What program would help me become a quant? - High school student

Hey everyone, just to let you know, this is my first post here, and I'm open to any feedback
So I'm a high school student in Canada, Ontario going into grade 12 next year, and I'll have to apply to universities around october - novermber ish..

After uni, I wanna become a quant, like a quant trader, so I have gathered a few programs that I feel like would point me in the right direction

University of Waterloo

- Math (Applied, Pure, etc.)

- Computational Mathematics

-Computing and Financial Management (CFM)

- Data science

-Mathematical Finance

-Math/FARM

University of Toronto - UTSG

- Math (Applied, Pure, etc.)

- Data science

-Engineering Mathematics, Statistics, and Finance

- Mathematical Applications in Economics and Finance

Wilfrid Laurier

- Double degree BBA (Laurier) Math (uwaterloo)

- Financial Mathematics and Analytics

These are the unis I'm aiming for next year. What programs are gonna steer me towards becoming a quant? Any tips or suggestions are welcome.

P.S. Thinking of becoming a quant in Toronto, and how hard is it to go into the US to get a quant job with a Canadian university degree?

thanks !!
