We present results on the evolution of the z < 1 red galaxy population, as determined from the CNOC2 Field Galaxy Redshift Survey and its associated photometric samples. We will describe a new luminosity function (LF) estimation technique, developed specifically for composite galaxy samples comprised of both spectroscopic- and photometric-redshift data. Application of this LF technique will be illustrated, using large galaxy samples taken from the original CNOC2 spectroscopic- redshift survey and from followup photometric-redshift datasets derived from multicolor UBVRI imaging. In particular, we will show how one can constrain the luminosity and density evolution of the CNOC2 red galaxy population, as well as test the observations against predictions of various spectrophotometric galaxy evolution models.
