The home side have been unstoppable so far in round-robin play and began today's action by brushing aside China 9-4 at the Northlands Coliseum.

They then eased past Germany 8-2 to remain as the only side not to have been beaten so far.

"We are getting a little more comfortable every day," said Canada's second Brett Gallant.

"The key is to bring the intensity for the first half of the game and see where it puts us. 

"If we need to go all ten [ends] we're ready to do it."

Both Switzerland and Sweden are putting pressure on the Canadians, with both countries also winning twice today to move to records of won six, lost one.

The Swiss edged Scotland 6-5 in the opening session before returning to beat The Netherlands, who have lost all seven of their matches, 9-6.

Sweden eased past Italy 8-2 in their first match and then beat Russia, another side yet to get off the mark, 10-5.

Italy, Japan and the United States are the next nearest challengers with four victories and three defeats each.

The US enjoyed a good day with two wins - 9-3 against Norway and then 7-6 over Japan.

Japan preceded their defeat to the Americans by beating the Norwegians 9-7, with Italy bouncing back from their defeat to the Swedes by beating Russia 9-5.

Other matches today saw Germany edge China 6-5 and Scotland beat the Dutch 9-5.

Round-robin play continues tomorrow.
