Is my two-year academic gap due to business justified for visa purposes, and do I need to provide proof or justification letters for this gap for a Master's?

Yes, a two-year academic gap due to business can be justified for a Canadian study permit, as long as you provide clear evidence and a detailed explanation.

You should include:
- Business registration documents to show your business was active during the gap.
- Proof of your role or ownership (such as partnership agreements or employment contracts).
- Financial records (like tax returns or income statements) if available.
- A gap justification letter explaining your business activities, their relevance to your master's plans, and how they fit your career goals.

Providing these documents helps visa officers see your gap as a purposeful part of your academic and professional journey.
