Labatt Breweries of Canada says it is investing $460 million between 2017 and 2020 to enhance its operations and help boost growth.
The maker of popular brands such as Labatt Blue, Budweiser and Alexander Keith's says the figure includes $62.2 million towards brewery operations this year.
Each of Labatt's six breweries has already received at least $19 million in recent years, as it invested $546 million in capital improvements between 2011 and 2016.
The company says this investment in new technology and equipment should help it increase production of new and innovative products, as consumer tastes develop and demand is rising for different kinds of beverages.
The investments are not expected to result in new jobs or layoffs.
Labatt employs more than 3,500 people in Canada and will celebrate its 170th year this fall.
