If you'd like to connect your research with a community group, this might be a place to start.
And if you're already working with a community group, they are still accepting proposals for projects — August 15 is their deadline. Contact email for proposals is email@example.com.
SFPIRG also has a number of grants and other resources for SFU students working on social or environmental justice projects or campaigns. Note that the grants are specifically not for "Masters and PhD research at the University."
