Yes. This is how IRCC maintains these 12 months of processing time:FWIW I have two colleagues who got their invites in the last two weeks, both for oath in September. They both applied in early 2020, about 7 months after I did… they both passed their tests in late June and early July.
One person has 18 months from submission to DM. Another - 6 months. This gives an average of 12 months...
Do not forget that your application is considered fully processed now. The time when you wait for the oath does not count, even if it's one year or longer:
"Your processing time starts the day we receive your complete application and ends when we make a decision on it."
