Why Supplementary Applications Matter for International Students
For international students applying to Canada’s top universities, a strong academic record is not enough.

These supplementary materials are often the deciding factor for competitive programs such as:
- Western Ivey AEO
- York Schulich BBA
- Queen’s Smith Commerce

Common Mistakes International Applicants Should Avoid
- Generic or Cultural Misalignment
Canadian schools are open to diverse contexts, but vague answers like “I’m passionate about business” fall flat. Explain the impact of your leadership in detail, even if it happened in a local youth group or family setting. - Overwriting or Underwriting
Stick to the word count. Writing too little shows lack of engagement; too much may be penalized by automated systems. - Ignoring Optional Sections
Don’t skip Laurier’s ABS or Ivey’s video essay just because it’s optional. Many successful international applicants include them for a competitive edge. - Time Zone Errors
If a portal closes at 11:59 PM ET, submitting from Vietnam at 11:00 AM your time may be too late. Always convert carefully and aim to submit 24 hours early. - Overemphasis on Academics
Admissions teams already have your transcript. Use the supplement to emphasize your personality, values, and ability to thrive in group or leadership settings.
University-Specific Strategies for International Students
🏛 Western Ivey AEO
If you’ve led a nonprofit initiative, helped in your family’s business, or run a community campaign — explain the leadership, not just the activity.
Use the Ivey STAR method (Situation → Task → Action → Result) for both the written and video portions.
🏛 York Schulich BBA
For the leadership profile, include up to 5 activities from high school. International students can list:
- Community tutoring
- Entrepreneurial ventures
- Cultural club leadership
- Model UN in your country
🏛 U of T Engineering
Video interview is strictly timed. Use Myls Interview to practice answering questions such as:
- “Describe a time you solved a technical problem.”
- “What would you do if your team disagrees with your solution?”
🏛 Waterloo AIF
Focus on depth over quantity. If you did one impressive research project, explain it well. For optional interviews (sometimes available via Unibuddy), it’s worth preparing even if you’re unsure it will be used.
