Abstract We present the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS). This survey spans 155 square degrees in five ugriz optical bands incorporating data from the Wide, Deep and Pre-Imaging components of the CFHT-Legacy Survey. Applying our new methodology for data processing, photometric redshifts and weak lensing measurement to bring systematic errors under control, we present robust measurements of weak gravitational lensing and cosmological constraints.
