The riding was previously considered one of the safest Liberal Party seats in Canada; however, this changed as the Conservative Party gained ground in the 2000s, and its candidate Mark Adler won the seat in 2011. However, the Liberal Party regained the seat in 2015 with its candidate Michael Levitt. Levitt was re-elected in 2019, and resigned as of September 1, 2020, to become the CEO of the Friends of Simon Wiesenthal Center for Holocaust Studies. A by-election to fill the vacancy took place on October 26, 2020, which was won by Liberal Ya'ara Saks.
