Former Prime Minister Stephen Harper issued a stark warning at an Ottawa gala, urging Canada to reduce its reliance on the U.S. to safeguard its sovereignty and economic stability. Harper's call comes as a response to the erratic behavior of the U.S. president, who has openly questioned Canadian sovereignty and undermined trade agreements. He emphasizes the need for a balanced and sober approach to the Canada-U.S. relationship, suggesting the implementation of tariffs on U.S. goods to protect Canada's industrial base and critical resources. Harper's stance contrasts with his previous pro-American stance and highlights the growing tensions between the two nations. The article also mentions the potential impact on the natural resources sector and the need for Canada to adapt to new geopolitical realities.
