To those who:
are already in Canad (close to Toronto)
want to land soon
do not have a valid US visa and do not like to go to the US border and get a refusal slip (flag-polling)
You can MOST PROBABLY go to Fort Erie, Peace Bridge, make a U-Turn just before the bridge, where the sign says return to Canada, and do the landing process (Most probably means I do not guarantee but I am 96.3% sure that there will be no problem.)
This was what I did on July 9th, 2011. Nobody made any objection. The officer was a bit tough about proof of fund. Although I showed her a letter from my supervisor, she still required other documents. She eventually accepted my bank statement and copy of pay stubs.
