Canon T6s has a Canon EF/EF-S lens mount and currently there are 333 native lenses available for this mount.
The latest released lenses that are compatible with the T6s are the Carl Zeiss Makro-Planar T2/50, the Tokina 35mm f2.8 Macro DX and the Canon 50mm f2.5 Macro.
Canon T6s doesn't have a sensor based image stabilization system but 113 of these lenses already comes with optical image stabilization.
Since Canon T6s has a APS-C sensor, it has a focal length multiplier of 1.6x so you have to multiply lenses original focal length with this multiplier to find the Full Frame equivalent focal length of the lens when mounted on T6s.
