Calgary-based NOVA Chemicals has a new ownership group — but the people calling the shots for the company and its 2,500 employees will still be on the other side of the world.

NOVA was founded in 1954 as a Crown corporation formerly known as the Alberta Gas Trunk Line Company Limited to manage Alberta’s natural gas collection. It later diversified into petroleum and petrochemicals. In 2009, Abu Dhabi state-owned investment firm Mubadala purchased NOVA.
