Grade 9, 10, 11 and 12 Supply List Ontario (2026-2027)

High school supply lists in Ontario are less prescriptive than earlier grades — but the stakes are higher. The right supplies make the difference between a student who's organized and one who's scrambling. Here's what Ontario high school students consistently need for Grades 9 through 12.

What's on the Ontario High School Supply List?

These items appear across Grade 9–12 supply lists at Ontario high schools:

• Mechanical pencils (3-pack, 0.5mm with lead refills)
• Ballpoint pens (10-pack, blue, black, and red)
• Fine liner pens (10-pack, assorted)
• Highlighters (8-pack — one colour per course)
• Black gel pens (12-pack, for exams and essays)
• White erasers (4-pack)
• Student agenda / planner (2026-2027 school year layout)
• 5-subject spiral notebook (college ruled, 200 pages)
• Loose leaf paper (300 sheets, 3-hole punched)
• 3-inch 3-ring binder (heavy duty)
• Binder dividers
• Sticky notes (4-pack, assorted)
• Index cards (200-pack, lined 3x5)
• Scientific calculator (Casio fx-300 series)
• Backpack (20-inch, waterproof, laptop compartment)

Why the Agenda Matters More in High School

Ontario high school students manage multiple courses, deadlines, and independent study for the first time. A physical planner — not just a phone calendar — keeps everything visible in one place. Students who use a weekly layout planner consistently outperform those who rely on digital reminders alone.

What It Costs to Buy Everything Separately

The full Grade 9–12 list bought item by item across multiple stores typically runs $195–$220 CAD. Add a backpack and you're at the high end of that range.

High School Supply Tips for Ontario Students

• One highlighter colour per course. Assign a colour to each subject at the start of the year. Makes review sessions dramatically faster.
• Bring index cards to every class. They're the fastest way to make flashcards after a lecture while the content is still fresh.
• Buy the agenda before school starts. They're usually sold out at school supply stores by the first week of September.
• Keep a second set of pens at home. Running out of pens the night before an exam is avoidable. A 10-pack covers the full year.
