Calgary's Robert Thirsk High School will be open again on Tuesday after extreme cold caused flooding.
The northwest school had to be closed after a radiator burst. That led to flooding, which caused extensive damage on three floors of the school.
"The school will be ready to reopen to students on Tuesday though some classrooms will remain closed while the clean-up continues," school board officials said in a press release.
All other CBE schools remained open Monday.
The cold also meant delays for some school buses Monday morning.
Officials with busing companies Southland and First Student Canada said they worked throughout the weekend to keep their mainly diesel-fueled buses from freezing.
But Mike Stiles with First Student Canada said Monday morning the frigid cold was already causing delays.
“We have a few no-starts this morning already. We did have measures in place and early this morning to minimize delays. Right now we're looking at anywhere from a 20 to 30 minute delay on a few routes ... I'm going to say ten routes,” he said.
The Calgary Board of Education (CBE) is warning parents not to leave children alone at bus stops in the extreme cold.
Officials are also recommending parents provide alternate arrangements for their children so they can get out of the cold, such as a neighbour who will be at home during the day.
