DESCRIPTION:In hierarchical models\, the assembly history of galaxies can 
 be probed through the study of their Low Surface Brightness (LSB) stellar 
 structures\, which are remnants of past interactions and accretion events.
  These LSB tidal features are sensitive to the type of merger that occurre
 d\, but also to the environment and properties of their host galaxies.\nUs
 ing a dedicated annotation tool\, we investigated of the properties of LSB
  tidal features around a sample of 475 nearby massive galaxies located in 
 the Virgo cluster and in the field. We used deep images obtained with the 
 Canada-France-Hawaii Telescope: MATLAS\, CFIS/UNIONS\, VESTIGE and NGVS.\n
 From our database of LSB structures we computed quantitative properties su
 ch as geometry and luminosity using automated aperture photometry. I will 
 present results on the evolution of the fraction of galaxies with tidal de
 bris and the fraction of luminosity in haloes as a function of the mass of
  the host galaxy and of its environment.
