Applying to applied mathematics programs as a CS graduate?

I’m wondering whether I have a chance at doing this. I took maths in CS bur they’re probably basic compared to what you would take at a math bsc.

Is this something I can do? I really want to learn more about applied math. Especially about fields like numerical analysis and stochastics.

I would also be an international student. I plan to apply to Canada.

If for any reason I can’t get into math, what should I check for in CS masters programs to learn more about mathematics?

Yes, you can get into a Canadian applied math program as a CS graduate. Here’s the University of Waterloo requirements: https://uwaterloo.ca/applied-mathematics/graduate-students/applying
