Online application only started on November 30, 2020. I don't think anyone who applied online received test invites. I saw December 2019 applicants receiving test invites today, so hopefully testing is ramping upThe ones who are getting test and oath invites probably applied through online application. Seems like IRCC is processing Online applications than paper applications. For paper applications they have to go to the office for Online they can work from home so the paper applicants are stuck in a limbo. Expect a wait for an year or two.
Now is the time to file a petition in Supreme court of Canada. All applicants must come together and file a petition against IRCC for delaying.
