The Up-Top G-Side Crips (or simply G-Siders) are a territorial street gang originating from the Jane and Finch neighbourhood in western boundaries of North York in Toronto, Ontario, Canada. Believed to have been formed in the mid 1990s by high school friends, this gang's moniker comes from the Gosford neighbourhood within Jane and Finch where most of its members had reside at one point. Members of this gang claim the Up-Top Crips card along with the Up-Top Driftwood Crips and Up-Top Shoreshot Crips, although they all operate independently from each other. Authorities believe the G-Siders were involved in an array of criminal offences including attempted murder, firearms trafficking and importation, drug trafficking, robbery, shootings, prostitution and other criminal offences. The G-Siders worked in unison with another gang claiming the Up-Top Crips card called the Young Buck Killas and share many rivals including the South Side Connection Bloods, The Lanes Crew, the Doomstown Rexdale Crips, Tandridge Rexdale Crips and the Stovetop Rexdale Crips.
