The 30-year-old from Oakville, Ont., won his morning heat and semifinal under sunshine at Eton Dorney. Van Koeverden, the current world champion, won his semi in three minutes 28.209 seconds.
The final goes Wednesday.
Mark Oldershaw of Burlington, Ont., also reached the C-1 1,000-metre canoe final, placing second in his semifinal.
Van Koeverden already has a gold, silver and bronze from the Olympics. He won gold and bronze, in the K-1 500 metres and K-1 1,000 metres, in Athens, and a silver in the K-1,000 in Beijing where he also finished eighth in the K-1 1,000.
The 500-metre race has been replaced with a 200-metre sprint in these Olympics, so van Koeverden is just racing in the 1,000.
Van Koeverden, dominated the opening heat of the day and led by four seconds at the 750-metre mark before easing off the throttle and finishing in 3:28.697. It was the fastest time of the three heats.
Training partner Anders Gustafsson of Sweden (3:34.419) and Denmark's Rene Poulsen (3:30.284) won the other heats.
