Lightning - Environment Canada
From Environment Canada, this lightning flash product displays only a portion of the lightning activity in any
given hour.
It shows cloud to ground flashes observed during a 10 minute interval ending at the time shown on the image
(upper right hand corner). Data are updated hourly, with a 2 hour delay.

This map sometimes fails - compare it with the Vaisala lightning map if you ever doubt its validity.
