Ontario RPN (Operating Room)

I'm a new resident in Ontario and took the RPN exam. I'm waiting for my result but I wanted to know about the job opportunuties I need and the necessary information in order to work in the Operating Room. My background before is I'm an experienced operating room nurse for 4 years in my country. I have no idea if my experience before will be qualified here in Canada. For all RPNs who have an idea or any important advice pls share and help. Thanks in advance and looking forward for replies.
