  We present optical spectra of 144 white dwarfs detected in the
Montreal-Cambridge-Tololo (MCT) colorimetric survey, including 120 DA, 12 DB, 4
DO, 1 DQ, and 7 DC stars. We also perform a model atmosphere analysis of all
objects in our sample using the so-called spectroscopic technique, or the
photometric technique in the case of DC white dwarfs. The main objective of
this paper is to contribute to the ongoing effort of confirming
spectroscopically all white dwarf candidates in the Gaia survey, in particular
in the southern hemisphere. All our spectra are made available in the Montreal
White Dwarf Database.
