Yes, in order to have your Power of Attorney Apostilled or authenticated at Global Affairs Canada, it would first need to be sworn before a Canadian Lawyer or Notary Public. This would be done at the time that the document is signed by you or the party. This step is taken in order to ensure that all signatures are authentic and have been witnessed by an official party. Most of our clients use a legal professional they have used in the past for this but if you need help look online for a legal professional who offers the service nearest you.
