A strong chemical smell wafted across multiple Toronto neighbourhoods last week, and locals have tied the concerning stench to a transit project in the area. Local residents are speaking out about the installation of RapidTO transit priority lanes on Dufferin Street last week, an already-controversial project adding priority red-coloured lanes along a 2.5-kilometre stretch of the artery since Nov. 16. As for the smell, RapidTO maintains that "Open-air application is the recommended method to ensure proper ventilation." "As with any pavement marking installation, there is an expected level of odour while the material is being placed and curing. "While the odour can be unpleasant, the levels experienced outdoors do not pose a health risk to nearby residents or passersby."
