"Our intention is to build a modern high performance brewery fit for Canada while relying on the world-class talent and expertise found here at home in Quebec," Frederic Landtmeters, president and CEO of Molson Coors Canada, said.
“The original Notre-Dame Street facilities are no longer suited to extensive modernization of our equipment and processes."
The brewer expects the proposed project be completed and in operation by 2021 and cost C$500 (US$389m) if its plans are accepted by the city.
"As we look to our next 230 years, we need to make substantial investments in our people and our operations. Today's decision to move forward will enable us to stay competitive in an evolving market."
Molson Coors Canada’s offer will be presented to Longueuil’s city council for approval on Dec. 5, 2017, according to Longueuil Mayor Sylvie Parent.
"There are still a few steps to go before a potential groundbreaking event in 2018. We are also extremely pleased that a flagship like Molson Coors has chosen to remain in the greater metropolitan area for this new and important stage in its 200-year history," Parent said.
Plans for original Montréal site
The mega brewer announced its plans to build a new facility rather than upgrade its Montréal site in July 2017.
CBC News reported that the Mayor of Montréal Valérie Plant said that the city tried to convince Molson Coors Canada to maintain its main brewery in Montréal making them an “improved” offer but the company had already made its decision.
Molson Coors Canada said its original Montréal facility along the St. Lawrence River will undergo an “urban development project,” and that it will “remain an invaluable legacy for the city and for Molson Coors.”
The brewer said in July that the Montréal will be home to a microbrewery and beer museum.
"As North America's oldest brewer, our roots will always be in Montreal,” Landtmeters said.
