Joshua Tree will be considered for the Breeders' Cup Turf at Churchill Downs next month after running a fine race in Sunday's Canadian International.
The Marco Botti-trained colt had finished third behind brilliant Arc winner Danedream in Germany on his penultimate start, and confirmed that promise by chasing home John Hammond's Sarah Lynx at Woodbine.
He had Aidan O'Brien's Treasure Beach and fellow British raiders Arctic Cosmos, Quest For Peace and Redwood behind, and could head back across the Atlantic if Botti is pleased with his training in the meantime.
"He ran a very good race and we were all very pleased," said Botti.
"The French filly showed a very good turn of foot and was very impressive. Our horse was a bit slow from the stalls, but he finished nicely.
"We expected him to run well, but you never know until the day.
"I have spoken to the owners and we will have a think about the Breeders' Cup Turf if he trains well over the next few weeks.
"He has to come back to England first and then start training again, so it could possibly come too soon.
"But he is still quite a fresh horse and we will see how he goes when he comes home and then make a decision."
