Although I was not asked to take the test and I am not from English speaking countries, my application was OK, maybe because I had enough points, and maybe because my field is teaching English as a second language to university level, which means good English and good communication ability, or maybe because I took my master degree from a Canadian university.
BUT.....I WOULD ADVISE ALL TO TAKE THE TEST AND TAKE NO RISKS, WHY WASTE TIME , WHY MAKE DELAY..BETTER BE ON THE SAFE SIDE.
