Led by 2014 Olympic champion Jennifer Jones, Canada recorded a seven-end 11-5 win over the Czech Republic before defeating Switzerland 10-5 in the evening session at the North Bay Memorial Gardens.

"I’ve never had this feeling of playing as Team Canada and it’s wonderful," Canadian alternate Shannon Birchard said after helping her team to victory.

"I never want to take this jacket off.

"I’m going to be soaking up every moment."

The morning session also saw Olympic silver medallists South Korea record an 8-3 win over Germany and China beat Switzerland 6-5.

"After this first game, the whole team is excited and we will play better [in future games]," Chinese skip Yilun Jiang said following her team's win.

"This is my first time as skip, so I’m nervous, but excited.

"As we are a new, young team we will learn a lot form the big games and we will try to experience more."

The final match of the morning session saw Russia record a 8-4 win over Scotland.

Olympic champions Sweden played their first match of the tournament in the evening session, eventually emerging 8-2 winners against Scandinavian neighbours Denmark.

"I think it’s very important for us to focus on the details and just be in the moment, so I think we did that really well in this game," Swedish skip Anna Hasselborg said.

"Of course, there is a challenge coming from a big event to the worlds.

"It helps that we’re in Canada because it’s a dream playing here - it’s just our second worlds."

Elsewhere, the United States thrashed Italy 8-1, while Japan recorded a narrow 6-5 victory over Germany.

The event is due to continue tomorrow.
