I was answering #2 in your original post:
1. Do I need a visa to transfer to Canada in ORD/IAD/JFK/EWR ?
I read it as asking if you needed the visa to enter (transfer) to Canada. Like when checking in. Sorry, misinterpreted the question. Perhaps you should have said - do I need a US visa to transit through ORD etc. if staying airside? In any case, was just trying to help.
