TORONTO – The moment he touched the wall Jonathan Dieleman thought of his grandfather.

The Para-swimmer from Quick, B.C., lowered his own Canadian record in the S3 50-metre breaststroke during Wednesday morning’s heats at the Olympic & Para-swimming trials, presented by RBC. Dieleman dedicated the race to his recently deceased grandfather Henry Klock.

“Being able to do this time was something I was really hoping for, just to get some good memories of my grandfather,” said Dieleman.

“Being able to do this time was something I was really hoping for, just to get some good memories of my grandfather,” –  Jonathan Dieleman.

Also setting Canadian records during the morning session was Kylie Masse of Lasalle, Ont., in the women’s 100-m backstroke and Para-swimmer Tammy Cunnington in the women’s S3 50-m.

Masse’s time of 59.17 seconds broke the old mark of 59.68 set by Sinead Russell in July 2011.

“It’s so exciting to see all the hard work pay off,” said Masse. “I’ve done a lot of minor things throughout the season since last summer. I’m happy with how I executed.

“Hopefully I can repeat tonight.”

Masse needs to finish first or second in tonight’s final, and swim under the Olympic qualifying time of one minute, 0.25 seconds to be nominated for the Games’ team.

The trials, which end Sunday, have attracted 762 swimmers from 187 clubs cross Canada, the United States and other parts of the world. The competition is being held at the Toronto Pan Am Sports Centre, the same pool which hosted last year’s Pan American and Parapan Am Games.

All finals sessions will be webcast live on CBCSports.ca beginning at 6:45 p.m. ET. For full results and more information visit www.swimming.ca/trials.

Due to the nature of the selection criteria for the Para-swimming team, all nominations will be announced after finals on Sunday.

Dieleman, who was left a T4 paraplegic after a dirk biking accident, won his race in 50.39 seconds, knocking 2.70 seconds off the record he set in January. He believes there’s room for improvement in the evening final.

“I felt like I have quite a bit yet,” he said.

Cunnington of Red Deer, Alta., swam her race in one minute, 16.44 seconds. She sliced over four seconds off the old mark set by Kirston Harwood at the 1996 trials.

“I wanted to break the record,” said Cunnington. “I didn’t expect to break it by that much.”

Nicolaas Dekker of Richmond, B.C., was the top Canadian in the men’s 200-m butterfly with a time of 1:59.35 while Coleman Allen of Vancouver was just .04 behind. The Olympic qualifying time is 1:56.97
