The Canada-France-Hawaii Telescope Legacy Survey Supernova Program aims primarily at measuring the equation of state of Dark Energy. It is designed to precisely measure several hundred high-redshift supernovae.

The SNLS survey consists of:

• A large imaging survey at CFHT
  The CFHT Legacy Survey aims at detecting and monitoring about 2000 supernovae with Megaprime at the Canada-France-Hawaii telescope between 2003 and 2008.




• A large spectroscopic survey
  Hi-z spectroscopy of SNe is being carried on 8m class telescopes (Gemini, VLT, Keck). The primary goal is to obtain Supernova identification and redshift. Detailed spectroscopy of a subsample of distant SNe is also done to validate the use of Type Ia SNe as cosmological candles.
