Well, really depends on when you move, I guess. If you move early on (for example, before your application moves to "In Process" status on ECAS) and immediately update the address, then Sydney will send your file directly to the responsible office in the GTA for processing. If you move after Sydney sends your file to the Quebec office and then change your address, then that might result in a file transfer and might result in some delay.I sent documents for my family yesterday to Syndey, Nova Scotia. I currently live in Quebec but may relocate to Toronto later this year or early next year. Does anyone know how this affects application processing ..
Here's more information on change of address:
