Has anyone here gotten into an Ivy League grad school from UofT? If so, how?

I’m just wondering if this is even possible. My family is moving to the US and I want to know if I can join them after I graduate, preferably to go to an Ivy League grad school, but do they even accept Canadian undergrad applications? How good does my application need to be? Going to an Ivy League has been a dream of mine forever so I’d appreciate any advice 🙏
