Organizations that encourage or help people to volunteer for non-profit groups:
Volunteer BC
Volunteer BC helps coordinate and educate volunteers across BC. They have a number of volunteer centres, including several in Vancouver and the surrounding municipalities, which offer resources to volunteers, such as up-to-date listings of local volunteer opportunities.
Pan-Canadian Youth Opportunities Platform
This is a Canada-wide website funded by the federal government that helps youth to determine what kind of volunteer opportunities are a good fit for them, as well as providing a searchable database of volunteer opportunities by community and cause.
GoVolunteer.ca
This has a geocoded map of volunteer opportunities for interested parties to search through.
List of agencies, boards, and commissions that are appointed by the provincial government:
The Crown Agencies and Board Resourcing Office
keeps a directory of agencies that might be of interest. They don’t explicitly state that all of these organizations are appointed by the provincial government, but I believe that it is the case. It’s also worth noting that some of these agencies require applicants to have significant experience in the area the agency focuses on, so some of these agencies may not be a good fit for youth volunteers.
For provincially appointed agencies, the above-mentioned Crown Agencies and Board Resourcing Office has a searchable database of open positions, which can be limited to just postings in Vancouver. There is also some additional information on serving on provincial boards available here.

A number of Metro Vancouver municipalities post vacancy lists for their committees and advisory boards, although some just list all the agencies that exist, and make applications available without specifying about existing vacancies.
