While the terms of the deal were not disclosed, it marks the latest effort by Canada Goose to expand its reach into new markets around the globe and beef up its local manufacturing operations.
Under the agreement, Dani Reiss will remain president and chief executive and continue to hold "a significant minority stake" in the company, which prides itself on making all of its winter jackets in Canada.
Canada Goose has hit the accelerator on expansion over the past few years as it responds to a stronger demand for its jackets.
"I believe that we're going to grow substantially," Reiss said in a recent interview with The Canadian Press about the company's future.
"You have to think ahead and you have to look out a number of years," he added. "You have to invest in your infrastructure, your team ... and you have to have a strong strategic planning process."
Founded in a small warehouse in Toronto more than 55 years ago by Reiss' grandfather, Canada Goose now employs more than 1,000 people and its apparel is sold in more than 50 countries.
As part of its image, the company has chosen to keep manufacturing operations in Canada for its apparel, which includes jackets, gloves and winter hats. Canada Goose has also expanded into children's winter wear.
This month, Canada Goose began the final stages of moving to a new factory in Toronto that nearly doubles the size of its workspace to 94,000 square feet.
But staying in Canada comes at a price for both the company and its constomers because of higher labour costs compared with those in Third World countries typically associated with clothing manufacturing.
The jackets generally cost several times more than those of other competitors, which has helped build the company's name as a high-end brand. Canada Goose jackets have been seen in Hollywood movies and on celebrities at the Sundance Film Festival.
