See, I live in Ontario. I have two people incoming from the Philippines but have moved recently. I am wondering if I have to tell CIC, as sponsor, where I have moved to. Does anyone know?
If they have received their COPR and visas already, they can update the information for their landing address once they arrive in Canada and clear Immigration.
If the applications are still being processed, submit a Case Specific Enquiry through eCAS. You might not get an answer, but they usually do update changes of address.
