[3][4][5] In 2007, the ticket office was extensively refurbished, as part of the station upgrade programme delivered through conversion to London Overground.

[6] Between 14 May 1979 and 11 May 1985 the station was served by the Crosstown Linkline diesel multiple unit service between Camden Road and North Woolwich.

The North London line between Gospel Oak and Stratford closed in February 2010, for installing a new signalling system and for extending 30 platforms, in order in due course to allow four-car trains to run on the London Overground network.

This allowed the extended ELL to serve Canonbury (and Highbury & Islington) on a pair of completely segregated tracks occupying the former route on the south side of the cutting.

Since the northern extension of the East London line, which was completed and opened in March 2011, Canonbury station has had four platforms.
