Abstract:	Type Ia supernovae currently provide the most direct evidence for an accelerating Universe and for the existence of an unknown “dark energy” driving this expansion. The 5-year Supernova Legacy Survey1 will deliver ∼1000 Type Ia detections with well-sampled g′r′i′z′ light curves. Using this definitive dataset, we will obtain a precise measurement of the cosmological parameters (Ωm, ΩΛ); our goal is to determine the cosmological equation of state parameter w to a statistical precision of ±0.07, testing theories for the origin of the universal acceleration. In these Proceedings, we summarise the progress made during the first full year of the survey operation.
