From a climate change perspective, we've now seen several years of extreme wildfire activity across the country. We know that last year in particular, northern Alberta, the Northwest Territories and northern Quebec were significantly impacted by wildfires.
Servicing all of Nunavik and the Eeyou Istchee area of Quebec was impaired when the Billy Diamond Highway was closed intermittently over a one-month period, impacting the delivery of food for all residents of northern Quebec and Nunavik and the Eeyou Istchee, who were at significant risk. We worked diligently to redesign our supply network through northern Ontario, and we were then flying goods across the bay to service those communities instead of through La Grande-Rivière airport.
In northern Alberta, we lost a store to wildfire. It was small in comparison to the tragedy of the entire community. I believe there were over 80 homes burned in Fox Lake, Alberta, and there was significant disruption.
The city of Yellowknife was evacuated.
We've seen low water conditions on the Mackenzie River that have caused the cancellation of barges.
We've seen the erosion of foundations in some of our stores, and we are having to now invest millions of dollars in infrastructure because of melting permafrost. We've seen soft runways in places in northern Manitoba that have restricted the size of the aircraft that are able to land.
All of these things drive costs into the business and create hardship for our northern and remote communities and the folks who live there.
