lawyer’s Certificate of Service (Form 16B.1) if the lawyer served the document or caused it to be served and is satisfied that service was effected. In cases such as this, Form 16B.1 replaces Form 16B Affidavit of Service and can be used as proof of service when filing documents with the Ontario Superior Court of Justice.
