Canadian women's wear retailer Aritzia has announced a partnership with private equity firm Berkshire Partners based in Boston, US.

The deal, the value of which was not disclosed, will provide Aritzia with significant investment from Berkshire to help it continue its expansion strategy in Canada and overseas.

All head office operations will remain in Vancouver under the successful leadership of chief executive Brian Hill and the existing management team.

Berkshire and Hill will share control of the board of directors and will look to recruit between two and four additional directors with strong backgrounds in fashion, US and Canadian real estate and corporate strategy.

Hill said: "Berkshire Partners has extensive retail and consumer expertise and will provide valuable financial and strategic guidance as we expand into new markets.

"The opportunities resulting from this partnership, and the growth it will generate, will extend to our existing and new employees, customers, and business partners in the retail industry here in Canada and abroad."

Berkshire managing director Kevin Callaghan said: "Brian Hill has built a recognised industry leader in an extremely demanding industry.

"We believe that Aritzia's superior market position is driven by the company's customer focus, cutting-edge vision, and creative management team."

1984-established Aritzia is a vertical retailer that has seen steady expansion over the last 20 years. The company has 18 stores in key urban centres across Canada.

Berkshire Partners has invested in mid-sized private companies for the past twenty years through six investment funds.
