You should have talked to the DSO at your school and asked this question BEFORE you decided not to enroll for the Spring semester to quit your classes because it sounds like you are in violation of your status. And if you did, you are removable (deportable). Your F-1 visa stamp only allows you to travel to the US and request admission as an F-1 student. You are in valid F-1 status only as long as you are maintaining status - that's what D/S (duration of status) means. If you quit your studies, you are not maintaining status and the school will report you to immigration. Normally, there is a 60-day grace period after the completion of the course of study or OPT as stated on the I-20. Filing a change of status to B-2 visitor may be an option if you need time to process your visa to Canada. You should consult with an experienced immigration attorney immediately about your options.

My answers are for general information only, NOT A legal advice because these are not tailored to your specific situation. Contact an Immigration Attorney if you need legal advice.
Check with your school first. You are in violation of your F-1 status, but your status will not be terminated until the school reports you and an immigration officer makes a decision in your case.
