According to KFL&A Public Health, a Class Order was issued to curb the spread of new variants and protect emergency medical services.
The order prevents residents from hosting or attending indoor or outdoor social gatherings with over five people.
It also forces all businesses that serve alcohol to close at 11:00 p.m. and bans dancing, singing and live performances of music.
The temporary restrictions will be in effect from 12:01 a.m. on Saturday, March 13, 2021, to Sunday, March 21, 2021, at 11:59 p.m.
"These measures are prudent and necessary to prevent illness and the spread of COVID-19,” said Dr. Kieran Moore, medical officer of health.
“I want to thank the community for their continued vigilance and support in keeping our community safe," he added.
Anyone caught failing to comply with the new rules could be fined as much as $5,000.
