It's now a parking lot near the Victoria bridge, but it was a mass grave for 6,000 Irish immigrants who died of typhoid fever.
The lot and land are owned by Hydro Quebec, which plans to build a substation at the site.
The utility, which held an information meeting on Thursday, says it wants to work with the community and the city to include a commemorative site.
"As for the substation, it's meant to respond to electricity needs and demands in the area, as well as to help out with the light rail train, but the Irish community has been pushing for years to have a commemorative site built where this parking lot is now. Adjacent to the parking is the Black Rock, which also pays tribute", reported CTV's Matt Grillo.
The Irish community has said it wants a park or even a museum at the site.
