Canada slapped the US with tariffs on over 12 billion dollars worth of goods Sunday,

as the country celebrates Canada Day.

It's in retaliation for US tariffs placed on Canadian steel and aluminum.

Canada imposed taxes of up to 25 % on US goods, including whiskey, yogurt and ketchup.

A Canadian news outlet named Heinz ketchup as one of the top items to avoid

in case of a US - Canada trade war.

After Heinz shut down a factory in Ontario in 2014,

French's, known in the US for its mustard, became an alternative ketchup - maker in Canada.

In a symbolic move, Canadian Prime Minister Justin Trudeau is visiting the former Heinz plant

on Sunday to meet with working-class employees.

Canada 's foreign minister called the tariffs regrettable, but said they're a perfectly reciprocal action.

It's a dollar for dollar response.

Taxed goods were selected to put financial pressure on states with high-profile Republican leaders.

Most of Canada 's imported yogurt comes from house speaker Paul Ryan 's home state of Wisconsin.

Mexico employed the same tactic early last month, when it - among other items - taxed whiskey.

Senate majority leader Mitch McConnell 's home state of Kentucky is a major producer of whiskey.
