The province itself only has sufficient resources to fight 40 of the active fires. Fire crews are being called in from New Brunswick and as far away as Mexico and France (!) to help.
That's fairly normal. It's rare to have fires everywhere all at once, so everyone has a low level of resources and shifts it around to assist those who need it. It's not unusual at all to have firefighters from Australia out in Western Canada, and there's fairly regular back-and-forth with Texas as well. It's less common for general firefighting personnel to deploy as far abroad as Australia, but what is common is providing water bombers with experienced pilots and operations crews.
For those not aware, the northern parts of Canada (and even some of the southern parts) are VAST. Not all fires are actively fought, as there isn't enough resources to do that but many of them are simply in difficult to access locations. Based on geography, experience, and some computer modeling, many fires are just left to burn when they aren't expected to cause problems. Others that may pose a threat to cutting off access roads or communities get some attention in the form of fire breaks, back fires (burning out areas so the fire cannot go in that direction), and application of fire ****** (when you see a water bomber dropping orange/red stuff, it's ****** - makes it more difficult to burn rather than trying to douse active flames) but are otherwise just monitored. The ones which, by past events or simple proximity, pose a threat to communities get the lions share of resources to break it down before it gets too big to handle.
edit - site's autocorrect is obfuscating the word for 'fire suppressant material' with asterisks because the text contains 'r-word'. It's the correct term, but comes up so seldom that it's probably not worth putting in an exception.
