A northern Alberta community that’s no stranger to the devastation of a wildfire is on standby to flee if needed. After lightning from a thunderstorm sparked a fire on Sunday in the Municipal District of Lesser Slave River, an evacuation alert was issued both for the rural area surrounding the blaze, as well as for the town of Slave Lake — which was razed by one of Alberta’s costliest wildfires in 2011. At the time, nearly 400 homes and businesses, including an apartment complex and town hall, were reduced to ash and rubble when fierce winds whipped flames through the town north of Edmonton with little warning. Damages were pegged at $700 million …In the nearly 15 years since the Slave Lake wildfire, the community has made changes from lessons observed at home and elsewhere. One such change: modifying fire trucks so they can be more responsive to wildfires, not just structure fires in town.
