  We have conducted an analysis of nebulae around Wolf-Rayet (WR) stars in M33
using data collected by the imaging Fourier transform spectrometer SITELLE at
the Canada-France-Hawaii telescope as part of the SIGNALS Large Program. Of the
211 known Wolf-Rayet stars in M33, 178 are located in the fields observed in
this study. We present the results of this analysis in the form of a
comprehensive summary of all nebulae found around the observed WR stars. Based
on three criteria we find to be the most effective for their detection, we
detect a clear association with a circumstellar bubble around 33 of them
(19\%). Our results show that the presence of bubbles does not correlate with
the spectral type of the central star. The mean diameter of the WR nebulae we
have found is 21 parsecs.
