Zee1234 as far as i know , You will get message in your account.
For me it was different case , I have been living in Toronto since 2012. I was on student visa than on work permit so i was in Canada as worker when i got invitation for express entry and I was also in canada when i got my passport request for permanent residency. So i submitted my passport they stamp immigrant and re send passport back with landing paper with my photo on it. Because when you are in the county you have to submitted everything when you get invitation for PR including photos, After receiving stamping passport and Landing papers back, You have to leave Canada and when you come back you have to submit landing papers to the officer at the airport so in my case there was no photo request.
