Canada, who came into the doubles match with the scores tied at 1-1, have reached the final for the first time.

"We kept fighting," said Shapovalov.

The world number 14 won his singles match against 167th-ranked Safiullin 6-4 5-7 6-4 before world number two Medvedev levelled things with a 6-4 6-0 defeat of Auger-Aliassime, who is ranked 11th.

A Canadian break of serve late in the second set meant the doubles was decided by a tie-breaker in Sydney and Shapovalov and Auger-Aliassime maintained their momentum to claim victory.

Shapovalov added: "Felix played unbelievable in the game to break and then in the tie-break as well, just making them play so much.

"We have great team spirit, so it helped us a lot."

Great Britain were knocked out of the tournament when Canada beat Germany on Thursday.
