This paper is one of a series describing the Canada-France Redshift Survey(CFRS). It is shown how the shape of the continuum around the emission line canbe used to distinguish between [OII] 3727 at z > 0.76 and H$\alpha$ at lowredshift in spectra for which only a single isolated emission line is visible.Based on this, [OII] 3727 is most likely to be the emission line in most of thesingle emission line galaxies in the CFRS. The statistics of the repeatedobservations are analyzed to derive an empirical calibration of the reliabilityof the spectroscopic identifications in the CFRS, to determine how oftenadditional observations could lead to the identification of an initiallyunidentified object and to provide an estimate of the internal velocityaccuracy. Finally, the results of spectroscopic observations of 413 objects inthe 1415+52 and 2215+00 CFRS survey fields are presented.
