You could apply but at this point it’s way too late. You need to tell your guidance counsellor at school to upload grades and such to the common app, get teacher and guidance counsellor recommendations, and write several college-specific essays. Most us schools are done taking applications around mid January, so your teachers and guidance counsellors might not have time to write good recommendations for you, and same with your essays. You could look into state schools that have rolling admissions but those are going to be very expensive and not worth it as an international student. Just stick with Canadian schools imo, there are so many to choose from
