Caldwell took charge with a sparkling second turn and finished in two minutes 9.31 seconds to take the world team spot in the event. Genevieve Cantin of Ste-Foy, Que., was second in 2:11.45 and Canadian record-holder Sinead Russell of Burlington, Ont., was third (2:11.52).
"I felt a lot of pressure tonight to get on the team," said Caldwell after her first career national win. "I was hoping to get this done in the 100 backstroke (on Wednesday). I’m excited to be going to the worlds and my goal there is to do a lot better than at the Olympics."
Caldwell and double Olympic medallist Ryan Cochrane of Victoria were among five new names added to Team Canada for the FINA World Championships July 19 to Aug. 4 in Barcelona. The total is now 29 team members with one day of competition remaining at Saanich Commonwealth Place.
Cochrane cruised to an easy win in the men’s 400-metre freestyle in 3:47.08.
"I was hoping to go faster but it’s a super-encouraging time," said Cochrane, whose time was the fourth fastest in the world this year.
Two young Canadians qualified for the national team in the women’s 100-metre butterfly.
Katerine Savard of Quebec City was the victor in 58.06 and Noemie Thomas of Vancouver followed in 58.31. Savard also made the cut in the 200-metre butterfly on Wednesday.
Savannah King of Vancouver also qualified for a second event winning the women’s 400-metre freestyle.
On the men’s side, Russell Wood of Calgary and Coleman Allen of Vancouver added their names to the national squad with victories in the 200-metre backstroke and 100-metre butterfly.
Competition continues Saturday at Saanich Commonwealth Place.
