Roberto Mancini's side edge further clear at the top of the table thanks to a resounding win over the Canaries at the Etihad stadium
Roberto Mancini's side were dominant from the off, with Sergio Aguero, Mario Balotelli and Samir Nasri among the scorers, and move seven points clear for the time being, with rivals Manchester United featuring at Aston Villa later on Saturday.
Mancini decided to line up with Aguero and Edin Dzeko up front, while Balotelli started from the bench after serving a suspension in midweek.
Steve Morison was playing in an isolated lone role up front for Norwich but still managed to cause Kolo Toure problems on a rare Premier League for the Ivorian.
First Toure dithered with a bouncing ball and Morison latched onto it, hitting an effort from 40 yards which sent Joe Hart scrambling to his right, before a mix-up between both City centre-backs saw Morison through on Joe Hart's goal, but a heavy touch from the striker let England's No. 1 shut off the opportunity.
The game then swiftly became one-way action with City trying to pick holes in Norwich's side as they kept 10 men behind the ball at all times, the creative trio of Aguero, David Silva and Nasri sharing the creative duties.
Dzeko had an effort blocked and the afternoon was threatening to become a frustrating one for City until they finally found a way through the wall of yellow shirts.
Nasri played the effervescent Micah Richards in down the right channel who played the ball into the box to Aguero and, when faced with five Norwich players, turned into space and toe-poked the ball through the crowd and into the Norwich goal.
City were not happy to sit back on their goal; Toure powered through midfield and played Nasri in down the right who again found Aguero at the back post but the Argentine fired his effort over and could have easily had a first-half hat-trick.
Norwich managed to hold out until half-time and had a great chance to equalise in the second minute of the second half, when Kompany missed his header and Elliot Bennett found himself through on goal.
The former Brighton winger rounded Joe Hart but the angle became too narrow and Bennett could only fire wide.
City then extended their lead minutes later. A free-kick was played in by Nasri, and the ball ending up in the back of the net after evading Norwich defenders and City attackers.
The home side were now fully into their attacking groove, Silva jinked into the box and hit a rasping effort towards John Ruddy's near post which was saved but fell to Aguero following up but he was denied brilliantly by the custodian.
A change was needed for Norwich and Paul Lambert decided to take the game to the hosts, bringing on Grant Holt and Wes Hoolahan for Anthony Pilkington and Elliott Bennett, forcing a change of formation and perhaps style.
The change failed to have the desired effect however as another City short corner was worked by Aguero and Nasri into Yaya Toure, who curled a sumptuous shot into the corner from 15 yards.
Mancini wasn't looking happy with just three, sending on Adam Johnson for Samir Nasri and one of the loudest cheers of the afternoon greeted Mario Balotelli as he replaced Aguero.
Norwich were still working hard however and were finally rewarded for their efforts, Surman's drifted cross was met by Morison, the Welshman powering a bullet header past Joe Hart.
City regained their three goal cushion through substitute Balotelli, played in by Johnson the Italian's initial shot was blocked into the air and as it fell the enigmatic forward hit the ball into the net with his shoulder.
And the Citizens extended their lead further in injury time, Vincent Kompany picking the ball up and finding Adam Johnson who slotted home from the right hand corner of the box.
