Tottenham’s opener came in the fifth minute thanks to some sharp play from Lewis Holtby.
The 23-year-old midfielder reacted quickly after Fire goalkeeper Sean Johnson played an ill-advised pass to Jeff Larentowicz, nicking the ball off the former Colorado Rapids’ player before squaring the ball for Kane to tap into an empty net.
Johnson slightly atoned for his mistake with two fines first-half saves to deny Erik Lamela, the first low to his left, the second a full-length stop after the Fire defence had allowed the Argentine midfielder to cut in from the right channel.
The second half was scarred by a raft of changes, and Chicago Fire, who are in the middle of their domestic season, replaced their whole starting eleven.
Lennon wrapped up the victory with seven minutes remaining, showing great bravery to beat Bakary Soumare to Roberto Soldado's chip over the top, then cutting across the area before rolling the ball past Fire's second-half goalkeeper Kyle Reynish.

‘5 GOAL!! Harry Kane nets from close range after Lewis Holtby robs Jeff Larentowicz following a poor pass from Fire goalkeeper Sean Johnson.
‘24 GOOD SAVE. Walker commits a foul down the right and Fire win a free-kick. The ball rolls to Matt Watson, who forces Friedel into a full-length block.
'29 GOOD SAVE. Lamela skips past a couple of defenders and shoots across goal but Johnson makes a good stop low to his left.
‘33 GOOD SAVE. Lamela drives towards goal after cutting in from the right, and no Fire defender comes to him, but Johnson makes another good save, this time to his right.
‘67 SAVE Duka gives and goes and shoots from the edge of the box but Friedel is down to save.
‘83 GOAL!! Lennon is brave to beat Bakary Soumare to Soldado's chip over the top, and the England winger cuts across the area before rolling the ball past Reynish.
‘85 SAVE. Fire are again undone by the chipped ball over the top but Reynish is out quickly to deny Eriksen.
TALKING POINT: How do you solve a problem like Lamela?
The Argentine scored twice against Toronto and sparkled at times against Chicago Fire, but the £30m signing from Roma is wasteful with the ball and often gives away possession needlessly. The 22-year-old really needs to show more discipline and game sense if he is to be a regular in the Premier League next season.
