I have 58% in +2 & I will improve through improvement exam up to 62%, will I get admission in Canada for a science-based course?

Hi Darin, Yes, after improvement, if you are able to score above 60 percent marks, then you can get admission in any colleges in foreign countries including Canada as well, in Science courses also. Best of luck.

Yes, at least 60% should be there, so you can apply for the admission.
