A 12-year-old asthmatic Canadian boy died after being unable to use his inhaler at a school which has a policy of confiscating them.
Sandra Gibbons has spent the past year lobbying to have Canadian policies on inhalers changed to allow students to carry them.
Mrs Gibbons says Ryan's school's policy on inhalers claimed his life.
She said his friends had to carry him to the principal's office to get his inhaler because the school has a policy banning students from carrying them.
"So as he was going to the office to get his inhaler, he kind of was having a hard time and had to be carried into the office, and by the time he got there he had blacked out," Mrs Gibbons told the Canadian Press.
"To this day I really don't know how exactly the whole day unfolded for him," Mrs Gibbons said.
She said inhalers were regularly confiscated at the school.
CTV News reports that policies on asthma inhalers are not uniform across Canada.
In some schools, students are not allowed to have them outside of the principal's office, some have medical stations where teachers have pictures of students who need inhalers but still don't have it on hand, and in other schools it has to be in the teacher's desk.
In other schools, students can carry their inhalers provided they have written permission from a parent or guardian.
Mrs Gibbons says that she regularly received calls from Ryan's school to say he had been caught carrying his inhaler.
"He wasn't even allowed to bring it home with him," she said.
