Hours after a bomb threat prompted Nunavut’s Department of Education to evacuate and close schools across the territory, police have deemed the threat a hoax.

According to Nunavut RCMP, all elementary schools, high schools and colleges in the territory have been checked by school staff and officers, leading them to declare the threat “not credible.”

Nunavut RCMP received a threat at 9 a.m. Thursday, saying that bombs had been left in schools across the territory.

“If you are the parent or guardian of a child in a school or daycare in a school, please pick them up immediately,” Nunavut’s education department said in a public service announcement posted online after the threat was made public. “The RCMP is responding to this threat by conducting thorough walk-throughs of all schools, and school property and facilities.”

The threat in Nunavut comes a day after the evacuation of nearly 20,000 students in Prince Edward Island on Wednesday, after the RCMP were faxed a bomb threat that was also later deemed a hoax. Similar threats were also made against schools in Winnipeg, Newfoundland and Nova Scotia on Wednesday, leading to some evacuations. No bombs were found.

Nunavut RCMP says that it is working with other agencies across the country to identify whomever is behind the string of threats.

Even before the all-clear, some Nunavut residents on social media were quick to dismiss the threat as a hoax.

So Arctic Bay school is closed as well. Like some idiot with a fax machine is going to drop $7K to fly there, blend in, and plant a bomb. — Clare Kines (@NunavutBirder) September 22, 2016

Others commended the RCMP and school officials for their swift response.
