What are Ontario's 40 volunteer hours?

Ontario students need 40 hours of community involvement activities to earn the OSSD. The province says students can start collecting hours in the summer before Grade 9.

Your school board sets the process for recording, submitting and approving hours, and your principal reviews planned and completed activities. If you are under 18, a parent or guardian must sign your record of volunteer hours.

Read the official Ontario guidance

How to choose an opportunity for your hours

Check the activity

Understand the role, age requirements, dates and commitment before you apply.

Check your school rules

Your school board and principal determine whether the activity fits Ontario community-involvement requirements.

Check your age

Use organiser-stated age information rather than assuming every volunteer role accepts high-school students.

Keep your record

Save the dates, time and useful evidence so you are not rebuilding the experience later.

Questions Ontario students often have

Can I start before Grade 9?

Yes. Ontario says you can start collecting community-involvement hours in the summer before you enter Grade 9.

Do all volunteer activities count toward the 40 hours?

No. Ontario lists eligible and ineligible activity boundaries, and your school board and principal apply the process. Confirm before relying on an activity for your hours.

Can online volunteering count?

Do not assume it automatically counts. Check the activity against your school board's rules and confirm it through your school's approval process.

Do my parents need to sign?

If you are under 18, Ontario requires a parent or guardian to sign your record of volunteer hours.
