Hi, I didn't read all of the thread to see if you got a satisfactory answer but depending on which province you live in, you would be protected by the Canadian Charter of rights. From what I learned from a LeLeche League meeting, you can breast feed anywhere in Ontario and BC, however if you were in an establishment that children are not allowed to be present in (IE: a bar) then the owner can ask you to leave, however a court room is well within your rights. Best of Luck
