We’re growing: The Esso Commercial Cardlock™ network continues to expand across Canada. Between 2017 and 2019, more than 80 former standalone Husky cardlocks and Husky cardlocks at Husky Travel Centres were re-branded Esso. And new Esso cardlock and travel centre locations continue to be added to the network. As of today, there are more than 160 Esso cardlocks in eight provinces from coast to coast. Find an Esso cardlock near you.

More than just a fill-up: At more than 50 Esso cardlock travel centres across Canada, drivers can park their truck and visit the restroom, grab a snack or a meal, and take a shower. Where available, drivers can also do their laundry or take it easy in a comfortable lounge.
