Bouchard struck the ball early and with searing power to dominate the first set, but squandered game points on all but one of Konta's service games in the second as the match turned in favour of the British player.
Konta had a break point at the start of the deciding set but Bouchard saved it with a volley and two double faults in the next game allowed her to move into a 2-0 lead.
The writing was on the wall for Konta when Bouchard battled back from 0-40 to hold for 3-0.
Konta did stop the rot at 0-5 but Bouchard was too far ahead and sealed victory when Konta wafted a return long.
Only one British woman is left in the draw with Tara Moore playing Svetlana Kuznetsova in the second round on Friday.
