Control investments in profitable businesses with C$5M+ EBITDA and sustainable competitive advantages, where management co-invests alongside TriWest. Fund VI platforms include The Fastener Group, Spence Diamonds, Ocean Brands and AirSprint.
Since 2020 a multi-fund strategy has let TriWest invest in smaller Western Canadian businesses through TriWest Lower Mid-Market Fund I. A second lower mid-market fund was planned for launch by the end of 2025.
An investment framework built around being the 'partner of choice', with principals investing 7.5–15% of each fund's capital personally.

At this size the intake is one or two people and rarely posted on a public careers page: it runs through campus contacts, referrals and direct approaches. Treat the absence of a posting as a reason to reach out rather than as evidence there is no seat. BSO has not confirmed a timetable for TriWest Capital Partners on an official page: this records that the intake exists and what the category's cycle looks like, not a published date. Confirm with the firm before you plan around it.
