In the time period of 1834-onward until Canada was a nation in 1867, how did one receive designation of a Justice of the Peace. Was this done by application or appointment and if so was it to Britain they made their requests?

[From Cathy] The people that would best answer your question is The Osgoode Society - they are the experts on Ontario's Legal History. The time period you are interested in was one in which many changes happened. They have just published a book answering all the questions you ask. The book is called Magistrates, Police and People: Everyday Criminal Justice in Quebec and Lower Canada, 1764-1837, by Donald Fyson, Professor of History, Universite Laval. See if you can get that on library loan.
