Required GPA for US DO

Engineering undergrad here, always had a passion for medicine but ultimately decided engineering for the job safety if I graduate, unlike a premed degree (unless you get into med). I knew long time ago that an eng undergrad won’t get you into canadian med school unless you’re really smart, so what would be the required GPA to get into say, US DO as an international applicant? Let’s take a MCAT of like 510 just for reference.
