Ontario skip Rachel Homan replaces lead Lisa Weagle just three weeks after the team's second straight Canadian Championship final loss with Sarah Wilkes coming in as the team's second while Joanne Courtney moves from second to lead.

Wilkes leaves Chelsea Carey's rink which has now dissolved with Weagle now becoming the alternate for Jennifer Jones' incredibly experienced outfit.

Although not in the main quartet for Team Jones, the skip sees more use for Weagle.

"We weren't sure if we were going to add somebody this season or not because we were trying to figure out who that might be, said Jones to the Canadian Press.

"Then Lisa became available and it just filled all the check marks on our list.

"It almost felt too good to be true for us."

One of Canada's best curling skips, Kevin Koe has reunited with his former team-mate and rival John Morris who replaces second Colton Flasch.

Koe last teamed with Morris on the latter's team in the 2005/06 season, with Koe now being the skip as they are on the same rink for the first time in 15 years.

Morris spent many years playing third on Kevin Martin's rink - with Martin widely regarded as Canada's greatest curler.

Recent Junior World champion Tyler Tardi has had a change on his young team replacing Alex Horvath with Jason Ginter.

Another notable set of departures are on Kelsey Rocque's team hailing out of Alberta with lead and second Jesse Iles and Becca Konschuh leaving.
