The Canadian wildfires started approximately one to two months after the Chinese weather balloon incident.

The Chinese balloon incident occurred between January 28 and February 4, 2023, with the balloon being shot down on February 4th. Canada was impacted by wildfires starting in March 2023, with increased intensity in June. One report states the wildfires started in late April.

In Summary

Chinese balloon incident: January 28 – February 4, 2023.

Canadian wildfires start: March 2023 or late April 2023.

This indicates a time difference of approximately 1-2 months.
