The reports are that the Canada wildfires started in late April. I checked lightning strike maps at https://www.blitzortung.org/en/historical_maps.php

I looked at all April days, and early May. Although there were some strikes recorded in eastern Canada on a couple days, they CERTAINLY can't account for most of the fires. I think the deep state feels they can do anything and that it doesn't matter if they are obvious, because their "fires caused by lightning strikes" is EASILY disproven!
