Are you from a native English speaking country? I guess no. Now as they said, chance of rejection is higher than acceptance as mode of lectures in Canada is English. Now in class, you must communicate with English and your speaking is very low at 5.5, so VO might wonder, how then will you be able to communicate and others able to hear you. Then reading again is way low. VO will still wonder how you can be able to read when your IELTS reading is low. So please do not delay your application by arguing but jst go for another IELTS to improve your score. But still the decision is yours and luck can be on your side and you get approved. All the best bro
