Thank you for your interest in becoming a volunteer mentor


Our Culture

Everyone is welcome here. Our Board, Staff and Volunteers are diverse, as are the communities we serve. We are working to create an inclusive culture, where our Board, Staff and Partners continue to reflect our integrity as an organization. We recognize that this will be a continued journey of learning and unlearning. 

Our Clients & Families

80% of Big Brothers Big Sisters’ clients are experiencing 3-5 Adverse Childhood Experiences, which are forms of social, emotional or economic challenges. Our mentoring programs are interventions, helping empower young people to realize their potential. 

We prioritize program delivery to young people and families in marginalized communities, including Black, Indigenous, Newcomer Youth, Youth In-Care and LGBTQ2S+. 


1. Understand the Time Commitment

While time commitments vary by program type, we typically require a minimum voluntary investment of two hours per week.  

We understand that unforeseen life changes happen; however, please consider if you are fully able to commit for the timeframe associated with your desired program.  We ask you to consider this as early match closure can be harmful to a young person. 

Student Considerations: Note that we rely heavily on post-secondary student volunteers, and accommodate individuals who reside in our catchment area during the post-secondary academic year (typically September to April) 

2. Find a Program that Suits You

Please take a moment to review our programs. Our program portfolio continues to grow to reflect the needs of the communities we serve. Programs take place in one-to-one or group settings, during school hours or outside of them.  

3. Select a Program of Interest

The program of interest you select on your application may change once you learn more about individual programs during your orientation. This is okay! We welcome and encourage you to make informed decisions as you continue on your voluntary journey with us.

I already have a police clearance, can I use this for my application with Big Brothers Big Sisters?

The agency can accept the police check so long as it meets the following criteria:

-it is the original (with seal, or embossment) copy

-it was issued no longer than 6 months ago

-it is the vulnerable sector type screening (versus a standard police clearance)

Does my boyfriend/girlfriend/partner qualify as a significant other reference if we are neither legally married, nor live together?

Yes, we prefer to have a reference for a significant other/romantic partner over a family reference regardless of whether you are legally married, or live together.

My reference does not have an email, which is required to submit the application. What should I do?

If the reference you are providing does not have access to or use an email account, please enter (or something similar). This will inform case manager that no email is available (applications are personally reviewed entered). Please keep in mind that references without emails can take longer to complete.

I do not have a reference from the vulnerable sector, what should I do?

The vulnerable sector includes having worked or volunteered with elderly, children/youth, or individuals with disabilities.

Although this is a preferred reference, if you have not volunteered or worked within the vulnerable sector, you can use a previous or current employment, or volunteer reference outside the vulnerable sector.

If you do not have an employment reference, you can use a teacher (ex. high school teacher, college or university professor).

Once you begin your volunteer application and screening process, one or more of the above frequently asked questions may apply.
