Darcee Gosselin was dedicated.

Her parents said the John Taylor High School teacher always went the extra mile, even staying after school to help her students.

"She was just one of those teachers you'd like your kid to have," said Darcee’s mom Vicki Gosselin.

It was no surprise to Vicki and Perry Gosselin that their 40-year-old daughter wanted to go on a field trip in May 2016 to the Spirit Sands desert near Carberry, Man. despite having reservations.

"She didn't like the heat and I talked to her the night before and I said well don't go," said Vicki Gosselin.

During the trip with grade eleven and twelve students, Darcee Gosselin collapsed. She was taken to the hospital in Carberry. When her parents arrived that night, RCMP delivered grim news: their daughter had died.

"It didn't seem real, you don't want anybody to go through that who has children to ever have to go through that, and I know people do all the time but it was terrible we were in shock," said Perry Gosselin.

The initial diagnosis was a heart attack, but days later the medical examiner called with a very different conclusion.

"She was upset and she said I'm very sorry it was heat stroke and it was preventable," said Vicki Gosselin.

The couple is speaking out, urging the education minister and all school divisions to change the policy for field trips, especially when it comes to extreme heat.

In a statement on behalf of Education Minister Ian Wishart, the province said a resource manual is already available for divisions on how to reduce risks on field trips.

"It covers risk assessment considerations for outdoor pursuits, including body temperature control, and the importance of preventing, recognizing and treating heat stroke and heat exhaustion."

The Gosselin's said Darcee was wearing a hat and had water. They said the current policy didn't protect their daughter, it was 40 degrees that day, and students and staff were still allowed to roam.

"She shouldn’t have been out there, none of them, none of those kids should have been out there in that heat," said Vicki Gosselin.

The Gosselin’s are meeting with a lawyer over this matter.

The St. James Assiniboia School Division did not want to comment sending CTV News the following statement:

“The division respectfully declines to comment further regarding this tragic situation.”
