Canadian athletes turned up the heat at the Beijing Olympics Tuesday pushing Canada's medal count to 13 -- more than the 12 won at the 2004 Games.

Triathlete Simon Whitfield, gymnast Jason Burnett, and diver Alexandre Despatie all took silver while hurdler Priscilla Lopes-Schliep pulled off a bronze medal performance.

The day began with Whitfield securing his silver medal with a time of one hour 48 minutes 53 seconds -- just five seconds behind Germany's Jan Frodeno.

The 33-year-old won gold in the triathlon event at the 2000 Sydney Olympics but did not qualify for a medal at the 2004 Athens Olympics.

"To be able to fight my way back to the podium, that was hard, that was so hard -- this was a harder race than Sydney was," Whitfield said.

Meanwhile, Burnett was ecstatic after garnering a medal in his first Olympic performance.

He finished second with 40.7 points after completing a stunning routine that had the highest degree of difficulty in the competition.

"I just felt like I was in the zone out there today, everything went the way I wanted it to," said Burnett.

Burnett said he was inspired after watching Karen Cockburn win a silver medal on Monday in women's trampoline.

Burnett's coach, Dave Ross, said he was impressed by the 21-year-old's performance.

"I think the home crowd advantage gave the Chinese gold medal winner a bit of a boost and that was enough to bump Jason down into second place, but to me he did the best routine today," said Ross.

The final silver medal went to Despatie in men's three-metre springboard.

Despatie scored 536.65 to earn his second Olympic silver medal -- the first won at the 2004 Games.

In first place was China's He Chong with a dominating score of 572.90.

Last April, Despatie fractured his right foot playing soccer, forcing him to miss nearly two months of training and the Olympic diving trials.

To make the Olympic team, Despatie had to dive before a panel of judges to prove his fitness.

"I still can't believe it! This silver medal is worth gold for me, especially with the year I had," said Despatie.

On the track, Lopes-Schliep captured bronze in the women's 100-metre hurdles with a time of 12.64 seconds.

The 25-year-old Whitby, Ont., native raced in front of a capacity crowd at the 91,000-seat Bird's Nest stadium.

Her win is the first track medal for Canada since the 1996 Olympics in Atlanta where Donovan Bailey won gold in the 100 metres.

The medal was originally favoured for Perdita Felicien but she had to bow out of the Olympics after suffering a stress fracture in her foot.

Including Tuesday's medals, Canada now has two gold, six silver and five bronze medals.
