The men’s Series competition sees the 12 teams divided into three pools of four teams, following the format used at the Olympic Games.
Pool A sees South Africa, who finished as 2020 Series runners-up after reaching the podium in four of the six events, drawn with Series core teams Kenya and Spain and invitational team Mexico.
In Pool B, Great Britain, who narrowly missed out on an Olympic medal after finishing fourth in Tokyo, will face Ireland and invitational teams Hong Kong and Jamaica.
Pool C includes the USA, Series runners-up in 2019, together with hosts Canada and invitational teams Germany and Chile. The hosts will be looking to repeat their performance from the HSBC Canada Sevens 2020 in Vancouver, where they thrilled the home crowd to claim the bronze medal.
The men’s Series event begins with a Pool B encounter between Ireland and Hong Kong at 09:44 PST. The last match of day one promises to be an exciting encounter as hosts Canada take on the USA in Pool C at 18:33 local time.
