The federal Conservatives have enjoyed a double-digit lead for around a year, but the latest ballot tracking from Nanos Research shows people have been shifting their support to the Liberals after Prime Minister Justin Trudeau announced he's stepping down.

Pollster Nik Nanos and host Michael Stittle look at how Trudeau's resignation, the Liberal leadership race and U.S. President Donald Trump pushing tariffs and threatening the annexation of Canada has forced Conservative Leader Pierre Poilievre to find a new strategy as an inevitable election nears.
