    Kepler Communications brings space-based data centres online

    Toronto-based Kepler Communications announced it has activated the first commercial low-Earth orbit satellite constellation delivering real-time space-based computing to commercial and government customers. Each satellite in the network is equipped with optical terminals enabling laser links between space, air, and ground assets, allowing data to be processed directly in orbit rather than waiting for downlink to Earth. The system reduces latency, enables AI processing, and supports autonomous space operations. Kepler said it will expand the global optical relay network in 2028 with new spacecraft to support data rates up to 100 Gbps.

    Oakville enacts one-year data centre moratorium as Ontario municipalities tighten rules

    Oakville town council approved a one-year moratorium on new data centres on Tuesday, August 12, becoming the first Ontario municipality to formally enact such a pause. The decision follows concerns about noise, vibration, emissions and land-use impacts from facilities powering artificial intelligence. Mississauga is preparing to vote on its own moratorium next month, and other Ontario municipalities including Toronto and Waterloo Region are studying regulatory frameworks for data centre development. The action comes after Hive Digital Technologies announced plans for a 320-megawatt AI facility in the Greater Toronto Area, with land records indicating a Hive subsidiary purchased property in Oakville.

The company completed or contracted over CAD 550 million in acquisitions, including CAD 332 million in wholly owned deals, and announced a significant entry into the UK multi-let industrial market via Chancerygate with CAD 150 million of investment planned.
