08:41 AM EDT, 04/22/2026 (MT Newswires) -- BCE (BCE.TO) and Celestica ( CLS ) , both higher in U.S. pre-market trading, with Celestica ( CLS ) at an all-time high, Wednesday announced a collaboration to develop a Canadian sovereign artificial intelligence (AI) infrastructure stack.

The collaboration combines Bell's full-stack AI offering, anchored by its national fibre network, data center infrastructure, software, and cloud capabilities, with Celestica's ( CLS ) hardware supply chain for sovereign AI infrastructure, a statement said.

"A trusted, sovereign AI ecosystem can't be built by any one company alone - it requires infrastructure, secure facilities and trusted supply chains working together. Through Bell AI Fabric, we have been building a Canadian ecosystem to support sovereign AI, and our collaboration with Celestica ( CLS ) strengthens that foundation by bringing traceable, lifecycle-managed infrastructure into the stack," said Michel Richer, president, Bell AI and Bell AI Fabric.

BCE shares were last seen up US$0.29, to US$24.19 in New York trading, while Celestica ( CLS ) shares were up US$8.98, to US$412.00, an all-time high.
