No, nothing has been said, the last info was just letter of apllication been transfered to London Ontatio. I saw your case on "April 2021, Got Sponsorship approval (again)", what means again, that's means you as sponsor will be reviewed again and approved again? My sponsorship is actuelly already approved , that means my sonsorship will be reviewed again? and waiting for another approval?Did they say why it was transferred to a local office? Speaking from my experience, (since the same thing happened to me), this means that another officer will be reviewing your application again and they might ask for more information in the future. I will advice you to sit tight, since it might take a while for them to respond again, it did delay my application quite a bit.
If you have more questions, you can call CIC or submit a webform and maybe they can let you know why this happened.
