Freeland and Prime Minister Justin Trudeau announced dollar-for-dollar tariffs of their own back in May on some steel and aluminum products and other goods from the USA - including beer kegs, whisky, toilet paper and hair lacques.
The final retaliatory tariff list spells out more than 100 steel products that are being hit with a 25 per cent surtax including bars, rods, and flat-rolled products; 19 aluminum products including doors, nuts and bolts, and scouring pads; and over 70 other US goods that will have a 10 per cent surtax placed on them.
It's all part of Ottawa's plan to strike back at the U.S.in response to hefty tariffs on steel and aluminum, 25 per cent and 10 per cent respectively, imposed last month by Trump.
Numerous US products were chosen for their political rather than economic impact.
"We will not escalate and we will not back down", she added, while urging Washington to reconsider its attack on the Canadian economy, and noting that the response was Ottawa's toughest trade action since World War II.
Trudeau reportedly reiterated his position to Trump himself in a phone call on Friday.
Foreign Affairs Minister Chrystia Freeland unveiled the details - including a finished list of US products on Canada's hit list, which takes effect Sunday - during a news conference at a steel factory in Hamilton.
The Trump administration imposed the steel and aluminum tariffs citing "national security" provisions of United States trade law, drawing a rebuke from allies who have fought alongside American soldiers in multiple wars.
"It is a reciprocal action".
Canada continues to work towards full and permanent removal of these unjustified and illegal US tariffs. "We are perfectly within our rights to respond".
She said she expects "common sense will prevail".
The Trump administration has said the tariffs are necessary to protect the steel and aluminium industries, arguing that their success is vital to America's national security.
Trump himself has already threatened to put tariffs on the automotive sector, which could prove far worse for the Canadian economy than the steel and aluminum duties.

The federal support package is similar to the one offered by Ottawa previous year in response US duties on softwood lumber products from Canada.
But relations between these two neighbors have plunged to their lowest in decades, reaching new depths at the recent Group of Seven summit when Trump abruptly rejected the joint statement and insulted Trudeau.
"I think that prediction has been borne out and I think all of us anticipate there will be some moments of drama in the future".
For companies, Ottawa is promising up to $1.7 billion worth of financing and services for steel and aluminum industries through Business Development Bank of Canada and Export Development Canada.
Major automakers and manufacturers on Friday warned against imposing tariffs in filings with US Commerce Department, which President Donald Trump instructed in May to look into protecting the auto industry.
NAFTA negotiations are expected to move into an "intensive phase" following national elections in Mexico on Sunday.
The Canadian tariffs are created to hit products like steel and bourbon from states like OH and Kentucky that heavily favored Trump in the presidential election.
Bains said the support is aimed at helping firms adjust to the hard circumstances while enabling them to continue to innovate along the way.
Ms Freeland called the idea of auto tariffs "absolutely absurd".
Canada will provide as much as C$2 billion in assistance for affected workers, including plans to expand a work-sharing programme and enhancements to a corporate innovation fund, similar to steps the government took to cushion the impact of a softwood lumber spat. "If you want to change it you have to make serious proposals, but you don't just walk away", he said.
