The Ministry of Environment, Conservation and Parks says it decided to shutter the parks until April 30 to protect the health of employees and visitors.
Andrew Buttigieg, a spokesman for the parks minister, says staff will post signs at park entrances to notify people about the closures.
He says where possible, park entrances will be gated and buildings locked.
Buttigieg says ministry staff will get in touch people who are in the backcountry or at campgrounds to tell them about the closure.
They’re being asked to leave by Thursday.
