Information is your best friend when fires are ongoing or at high risk. You don't want to rely on rumors from a Facebook group. You need real-time data to understand the risk and the current extent of the burns. Here are the tools I use to track fire activity and smoke patterns. 

• FireMap.live: Track all the fires and smoke plumes on one of the best maps I've seen. This resource highlights burn perimeters and active hot spots so you can keep track of what has burned so far and where the current dangers are located.
• FireSmoke Canada: Detailed smoke forecast. Even if the fire is 100 miles away, the smoke can be thick enough to ground planes. Use this to see if you will be breathing clear air or campfire soot.
• Ontario Forest Fire Info: Selectable layers show active fires plus fire danger level and current fire restrictions 
• NASA FIRMS (Fire Information for Resource Management System): This satellite tool shows thermal hotspots in near real-time. This is the way to see active fires and new starts.
• The Outfitter's Satellite Phone: This isn't a website, but it is the most reliable resource. Your outfitter is in constant contact with fire crews. If they tell you it is time to go or time to stay home, trust them. They want you on the water just as much as you want to be there.
