TELUS Corporation (TSX:T, NYSE:TU) and BCE Inc. (TSX:BCE, NYSE:BCE) are both betting on artificial intelligence infrastructure, but at very different scales. BCE, through its Bell AI Fabric strategy, is pursuing large data centre capacity, including a non-binding memorandum of understanding to add up to 900 megawatts in Saskatchewan for a potential 1.2-gigawatt hub. TELUS has taken a smaller, more contained approach, starting sovereign AI compute at its Rimouski and Kamloops data centres with 38 megawatts of secured power coming online through the end of 2028. Both companies are pursuing AI while trying to reduce debt, so the size of each bet matters for their balance sheets.

BCE's Bigger Swing With Bell AI Fabric

BCE's third-quarter 2026 results, released on November 6, showed AI-powered solutions Revenue growing 41 per cent, helping Bell Business Markets revenue rise 9.2 per cent. The company has also signed a memorandum of understanding with Cisco on sovereign AI infrastructure, and Bell Cyber deployed a sovereign AI model for Cybersecurity with Cohere.

The Saskatchewan memorandum is the largest element. BCE updated its 2026 guidance on March 16 to reflect a Saskatchewan AI data centre, and the effect is clear in its Capital plans. Capital intensity guidance rose to about 20 per cent of revenue from below 15 per cent, and 2026 free Cash Flow guidance fell to $2.1 billion to $2.3 billion from $3.3 billion to $3.5 billion. In the third quarter alone, capital spending rose 49.3 per cent to $1.33 billion, and free cash flow fell 14.9 per cent to $854 million.

BCE's AI work also reaches beyond its own buildings. HIVE Digital Technologies (TSX:HIVE) said in its November results that it has an arrangement worth about US$225 million over three years supporting Bell AI Fabric and Cohere, which suggests Bell is also sourcing compute from partners.

TELUS Takes a Measured Approach

TELUS has scaled its AI ambitions to fit a tighter balance sheet. On its November 6 call, management said it expects about $500 million of cumulative revenue over three years from its sovereign AI work, with a pipeline of more than $1 billion in contract value. Navin Arora, who leads its global platform businesses, explained that an earlier, larger AI target had included TELUS Digital, which has since been removed from that figure.

TELUS also plans to connect other operators' data centres to its PureFibre network, with customers funding the build upfront, which limits its own capital needs. Larger powered-shell projects are being explored through partnerships and are not included in the $500 million figure. Full-year 2026 capital spending guidance is about $2.6 billion, and chief financial officer Gopi Chande said core capital spending is expected to decline in 2027.

How the Core Businesses Compare

AI remains a small part of each company. Their wireless and internet businesses still drive most cash flow.

TELUS added 84,000 mobile phone customers in the third quarter, with blended churn of 1.01 per cent, its lowest in about three years, and average revenue per user steady at $57.22. Dave Fuller, president of TELUS Communications, said the gains were "definitely not price-based." Adjusted EBITDA fell five per cent to $1.8 billion, and the company reported a net loss of $660 million after an $800 million non-cash Goodwill Impairment on TELUS Health.

BCE added 24,110 postpaid mobile customers, with postpaid churn of 1.06 per cent, while blended average revenue per user fell 1.7 per cent to $57.07. It added 67,199 fibre internet customers across Canada and the United States, where its Ziply Fiber business generated $238 million of revenue. Revenue rose 2.2 per cent to $6.18 billion, and adjusted EBITDA rose 0.9 per cent to $2.79 billion.

Debt and Dividends Shape How Far Each Can Go

Both companies are under pressure to reduce leverage. TELUS reported net Debt of 3.6 times adjusted EBITDA at September 30 and targets about 3.0 times or lower by the end of 2028. It reset its quarterly Dividend by 55 per cent to $0.1875 per share in July, removed its Dividend reinvestment plan discount from October 1 and launched an efficiency program aimed at about $900 million of annualized cash savings by the end of 2028. It is also selling assets, with one TELUS Health business in advanced talks.

BCE targets net debt Leverage of 3.5 times by the end of 2027. After the quarter, Bell agreed to sell a 49.9 per cent stake in a new wireless tower company to La Caisse for $2.45 billion, subject to adjustments, while keeping control. BCE's quarterly dividend is $0.4375 per share, payable January 15, 2027.

BCE's larger AI build-out increases its capital needs at a time when free cash flow is falling. TELUS's approach limits its spending but also limits how much AI can contribute in the near term.

Risks to the AI Strategies

The Saskatchewan memorandum is non-binding, so its size and timing could change. Large AI data centres depend on securing power, long-term customers and financing, and returns can take years. If Demand for sovereign AI compute in Canada grows more slowly than expected, the capital already committed could weigh on returns.

For TELUS, the risk is that a smaller program does not do enough to offset slow growth in legacy services and weaker results at TELUS Digital. Both companies also face wireless pricing pressure, regulatory decisions on network access and the execution risk of major cost-cutting programs.

Conclusion

BCE and TELUS both see AI infrastructure as a growth opportunity, but they have chosen different scales. BCE is pursuing a potential gigawatt-scale hub and accepting much higher capital spending and lower free cash flow in 2026. TELUS is building around existing data centres and partner funding, targeting about $500 million of revenue over three years while it cuts debt. The next checkpoints are TELUS's 2027 guidance in February, progress on BCE's Saskatchewan plans and how quickly each company converts AI pipelines into signed contracts.
