Conservative Leader Pierre Poilievre is promising to crack down on the use of offshore tax havens and recover as much as $1 billion a year in lost revenues.

In a video posted on X, Poilievre said the money recovered through the initiative would be used to help pay for his plan to introduce a $14-billion income tax cut by reducing the rate in the lowest tax bracket from 15 per cent to 12.75 per cent.
