BC Place and Vancouver Lookout were among the five landmarks in Vancouver which counted towards the RCAF’s successful Guinness World Record attempt for number of landmarks illuminated in 24 hours.

Making the cut

According to the Department of National Defence (DND), the RCAF needed to follow strict guidelines provided by the Guinness World Records to make the cut.

To be considered a landmark by Guinness World Records, a location had to be recognized by UNESCO, national governmental registers, or significant third-party registers.

To enter into the records, the RCAF needed to include evidence such as a ten-minute timestamped video, a photo of the landmarks and two witness statements, shared DND.

The CN Tower in Toronto illuminated in blue on April 1st, 2024, for the Royal Canadian Air Force (RCAF) Centennial Illumination campaign. The iconic Canadian landmark was one of the 56 landmarks which counted towards the RCAF’s successful world record attempt.

To celebrate achieving this milestone, the official Guinness World Records certificate was presented to the RCAF commander. It was also presented to Chief Warrant Officer John Hall, Command Chief Warrant Officer of the RCAF, and Captain Aaron Niles, Strategic Planner for the RCAF Centennial Team and lead for the illumination campaign, during the RCAF Centennial Ball on June 1, 2024, in Ottawa.
