Canadian AI Safety Institute — Headquarters: Ottawa, Canada

Note: While the source URL is from ised-isde.canada.ca and the source text confirms CAISI is led by ISED (which is based in Ottawa), the source text itself does not explicitly state that CAISI's headquarters is in Ottawa, Canada. The claim requires a direct statement about the physical location of the headquarters, which is not provided in the excerpt. The URL domain and organizational structure suggest Ottawa as likely, but this is not explicitly confirmed in the source text.

Note: While the source confirms that CAISI is under ISED (Innovation, Science and Economic Development Canada) and provides the URL from the ISED domain (ised-isde.canada.ca), it does not explicitly mention Ottawa, Canada as the headquarters location. The source discusses the institute's mission, work, and partnerships but omits the specific geographic headquarters information needed to verify the claim.
