OTTAWA - Systematic government collection and analysis of data about mysterious sightings in the sky could help Canada better prepare for incidents like the sudden appearance of several high-altitude balloons over North America two years ago, says a report from the federal science adviser.

One of the balloons, which wafted above Western Canada in early 2023 before being shot down off the U.S. coast, apparently originated from China and carried sophisticated equipment.
