Good news everyone! I became a permanent resident yesterday.
The landing process at Toronto-Pearson was smooth and surprisingly fast. Went from kiosk to primary immigration officer to secondary (for PR activation) ... all done in 5 minutes total. Since I don't have a permanent address, they didn't take my address and told me fill out the PR card form later.
Then I told the customs checkpoint that I have goods to declare and they sent me to customs screening where they stamped the BSF186/A forms and gave me the blue slip. Again, all done within 5 minutes. I guess it's only the departures which are horrible at Pearson.
