The City of Ottawa had implemented rules with respect to social distancing at outdoor rinks, including Kingsmere Rink. The following info is a rink-specific excerpt from those rules as of Jan. 7 2021:

• Ottawa’s Medical Officer of Health, Dr. Vera Etches, has issued an order under the Health Protection and Promotion Act to restrict the number of people at skating rinks and sledding hills to 25 at one time.
• In addition to the Order, under Provincial Regulations no team sports are permitted and the City is directing that only skating take place on all rinks with no sticks, pucks, balls or other sports equipment permitted on the ice.
• Masks must be worn around all public outdoor rinks and while on the ice and not skating. Masks are not mandatory while skating but are highly recommended. Skaters who are not from the same household must keep two metres apart on and off the ice.
