The investment aims to support product innovation and enable more effectively development of new products.
The firm said it is the only packaging line offering this flexible production capacity and was installed in response to “evolving consumer demand for a greater variety of packaging and will serve as an incubation line for innovative new formats.”
Its key differentiating feature is the option to add capabilities to fill and package different types of containers, allowing for a range of future packaging innovations, they added.
The Widemouth bottle made of 100% recyclable aluminum, will be the first format produced on the line for Coors Light, Molson Canadian and Coors Light Iced T.
The bottle can be resealed after opening and will be available across Canada from this month.
Cathy Noonan, chief supply chain officer, Molson Coors Canada, said: "This major investment in the modernization of our brewery speaks to our commitment to innovation.
"We'll be able to develop new products more effectively, so we can focus on creating industry-leading packaging formats for our Canadian consumers."
The installation follows other investments, such as the addition of fermentation tanks to the plant early last year, translating into capital investments of nearly $90m in Ontario since 2010.
"Innovation is key to creating jobs and strengthening the economy," said Brad Duguid, Minister of Economic Development and Innovation, who attended the official opening.
"Ontario welcomes Molson Coors Canada's commitment to bringing new products to customers while growing its manufacturing capability in Toronto."
Molson Coors is a global brewer with a portfolio including Coors Light, Molson Canadian, Carling, Blue Moon, and Keystone Light.
