The province’s Ministry of the Environment is investigating a sulphur-like odour that has been detected in east Hamilton.
Coun. Sam Merulla said he notified the ministry about the smell after he received several complaints on Wednesday and Thursday nights.
Reports came from residents living "as far west as Victoria [Avenue], as far east as Stoney Creek, and up to the Mountain,” he said.
Jennifer Hall, a spokeswoman for the ministry, told CBC Hamilton on Friday that investigators interviewed residents on Thursday night.
"At the time that our staff arrived arrived, major sulphur odours could not be confirmed," she said.
“We are consulting with companies in the area to look into the source of the odours.”
