i used to work in Toronto for a year and crossed the boarders by plane and car many times.
you are not allowed to bring any fruits back from Canada. Not even an orange.
Also, you will need a passport to enter Canada and re-enter the states. They will scan your passport biographic data page and they will know of any record you may have after the scan. Not sure if they care about a felony charge or not, but get ready for more questioning. If you have tattoos, hide them. Don't lie to them. They know more than you think and will pull your car to the search garage if they sense anything fishy.
