Canada is putting tariffs on more than $12bn worth of American goods. They will come into effect on Sunday and will target not just US steel and aluminium but also consumer goods like orange juice, whisky and even toilet paper. We hear from our economics correspondent Andrew Walker and whisky producer Colin Spoelman from Kings County distillery in Brooklyn.

President Trump has communicated much of his economic policy on Twitter; as part of the 主播大秀's Money and Power series we hear from Dr Stephanie Hare who researches technological trends.

We round up the week's biggest news stories with Katie Martin from the Financial Times and Richard Cockett from The Economist.

And we're joined throughout the programme by Cathy Alexander, research fellow at the Melbourne Sustainable Society Institute.
