Toronto's multibillion-dollar private equity firm Northleaf Capital Partners Ltd. made an investment in healthcare services provider Lifemark Health Corp. to bolster the company's growth.

Privately held Lifemark, which is owned by New York-based venture capital firm Audax Management Co. LLC, provides physiotherapy, independent medical assessments and home care services in Canada.

Northleaf said the investment will support Lifemark's acquisition-oriented growth strategy.

Northleaf's Managing Director Matt Shafer said, "we are excited to partner with Lifemark and Audax to support their successful acquisition strategy and help build a national leader in the Canadian physiotherapy market."
