This almost looks like p1, meaning they think she is inside Canada. It looks like they asked to confirm that she is inside Canada. If this is p1, I think you need to communicate immediately that she isn't inside Canada, as the virtual landing practice cannot be done abroad. I believe they'll resend p1 after she is inside Canada again, but I'm not 100% sure on this. I don't know the full email, so make sure you communicate with them and do exactly what it says.
Edit: If she isn't in Canada and will be returning soon, you could also include the date she'll be back. If she is NOT going to be returning any time soon, they may be able to switch to a physical landing, but again, not sure about that, and you may have to ask IRCC.
