Hi nisha
i was in ontario before coming to BC. the requirement for crne in ontario is 7 in each module of ielts wth academic version. Yes they can allow you to sit for crne if your ielts score is not so much less than the requirement, suppose u got 6 or 6.5 in writing then they can allow you, but you muct have 7 in listening and speaking. once you cleared your crne to get license you have to clear IELTS and then complete the required prctice hours to get license.
here in BC its all opposite though easy and fair on one side. you should have L-7.5, S-7, W-7 R-6.5. then you have to sit for SEC that is assessment test for International Nurses. once you cleared SEC they will give you a temporary license to coplete 255 hrs of practice that is around 1 month. AFTER all this requirement one apply to CRNBC for CRNE. then it is easy to clear test and get license and start practicing as soon you get license and job.
rest you can chck on CNO site for CRNE in ontario.
