RSM at 100: A Century of Understanding and Insight, Multiplied

RSM Canada proudly celebrates RSM US's centennial—100 years of understanding how businesses grow, compete and adapt

TORONTO, ON – (June 1, 2026) – RSM Canada (“RSM”) – a leading global provider of consulting, tax and assurance services – is proud to celebrate the 100-year anniversary of RSM US LLP, marking a century shaped by helping businesses navigate change.

The milestone, expressed as “RSM¹⁰⁰” or “RSM to the Power of 100,” reflects how that experience is applied today to help clients navigate change and pursue growth.

“RSM¹⁰⁰ is rooted in what we’ve learned from a century of working alongside dynamic, growing companies," said Brian Becker, CEO of RSM’s transatlantic partnership and managing partner with RSM US LLP. “We have built a deep, enduring understanding of how these businesses think, operate and compete. That perspective shapes how we support our clients as they manage increasing scale, complexity and risk.”

In Canada, RSM’s growth has been driven by its position as part of the broader integrated platform with RSM US, following the Canadian firm’s entry into the market in 2017. Through this strong connection, RSM Canada combines deep local insight with the scale, capabilities and infrastructure of the U.S. firm and global network. This model enables Canadian businesses to benefit from global perspective, digital innovation and sector specialization—delivered with local relevance—helping them navigate an increasingly complex environment.

“This milestone reflects the strength and evolution of a firm we’re proud to be aligned with,” said Harry Blum, national managing partner for RSM Canada. “Since entering the Canadian market, our growth has been shaped by that platform—giving us the foundation to scale with purpose and consistency. In this way, we’re able to translate a 100-year legacy into meaningful value for Canadian businesses, helping them navigate complexity and pursue growth.”

RSM’s approach is grounded in its brand promise, the Power of Being Understood, centred on listening first and delivering insight and services that reflect the full context of each client’s business challenges and opportunities. This is especially important for Canadian companies, which are managing increasing economic, operational and technological complexity, while advancing transformation agendas across their businesses.

As it enters its second century, RSM is scaling investments in its people, digital capabilities and global reach to support clients as they grow and adapt. Backed by a US$1 billion commitment to AI and digital, the firm is enabling faster insight and more integrated delivery. It has also established a transatlantic partnership encompassing the U.S., Canada, UK and Ireland with integrated teams in India and El Salvador to provide more seamless global services to clients.

"A hundred years is a remarkable milestone, but what it really represents is the trust middle market businesses have placed in us to help them navigate whatever comes next. Our job is to meet them there, with the talent, digital capabilities and global reach required to prepare today’s growing businesses for the challenges and opportunities of tomorrow," added Becker.
