Experiences from US ADN RN's working in Ontario

Hi
Just wanted to see what experience most US educated Associate degree RN's have had to try and move and practice nursing in Ontario ? What are the normal options CNO gives you to practice/upgrade.

Some things I could think of are

1) Allowing US RN's to give the RPN board exams and practice as an RPN without any additional education ?

2) Allowing the US RN to take a RN--> BSCN course and then give the RN boards ? How long does that take ?

How strict is CNO on this ? Any American nurses who have actually gone through the process ?
