A fortnight after a big political setback to the ruling Justin Trudeau-led Liberal government with New Democratic Party (NDP) leader and Indian-origin politician Jagmeet Singh withdrawing support, another major blow came the prime minister's way as his party lost Montreal’s LaSalle-Émard-Verdun seat in Quebec – a Liberal stronghold – to the Bloc Quebecois Party in a byelection held on Monday, 16 September.
On the other hand, Winnipeg’s Elmwood-Transcona seat in the Manitoba province was retained by the NDP.
With Trudeau's declining approval ratings, the byelections were a litmus test for him as well as other Canadian leaders. The timing of the polls, soon after Singh's decision to withdraw support alleging that the Canadian prime minister was not "delivering" on his promises, had made the contests even more interesting.
