IELTS score of overall 6.0 no band less than 6.0 is mandatory for international students to study in Canada. TOEFL/PTE is accepted in universities. Canadian colleges and universities do not accept applications without IELTS TRF score card.
Due to Covid-19, Duolingo English Test (DET) is being accepted; it is an hour home test. This is only for Sep’20 and Jan’21 applications.
However, for visa there is no clarity. If a student wants to apply under SDS category, ielts will need to be taken. Maybe with DET he can apply under General category.
Canada has 3 intakes ie January, May and September . One should start the admission process atleast 8 months before the course start date.
