Hugo Meunier, a Radio-Canada Grand Montréal presenter, aired a segment on Wednesday evening after a listener raised concerns about a rapidly spreading weed in the Plateau‑Mont‑Royal neighbourhood. Joined by colleague Monic Néron, Meunier investigated how the plant’s expansion appears to be intensifying seasonal allergy symptoms among local residents.
The investigation focused on the recent proliferation of the weed, which has become a noticeable feature of streets, parks and private gardens across the Plateau. According to the hosts, the plant’s pollen is suspected of aggravating the typical hay‑fever season, leading to heightened discomfort for people already prone to allergies. The segment highlighted observations from neighbourhood residents who reported more frequent sneezing, watery eyes and nasal congestion since the weed began to dominate the local flora.
Meunier and Néron traced the weed’s spread through on‑the‑ground reporting, documenting its presence in multiple blocks and noting its resilience in the city’s micro‑climate. While the broadcast did not provide scientific measurements, the hosts emphasized the correlation between the weed’s visibility and the uptick in allergy complaints reported by listeners. They also referenced the broader public‑health context, reminding audiences that seasonal allergies affect a significant portion of Montreal’s population each spring and summer.
The segment concluded with a call for residents to monitor the plant’s growth in their own yards and to share observations with local health authorities. By bringing the issue to the airwaves, Meunier and Néron aimed to raise awareness of how changes in urban vegetation can have direct health implications for the community.
Radio‑Canada Grand Montréal plans to follow up on the story with further reporting, including potential interviews with botanists and public‑health officials, to better understand the weed’s impact and possible mitigation strategies.
