Ryan Cochrane today added the 1,500m freestyle gold to his 400m freestyle win to give Canada its second double gold of the day at the Commonwealth Games.
The 21-year-old swam in front virtually the whole way and finished in 15:01.49. The leading chaser, South Africa's Heerden Herman, won silver, with England's Daniel Fogg winning the battle of the rest for bronze.
The event has been dominated over the years by Australia and Cochrane, the Olympic bronze medallist, was well outside Kieren Perkins' Games best of 14:41.66 and Grant Hackett's world record time of 14:34.56.
Cochrane's gold comes after he won the Pan Pacific Championships in August.
Defending Commonwealth champion David Davies of Wales finished down the field despite being on the early pace.
Canada's Brent Hayden earlier added the 50m freestyle to the 100m freestyle title.
