SUN and Parkland's merger is expected to create a massive network of fuelling and convenience stores across the Americas, including over 11,000 fuel stations.

The combined company will benefit from complementary assets, enabling an advantaged fuel supply and further diversifying Sunoco's portfolio and geographic footprint.

U.S. fuel supplier Sunoco has struck a $9.1-billion deal to buy Canada-based Parkland, a move that would create the Americas' largest independent fuel distributor but which Parkland's largest shareholder immediately criticized.
