Yes, that's definitely a part of it. We've neglected to do controlled spreads of fire to limit these wildfires from being as devastating to the local ecosystems as they are. We're also just getting off a particularly dry spring for the provinces, so that kindling's ready to burn. This of course is accelerated and worsened by climate change. CBC has a whole article about the changing of our wildfires as its impacted by climate change. It's a good read and I'd encourage you to check it out.
