A legacy of success

The Holdun legacy began with Sir Herbert Holt, who emigrated from Ireland to Canada in 1873. When he arrived to Montreal, he focused much of his energy on the construction of the Canadian Pacific Railway. Soon, Holt switched gears to become a pioneer developer in Quebec’s emerging energy industry. Along with a partner, he founded the Montreal Light, Heat & Power Company, now known as Hydro-Quebec.

He served as the Royal Bank of Canada’s President from 1908 to 1934, and remained a board member until his passing in 1941. His business acumen and wide array of expertise led him to become one of the most powerful influencers in the development of Canada’s modern economy. In his time, he wanted to ensure that prosperity would be preserved for his family for generations to come. Today, we stand as proof of his success.


With 300+ years of combined experience, today’s Holdun family has a wealth of knowledge. Meet the faces behind our success.
