Among the four science instruments that will fly onboard the James Webb Space Telescope (JWST) in 2018 one - NIRISS - is entirely canadian. The Near InfraRed Imager and Slitless Spectrograph is equipped with a cross-dispersing grism that was specifically designed to obtain spectroscopy of transiting exoplanets across the 0.6-2.8 microns range at R=700. Transit spectroscopy of hot Jupiters, super-Earths and even Earth-like planets is within reach of NIRISS. I will present the instrument capabilities in that specific mode as well as simulations of our expected performances for selected science targets.
