The hot weather has the Ministry of Natural Resources on high alert for new forest fires this long weekend. The Thunder Bay Professional Fire Fighters Association is also asking you to "use caution" if you intend to use fireworks. President Eric Nordlund is reminding you that it is illegal to set them off within city limits. Nordlund is suggesting you watch the fireworks display put on by the city at Marina Park on Canada Day at approximately 11:00 O'clock.
