Short-term studies
Students who started short programs (8 to 12 months in length) in the spring, summer or fall 2020 semester may complete their entire program of study outside of Canada and still maintain post-graduation work permit eligibility, provided that they meet all the other applicable program requirements. These students are exempt from the requirement to complete at least 50% of their program of study in Canada and in class. However, time spent studying outside of Canada will only be counted towards the overall length of the post-graduation work permit until April 30, 2021. Any time spent studying outside of Canada after April 30, 2021 will be deducted from the length of the post-graduation work permit.
This is their rule which clearly states that it doesn't matter if we complete our study abroad till apr 2021 but need to be there before apr
