Nope, I suggest declining the ITA and re applying. You might come across as "lying" about your status in Canada if you don't but it would be a good idea to wait to see what others have to say.
I'm not surprised, they're getting way too many phone calls. My friends friend works with IRCC and he said that everyone's fed up with the number of phone calls.
Does anyone know if they stop processing your application till you get your biometrics done or do they continue to check your eligibility etc till you send in your biometrics ?
I don't understand your comment.
You passed the medical exam and submitted your biometrics but you're still waiting to hear back from IRCC after the same ?
