Note that the news item cited above refers to municipal fire bans. Algonquin Park is still included in a wide area that is under a total fire ban imposed by the MNRF, which supersedes any municipal ban. Regardless of rain or other changes in conditions in the near future, it may be a while till the MNRF ban is lifted, due to the demands of currently active fires on available firefighting resources. There simple aren't enough people or equipment to handle anything more at the present time.
For example, the fire designated Pembroke 6, covering 697 hectares (a little over 1700 acres) is currently burning out of control about 20 miles from where we live. The crews dealing with it include 20 firefighters from Mexico. There are also personnel from Mexico working on the big Parry Sound fire, and other crews have come to Ontario from B.C, Alberta, Saskatchewan and Nova Scotia to assist.
Fortunately, there is only one fire burning within the boundaries of Algonquin Park (south of Stratton Lake) at the moment. We should all make every effort not to add to the total.
