Hello Mark,
Is the police clearance certificate needed for immigration of the daughter to Canada? If this is what it is for, as in part of your immigration papers, then it would need to be translated into either official Canadian language, and the translation would need to be notarized. Thus eventhough my parents are from Holland, and even if I could read Dutch, you would still need a professional translation and notarization. This usually means lawyers, although there would also be professional translation services as well.
