Summary

A trade dispute between Canada and the US has escalated with new Canadian tariffs on $20bn worth of US imports taking effect, targeting sectors such as steel, dairy, and electronics with tariffs ranging from 15% to 50%. This move comes in response to a previous tariff imposed by President Trump on cars and raw materials from Canada. The two countries have been at odds since August when negotiations broke down due to disagreements over trade restrictions and the protection of the French language in Quebec.

Story summary

Here are 6-9 sentences summarizing the real-world news stories:

The Republican Party is holding a midterm convention in Dallas, Texas, which will feature keynote addresses by President Donald Trump and Vice President Pence. This type of event is typically reserved for presidential election years, but Republicans hope it will energize their base ahead of the midterms. The convention will focus on key issues such as border security, economic growth, and American values.

Meanwhile, tensions between the US and Canada are escalating over trade. The Canadian government has announced that it will impose retaliatory tariffs on US goods worth $27.6 billion, in response to the latest round of tariffs imposed by President Trump's administration. This move is expected to have significant economic consequences for both countries, including higher prices for consumers and potential disruptions to supply chains.

In related news, the Canadian government is considering using energy exports as leverage in the trade dispute with the US. However, experts warn that this approach could backfire and harm Canada's domestic oil industry. Some are also questioning whether Prime Minister Mark Carney has the constitutional authority to block or tax Alberta's oil exports to the US.

The US Justice Department has reportedly ordered its antitrust division to pause all work with the Canadian government as trade tensions intensify. However, the DOJ disputes this report and says that no such directive was given. The controversy may be an indication of how far the trade dispute between the two countries has escalated.

Additionally, the economic impact of counter-tariffs is expected to hit not just consumers but also businesses that rely on imported goods, including semi-trailers built in the US that are used to haul goods into and around Canada.
