Enbridge vs TC Energy — two pipelines, two very different bets

The question comes up constantly: Enbridge or TC Energy? Both are large Canadian pipeline operators. Both pay dividends above 5%. Both have been in the infrastructure business for decades. The comparison seems natural.

It is not natural. The two businesses are structurally different, and the difference matters more than the yield.

The business model is not the same

Enbridge is a toll-road operator. It moves liquids — crude oil, natural gas liquids, refined products — through a network of pipelines that are largely contracted under long-term, cost-of-service or take-or-pay agreements. The commodity price does not matter to Enbridge's cash flow. What matters is throughput, and throughput is largely locked in. The Line 3 replacement, completed in 2021, added capacity and locked in new contracts. The U.S. gas utility acquisitions in 2024 added regulated earnings with a different seasonal profile. The business is designed to be boring.

TC Energy is a project-finance machine. It builds large, capital-intensive infrastructure — pipelines, power plants, LNG terminals — and finances those projects with a combination of equity and debt. The underlying assets are regulated or contracted, similar to Enbridge, but the risk profile is different because TC Energy has historically taken on more construction risk, more cost overrun risk, and more regulatory risk than Enbridge has been willing to accept.

The distinction matters because construction risk is not the same as operating risk. An operating pipeline is predictable. A pipeline under construction is a project.

Coastal GasLink is the reference case

Coastal GasLink is the most instructive data point in the comparison. TC Energy committed to build a 670-kilometre natural gas pipeline in northern British Columbia for LNG Canada. The original cost estimate was approximately $6.6 billion. The final cost was approximately $14.5 billion — a 120% cost overrun.

TC Energy absorbed the overrun, wrote down assets, sold equity at a discount, and ultimately spun off its oil pipelines business into South Bow Corporation in 2024 to reduce complexity and debt. The dividend was maintained, but the share price did not recover to pre-overrun levels for years.

Enbridge has not had a comparable event. Its largest recent capital allocation decision — the $14 billion acquisition of three U.S. gas utilities from Dominion Energy in 2023 — was a financial transaction, not a construction project. The risk was integration risk and financing risk, not cost overrun risk.

This is not a coincidence. It reflects a deliberate difference in capital culture.

The dividend track record under pressure

Both companies have maintained their dividends through commodity cycles. But the quality of that maintenance is different.

Enbridge has raised its dividend every year for more than 28 consecutive years. The raises have been modest — 3% to 5% annually — but they have been consistent through 2015, through 2020, and through the Coastal GasLink period when TC Energy's balance sheet was under stress. The payout ratio has been elevated, but the free cash flow coverage has remained adequate because the underlying contracted cash flows are stable.

TC Energy maintained its dividend through Coastal GasLink, but the payout ratio reached levels that made the market uncomfortable. The South Bow spinoff was partly a response to that discomfort — separating the oil pipelines business reduced TC Energy's complexity and improved the optics of the dividend coverage ratio on the remaining gas infrastructure and power assets.

A dividend that survives a stress event is not the same as a dividend that was never under stress. Enbridge's dividend was never under the same stress that TC Energy's was between 2021 and 2024.

The debt load and the cost of capital

Both companies carry significant debt. Infrastructure businesses are supposed to carry debt — the assets are long-lived, the cash flows are contracted, and the leverage is appropriate to the risk profile.

Enbridge's debt-to-EBITDA ratio has historically run between 4.5x and 5.0x, which is consistent with investment-grade infrastructure. The U.S. gas utility acquisitions temporarily pushed leverage higher, but the company has guided toward a return to its target range. The credit rating is BBB+.

TC Energy's leverage increased materially during the Coastal GasLink construction period. Post-spinoff, the company has targeted a debt-to-EBITDA ratio in the 4.75x range on the remaining business, which is comparable to Enbridge. The credit rating is BBB.

The one-notch difference in credit rating translates into a marginally higher cost of capital for TC Energy. In a business where the return on regulated assets is set by regulators, a higher cost of capital is a structural disadvantage.

The growth profile is different

Enbridge's growth is incremental. The company adds capacity to existing systems, acquires regulated utilities, and grows the dividend at a rate roughly equal to the growth in distributable cash flow per share. The guidance for 2026 is 3% distributable cash flow per share growth. That is not exciting. It is predictable.

TC Energy's growth profile is more variable. The company has a large capital program — approximately $7 billion per year through 2028 — focused on natural gas infrastructure and power. The assets under construction include Southeast Gateway Pipeline in Mexico, Gilded Rose LNG in Alaska, and several power projects in Canada. If those projects come in on time and on budget, the growth rate will be higher than Enbridge's. If they do not, the pattern from Coastal GasLink will repeat.

The question for TC Energy is whether the capital culture has changed. The company has new leadership, a simpler structure post-spinoff, and explicit commitments to capital discipline. The commitments are credible. The track record of execution is still being rebuilt.

How the desk reads the comparison

The desk owns Enbridge. The desk does not own TC Energy.

The reason is not yield — TC Energy's yield is comparable. The reason is not valuation — both trade at roughly similar multiples of distributable cash flow. The reason is capital culture.

Enbridge has demonstrated, over 28 years of consecutive dividend increases and through two major commodity downturns, that it will not sacrifice the dividend to fund a project. TC Energy has demonstrated, through Coastal GasLink, that it will take on construction risk that can threaten the balance sheet and force balance-sheet repair at an inopportune time.

That is not a permanent disqualification for TC Energy. Capital cultures can change. The South Bow spinoff was a genuine simplification. The new management team has made explicit commitments to capital discipline that the previous team did not make with the same clarity.

But a demonstrated track record of capital discipline is worth more than a stated commitment to it. Enbridge has the track record. TC Energy is rebuilding one.

When the track record is rebuilt — when TC Energy has executed its current capital program on time and on budget, maintained the dividend without balance-sheet stress, and grown distributable cash flow per share at the guided rate for three or four consecutive years — the comparison will be closer. Until then, the desk prefers the toll road.

The practical question for investors

If you are choosing between the two, the question is not which one has the higher yield today. The question is which one you are more confident will still be raising the dividend in ten years, and which one is more likely to surprise you with a balance-sheet event that forces a reset.

Enbridge is the more boring answer. Boring is underrated in infrastructure.

TC Energy is the more interesting answer. Interesting is underrated in infrastructure too — but only when the execution risk is priced in and the capital culture has been demonstrated, not just stated.

The desk's view is that the market has not yet fully priced the execution risk back into TC Energy after Coastal GasLink. The yield is attractive, but the yield was attractive in 2021 too, before the cost overruns became public. A yield that compensates for execution risk is not the same as a yield that is simply high.

That is the comparison. Two pipelines. Two very different bets.
