For years, Montrealers have been puzzled about a distinct olfactory experience near the Institut de Recherches Cliniques de Montréal (IRCM), which some people describe as a smell like "death."\nUPDATE: This article has been updated with a response frm the IRCM.\nA Reddit user on the AskMTL thread asked about the smell in question a few days ago after they noticed it on a bike ride. The smell apparently "permeates the area" south beyond the intersection of St-Urbain and des Pins. It only lingers for a few metres before disappearing as quickly as it appears, they say.\nA flurry of answers unearthed that this odour has been lingering there for decades, according to one respondent. Know one really knows for sure, but some claim that the IRCM lab has something to do with it.\nThe original post (seen below) states that a "very distinct smell" permeates an area of a few metres in front of the IRCM building. Once you pass the building, the smell dissipates.\nWe reached out to the IRCM. In response, they stated that, "after verification, the odour may be related to the Institute's household waste, which is stored at the entrance of the IRCM's indoor parking lot (on Saint-Urbain Street) between waste collection." "The situation was reported to the IRCM's relevant authorities. The Institute will seek to identify and implement measures to correct these inconveniences."\nBut this would not explain why the smell has persisted for years.\nGoogle Maps\nRespondents have described the smell as "death," "sewer gas," and even "shrimp." Apparently, this olfactory assault has been ongoing for years.\nhttps://www.reddit.com/r/montreal/comments/co0hpv/help_me_identify_this_bad_smell_on_sturbain/ from https://www.reddit.com/r/montreal\nReddit users are calling on city hall to send inspectors to investigate the smell.\nStranger Things parallels aside, it's truly amazing that this smell has been there for what some say decades. Strange odours often don't come from a good place, so it's understandable that the public is concerned.\nREAD ALSO: We Asked Montrealers About The Strangest Things They've Ever Seen In The City\nMany people seem to think that the smell is from sewer gases and road work.
