Nopes instead u need to summarize in a line or two what course.... what was the content.... and how its connected to course that u will pursue in Canada.... U can say like dis certificate course covers d gap btwn ur undergrad course and grad course..... and u will be able to successfully complete the grad course in minimum time as u hv already learnt the basics to get an extra edge of the subject..... Remember visa officers are no one but high level HRs.....
