The Halton Hills Chamber of Commerce offers both DIY and Full Service Certificate of Origins. We follow the procedures set out by the Canadian Chamber of Commerce in regards to certifying these documents. Before we can certify your documents, we require either the document to be pre-notarized, or to be provided with a notarized letter of waiver (which is generally easier and less time-consuming for businesses doing an excess amount of shipping). We will keep the letter on file so you do not need to have your documents notarized each time you have a certification done. The letter will be valid for two years, unless your contact information changes.
