President’s message

Enbridge executive Colin Gruending

Colin Gruending
Executive Vice President &
President, Liquids Pipelines,
Enbridge Inc.

Every day we add value for our broad customer base.

Our integrated system connects producers to key markets and refiners to critical feedstock, and we remain committed to our foundation—to deliver safe and reliable solutions to our customers.

In 2022, we’ll continue to serve our customers by focusing on:

Safety and reliability

Our liquids system has a proven track record of delivering solutions and outstanding service, while maintaining a strong commitment to safety and operational reliability. We have delivered the Line 3 Replacement Program, which is now in full service. This reflects our successful performance, prudent investment, team vigilance and effective health protocols throughout this project and during the pandemic.

Optimizing throughput

Prior to Line 3 being replaced, we’ve efficiently added incremental capacity on the Mainline of 400,000 barrels per day (bpd) through optimization initiatives. In December 2021, we delivered a record Mainline volume of 3.135 million bpd and have fully restored capacity for our customers with the completion of Line 3 (now Line 93). Line 93 has also provided the industry with much needed egress during a robust commodity price environment. In the oil sands, we’ve also added capacity for producers to grow into. We stay focused on maximizing volume and operating efficiencies to increase throughput on all our assets.

Mainline tolling

We’re focused on the Canadian Mainline System’s tolling agreement and are re-engaged with stakeholders on negotiations. We’re confident we’ll find the right risk-reward balance with customers on the Mainline tolling framework.

Line 5

We’re committed to making a safe pipeline even safer and will continue to pursue the Line 5 Great Lakes Tunnel Project in Michigan. This strategic project is an economic and energy lifeline on both sides of the border, serving critical markets and providing more stability for egress. We expect the permitting review processes to continue throughout 2022 and we’ll continue to operate Line 5 safely.

Growth opportunities

Our growth strategies are efficient, executable, and disciplined. We’re providing more access to southern markets with the expansion of Express Pipeline, Flanagan South Pipeline (FSP) and Enbridge Houston Oil Terminal (EHOT). Our system is poised to meet the additional need for connected infrastructure.

We acquired the Enbridge Ingleside Energy Center (EIEC) from Moda, adding North America’s largest energy export facility to our portfolio. EIEC advances our U.S Gulf Coast export strategy and provides our customers with efficient export solutions from growing Permian and Eagle Ford supply.


Our Environmental, Social and Governance (ESG) goals are ambitious. We see low carbon infrastructure as an important growth platform for our business. We are focused on both lowering our own emissions and investing in ways to help decarbonize our customers and other emitters. Carbon capture utilization and storage (CCUS) will be a big piece of that puzzle, and Enbridge is well positioned to support that buildout.

Our employees take great pride in understanding your business drivers. We’re dedicated to continuing to add value for our customers by helping you meet current and growing demand for energy.

We appreciate your business and trust in our team.

Meeting the needs of our customers

Providing safe and reliable solutions for our customers is our foundation.

For more than 70 years, Enbridge has grown from a single pipeline to the largest, longest and most complex petroleum pipeline system in the world; delivering over 3 MMbpd to markets in Canada and the U.S. Our relationship with our customers and commitment to our industry remain our top priorities, and we continue to deliver solutions that meet customers’ needs and drive growth in our Liquids Pipelines business. Our assets and expertise are well positioned to provide value to customers by delivering infrastructure projects near supply basins, increasing available Mainline capacity and improving on market access to meet the growing needs of the industry while continuing to reduce the systems’ carbon intensity. We will continue to publicly advocate for the responsible growth of the energy industry given the increasing demand for cost-effective and reliable energy on a global basis.

We are listening to the needs of our customers and looking ahead to anticipate market demands with the objective of providing transportation solutions that are cost effective, efficient and timely. In the second half of 2022, we are planning a customer satisfaction survey to gain further insight into the key drivers of our customer needs.

With six separate pipelines connecting Western Canada to the U.S. and further to Eastern Canada, we offer our customers economy, flexibility, reliability, safety and innovation in delivering their products to market.

Our focus is to continue optimizing our expansive network of assets to provide customers with additional capacity and superior service. With the completion of the L3RP, Enbridge believes that low-cost staged options to expand our Mainline capacity through highly executable solutions with proven capabilities dealing with regulatory requirements which provide ample opportunity for us to continue to bring significant value to our customers. Enbridge remains committed to finding creative solutions for providing highly competitive transportation options to premium markets in North America, while also focusing on creating competitive alternatives for our customers to access international markets.

Enbridge is challenging the Michigan governor’s unlawful attempt to close the Line 5 dual pipelines at the Straits of Mackinac by terminating an easement that has been in existence since 1953. We have received strong support for the continued safe operation of Line 5 at the Straits—support that is rapidly gathering momentum from all levels of government, unions, business and industry on both sides of the international border.

In all the years of change and growth, one certainty has remained; delivering safe and reliable solutions for our customers is our foundation. This is why we will continue to vigorously defend our assets from parties looking to inhibit the service we provide our customers. Further, Enbridge is committed to providing increased optionality for our customers while continuing to deliver the exceptional service our customers have come to expect from us.
