Canadian student preparing to apply to Ivy League

Hi, I’m a Canadian high school student going into grade 11 this year. I’ve held a 92% grade average in both grade 9 and 10.
My ECs include being the school TV news anchor, grade 9 tour guide, vocal ensemble, cheerleading team, and a part time
job in retail. I plan to apply to Princeton for my undergrad, along with applying to two other Canadian universities as a backup. I just wanted to ask what my chances would be and what can I do to prepare in my grade 11 and 12 years to better my chances? Sorry for the long post. I’m new to this forum, thanks!
