The Large Program: Next Generation Virgo Cluster Survey (NGVS), is a mosaic survey using CFHT-MEGAPRIME camera running from 2009 to 2013. The NGVS science goals include not only galaxies and clusters, but also detection and tracking of solar system objects. The NGVS observational strategy enables the project to discover high inclination Trans-Neptunian objects(TNOs). Our discovery pipeline makes use of Elixir processed images, rectified using MEGAPIPE, differenced using 'Diff-Enging' (derived from the CFHT-SNLS project) and then the PS1 MOPS system. The second year data is being processed. In the first year, 26 TNOs (+1 Cenatur) were found in the NGVS observations. Here we present a description of our pipeline along with the TNOs found in first two years observation, comparing our measured size distribution with other surveys and models.
