We are in the same boat just waiting on LPP and oath from scarborough office....Almost the same dates as you, waiting for LPP, Scarborough as well.
It's the worse IRCC office by far, I don't know how they work but they are very inefficient.
I tried to look at different sources and it seems like it takes them between 2 and 5 months to clear LPP, so I'm not expecting anything before february.
It's really a shame that we got assigned to that s**t office
