The riding was created in 1966 as "Lakeshore" from part of York—Humber, the same year the 'Lakeshore municipalities', Mimico, New Toronto, Long Branch were annexed to the new Borough of Etobicoke. In 1971, it was renamed "Toronto—Lakeshore". In 1976, it was abolished, and replaced by "Etobicoke—Lakeshore".

The riding was represented by federal Liberal Party and official Opposition leader Michael Ignatieff, who was first elected in 2006, until he was unseated in the 2011 General Election by Conservative Bernard Trottier. Trottier lost to James Maloney of the Liberals in 2015, and Maloney still holds the seat. It was previously represented by Jean Augustine. Provincially, it was represented by Peter Milczyn from 2014 to 2018, and is now represented by Christine Hogarth. On Toronto City Council, the riding is represented by Mark Grimes.

In the 1988 federal election, there was no Liberal candidate on the ballot because two days after nominations were due, the Liberal candidate, Emmanuel Feuerwerker, withdrew citing heart problems after the news media reported that Mr. Feuerwerker's campaign literature claimed university degrees that he did not, in fact, possess.

This riding lost territory to Etobicoke Centre during the 2012 electoral redistribution.
