Canada has clinched a major 14-12 upset victory over Australia thanks to a conversion after the full-time siren at the Canada Sevens event in Vancouver.  
Leading 12-7 with 23 seconds remaining, Australia's Lewis Holland failed to execute a regulation line-out which resulted in Canada having one last throw of the dice. 
After pushing forward to within striking distance, Canada's Adam Zaruba made the most of James Stannard's sin-binning by crossing to equal the scores, before Nathan Hirayama's successful conversion sent the home crowd into hysterics. 
Australia need to win their final match of the day against Wales at 2.06pm to be any chance of winning the tournament. 
Hirayama and Thunderbolts speedster Allan Fa'alava'au scored the only two tries of the first half which saw teams go into the main break at 7-7. 
Tom Kingston put Australia up 12-7 with four minutes to go before Quade Cooper was subbed on. He only touched the ball a handful of times and was unable to make a major impact. 
After two finals in Sydney and Las Vegas, the loss will come as a shock to the side who are without rested captain Ed Jenkins and try-scoring machine Cam Clark. 
Coach Andy Friend will be hoping his team can employ the same ruthless mindset they showed against Russia in which they crushed 43-5 earlier in the day.
