Online Classes for Canadian Curriculum

I'm seeking help to find or create online classes for my three kids (grades 2, 5, and 9) following the Canadian curriculum. Focus areas are English reading and math skills. Classes should be live interactive sessions on Zoom, preferably on Fridays, Saturdays, and Sundays.

Requirements:
- Separate classes for each grade level
- Tailored approach for each grade
- Experience in online education

Budget: $50/month for all three kids

If you can work within this budget, let's discuss further.
