1. they are requiring the course syllabus that is why you got that email. I got your point about that, it is your own discretion if you would want to submit a syllabus or not. If not, they are going to assess your nursing education based only on the documents they have, you need to notify them that you just want to be assessed with your course description. Or as far as i know, it was stated and mentioned in the email that if they didnt received any further nursing education documents, they would assess based on what they have.
2. Once your advisory report was issued, you can see it in your nnas dashboard and there is a button or link there that would direct you to appply with CNO, then you need to pay for the application fee and your application number will be given to you
3. Safe practice for ontario is 3 years from the last time you had your nursing practice/employment
4. Yes you can apply to CNO even if you are not yet here, because CNO takes forever lol! Minimum of 5 months before you get a decision from the college. But it is up to you, maybe you can apply with cno once you are already sure that you are coming here.
