[8][9] In 2010, the city began preparation work, including utility relocations, building removals, roadwork, Kingsway road reconstruction and track slab construction.

[10] The public plaza surrounding MacEwan station, except for the area required to build Rogers Place, opened for use by people other than the construction crew in December 2014.

[15] On August 30, 2021 (late evenings and Sundays starting June 27[16]), service on the Metro Line was modified to end at Health Sciences/Jubilee station, as was originally planned but delayed due to signalling issues which caused trains to run a reduced frequency to the interim terminus at Century Park station, to ensure the Capital Line could run at full frequency.

[17] In June 2020, construction began on phase one of the Metro Line northwest extension, which consisted of two stops: NAIT/Blatchford Market, which replaced the temporary NAIT station in use for eight years, and Blatchford Gate.

[24][25][26] Thales gave control of the system to the City of Edmonton in March 2015, but failed to provide adequate documentation to place the line into service.

In April 2019, the City of Edmonton terminated its contract with Thales, and sought other options to complete the line and bring it up to full service.

[13] The extension would have eight stations, including stops in Blatchford, Rosslyn, Griesbach, Castle Downs, The Palisades, and at Campbell Road.

[35] Phase one, consisting of two stops: NAIT/Blatchford Market and Blatchford Gate, began construction in June 2020 and was completed in December 2023 with the latter station remaining non-operational until the criteria for the city’s transit service standard is met.

[37] On November 12, 2013, St. Albert council decided to continue studying LRT alignment options, but not to put any money into purchasing land or rail cars.

The line is proposed to be primarily aligned to the east of St. Albert Trail, reducing it to four lanes north of Hébert Road.

As well, there are three new bridges proposed along the St. Albert extension to span Anthony Henday Drive, Sir Winston Churchill Avenue, and the Sturgeon River.
