A viral video taken at Montreal's Notre-Dame-des-Neiges Cemetery and posted to Facebook on Monday shows long, uncut grass, weeds, and most disturbingly of all, disinterred human remains. 

In the video, since deleted on Facebook but shared elsewhere on social media, Montrealer Pierre Mainville Proïetti says he was visiting his grandfather's grave when he found that a groundhog had burrowed into the neighbouring gravesite and dug up several bones, including parts of a skull.
