Hi!
I'm from Toronto too!!
Most of my friends, who were inland applicants, did their landing at the Peace Bridge.
The others got their COPR and went to home country, visited fam, and then came back and landed at Pearson airport (from what they told me, the "landing" process (interview) itself took around 10 minutes, but the waiting in line took around an hour - you know, airports..)
Also, I know that it's possible to complete the landing in Toronto. You have to call CIC and they will schedule you for a landing interview in one of the CIC offices, whether it's on Dundas, or Etobicoke one. The waiting time for the appointment might take up to 8 weeks though.
