Canadian billionaire James K. Irving has died at the age of 96.

His death comes just over a month after the death of his younger brother, Arthur.

Along with late brother John, they were the sons of New Brunswick industrialist K.C. Irving, and were among Canada’s wealthiest people.

James Irving was the chairman of the privately owned J.D. Irving, a conglomerate with interests spanning manufacturing, shipbuilding, infrastructure and agriculture.

This year, Forbes Magazine listed James Irving as being worth $5.9 billion, while Arthur Irving was said to have been worth $6.3 billion, making him Canada’s 10th richest person.

The Irving family said in a statement that James Irving died peacefully on Friday in Saint John, survived by four children.

Funeral arrangements will be announced at a later date.
