Abstract: We have started a survey of M 33 in order to find variable stars and Cepheidsin particular. We have obtained more than 30 epochs of g-r-i- data with theCFHT and the one-square-degree camera MegaCam. We present first results fromthis survey, including the search for variable objects and a basiccharacterization of the various groups of variable stars.
