The province is announcing a new mask mandate and reminding residents of another that takes effect Tuesday.
Students taking the bus in Manitoba are now required to wear a mask.
"As students prepare to return to school, masks will be required on all school buses as passengers may be in close proximity for extended periods of time with no ability to physically distance from each other," the province says in a statement.
Previously, only students in Grade Four and higher required. Now all students, drivers, and other passengers are required to wear a mask.
In the City of Winnipeg, masks are mandatory for those on public transit as of September 5.
The province is reminding residents that starting Tuesday, masks are required to be worn at health-care facilities.
"While primary care clinics and other locations providing health services are not currently included in the mask requirement, all Manitobans are strongly encouraged to wear a non-medical mask when seeking care," the province says.
The health-care facility mask requirement includes outpatients attending appointments at clinics within hospitals and health centres in Manitoba.
