In a video posted on social media Wednesday, Ontario Premier Doug Ford addressed the ongoing wildfires in the province, pointing out that his government has 156 fire crews and nearly 150 water bombers and helicopters working to extinguish them.
“Our government will not spare a penny to keep people safe,” Ford said, proceeding to tout his government’s investment in forest firefighting, such as adding new personnel and adding new water bombers and helicopters.
He also acknowledged the help the province is getting from Alberta and Yukon. The premier also recognized those who are helping displaced residents.
“I’m encouraged by the compassion and the care we’ve seen from people across the province who are opening their communities to their fellow Ontarians who have been forced to evacuate as a result of these fires,” the premier said.
“I promise that our government will continue to do everything we can to protect people and communities across Ontario.”
The Ontario Liberal Party criticized the Ford government on Wednesday for underspending on emergency forest firefighting. The party said Ontario budgeted only $150 million this year, down from $271 million last year.
“A realistic base budget would allow the ministry to recruit and retain crews, maintain aircraft, secure equipment, and prepare evacuations before communities are threatened, rather than scrambling once fires are burning and families are being forced from their homes,” Ted Hsu, the Ontario Liberal critic for Rural Affairs, Natural Resources, Mining & Forestry, said in a statement.
“The North will come together, as it always does, but its resilience cannot excuse a government that failed to prepare. Protecting Ontario means protecting all of Ontario, with enough crews, equipment and funding in place before the next emergency.”
