Police said they will be increasing patrols and checks on travellers on the metro, buses and trams.
Masks have been compulsory on all forms of public transport across France since May when the government started to ease its nationwide lockdown.
Masks 'even at family gatherings'
The tougher stance comes as French health chiefs (HCSP) called for the systematic wearing of washable masks. The Haut Conseil de la santé publique said face coverings should be worn in all enclosed public and private spaces.
The HCSP’s declaration emerged after studies revealed that infections were more likely to arise in closed public spaces such as restaurants, buses, boat cruises and choir rehearsals.
On Saturday, Professor Bruno Mégarbane, the head of the intensive care unit at Lariboisière hospital in Paris, echoed the HCSP’s call.
“Masks should be worn even during family gatherings,” he told French broadcaster BFM.
On Saturday morning, the British government's new 14-day quarantine on travellers arriving from France came into effect following the rise in infections.
