Celestica Inc.
A Canadian electronics maker that designs and builds the servers, networking switches, and storage powering cloud data centers for the world's largest hyperscalers, plus regulated manufacturing for aerospace, industrial, health, and medical markets. Born in 1994 as IBM Canada's manufacturing arm in Toronto, it spun off and was bought by Onex before going public. Its name comes from the Latin "caelestis," meaning "of the sky" — fitting for a company that helps run the cloud.
