Amber,
I took all my documents to the multicultural center in my city (Kitchener).
If you go online to
Settlement.Org - Providing information and answers to settle in Ontario, Canada. it will tell you if you have a multicultural or settlement center in your city.
I found them to be cheaper than most places.
It was $30 for the marriage certificate and $25 for all other documents.
They included a cover page from the certified translator, a photocopy of the original document and the translated information.
All three were stamped and signed by the translator and a commissioner of oath to certify the documents.
Good Luck
