Sionna

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.
