I would like to thanks to:
and Red Panda
For giving me great tips and directions for spotting at YYZ.
I spent there 11 hrs spotting taking 16 rolls of pictures, first beside runway 5 (Skyservice Charters - I guess), then wind had changed and they were landing on runway 23, so we went to Boeing parking lot.
Weather was not so great but sometimes sun showed up for quite a bit of time.
I had great time in Toronto, I've met few local spotters which were very friendly. I even borrowed ladder from one of them to get pics of Mexicana A320 with 80 years sticker and Roots Air B727-200
Thanks all for helping me out.
