Are there Big Brothers Big Sisters locations in every province and territory?
Big Brothers Big Sisters agencies operate in communities across most Canadian provinces as well as Yukon, but there is not necessarily a physical Big Brothers Big Sisters office in every province, territory or city. Some agencies also serve neighbouring communities well beyond the city where their main office is located.
If your community is not listed in this CharityAxess directory, use the Big Brothers Big Sisters of Canada national agency finder or contact the closest regional agency to ask whether your city falls within its service area.
How do I find the Big Brothers Big Sisters location closest to me?
Start with the province where you live and look for the nearest Big Brothers Big Sisters agency or regional office. The closest physical office is not always the only agency that can serve you because many agencies provide mentoring programs across several neighbouring cities, towns and municipalities.
Before visiting an office, check the agency's official website or contact the organization directly. Some locations operate by appointment, some addresses are primarily used for administration or mailing, and mentoring programs may take place in schools or other community locations.
Do all Big Brothers Big Sisters locations offer the same programs?
No. Programs can vary between Big Brothers Big Sisters agencies. Depending on the community, an agency may offer one-to-one community mentoring, in-school mentoring, group mentoring, youth programs or specialized mentoring initiatives.
Parents, caregivers, young people and prospective volunteers should check with their local agency to confirm which programs are currently accepting participants.
Can I volunteer at a Big Brothers Big Sisters location?
Yes. Big Brothers Big Sisters agencies across Canada recruit volunteers for mentoring and other roles. Requirements, available programs and application processes can differ by agency. Visit the official website of the agency serving your community for current volunteer opportunities.
