I can respond to that question.
The original safe return to class fund was a $2-billion fund that was distributed in the last fiscal year to provinces and territories to assist with a safe return to class for students, including ventilation and other measures to improve the health and safety of students and staff at schools.
The $100-million top-up that was proposed in the economic fiscal update is specifically targeted to ventilation measures. It will be provided to provinces and territories to fund things like the repair and replacement of heat, ventilation and air conditioning units, increased maintenance of existing systems to ensure optimized operation and other interventions that would bring in more outdoor air or result in cleaner air, such as the installation of operable windows or portable air filtration units.
