We use three years of data from the Supernova Legacy Survey (SNLS) to study
the general properties of core-collapse and type Ia supernovae. This is the
first such study using the "rolling search" technique which guarantees
well-sampled SNLS light curves and good efficiency for supernovae brighter than
$i^\prime\sim24$. Using host photometric redshifts, we measure the supernova
absolute magnitude distribution down to luminosities $4.5 {\rm mag}$ fainter
than normal SNIa. Using spectroscopy and light-curve fitting to discriminate
