Hillstar gained the first top-level victory of his career by winning the Grade One Pattison Canadian International at Woodbine but there was misfortune for the Brown Panther team.
Having looked fractious before the race, Tom Dascombe's Irish St Leger winner dumped Richard Kingscote on the turf and bolted.
Unfortunately for connections, who include ex-footballer Michael Owen, Brown Panther was withdrawn.
Having co-commentated on Manchester City v Tottenham on Saturday, Owen was making the proverbial flying visit to Toronto, with the former England international also set for a stint behind the mic when West Brom take on Manchester United on Monday night.
There were no dramas for Michael Stoute's 6-5 favourite, however, and everything went like clockwork in the race.
Ryan Moore was in the perfect position throughout, as he so often is in these big races, and swung three wide off the bend in a slingshot manoeuvre, shooting clear.
While the American raider Big Blue Kitten closed inside the final furlong, Hillstar had the race won a long way out.
On a remarkable evening for the five-strong team of British raiders at Woodbine, Just The Judge repelled the challenge of compatriot Odeliz in the Grade One EP Taylor Stakes over 10 furlongs.
Charlie Hills’ 8-5 favourite experienced traffic problems in the straight but prevailed by a half-length under Jamie Spencer.
The Nearctic Stakes went the way of David Simcock’s Caspar Netscher as the son of Dutch Art finished strongly for Andrew Mullen in the six-furlong Grade Two contest at odds of 48-10.
