Helping clients achieve their goals by pursuing excellence and embracing our passion for the craft of investing

In 2002 Kim Shannon embarked on a journey to build an independent and privately owned firm, focused exclusively on researching and investing in Canadian businesses.

Today Sionna uses that same proprietary relative value approach – which they believe is particularly suited to the Canadian marketplace – to identify and invest in Canadian companies deemed to be trading at attractive prices (relative to value), are poised for growth over the long term, and pay strong or growing dividends.

Sionna joined forces with Bridgehouse Asset Managers to offer the Sionna portfolios to individual investors, through Canadian advisors.
