Abstract
Cosmological reionization ends at redshifts around 6. Reionization is a highly
inhomogeneous process, and therefore many sightlines are needed to get
an accurate picture of the ionization state of the high redshift IGM.
We have nearly completed a wide-field optical imaging survey with MegaCam
at the CFHT of 900 sq deg with the goals of finding z~6 quasars and
ultracool brown dwarfs. We have so far spectroscopically confirmed thirteen z~6 quasars
and expect many more within the area observed so far. We request time with
GMOS-North to obtain optical spectroscopy of more quasars from our survey to
confirm their quasar identity and determine redshifts.
