The Canadian government has declined to confirm whether it will publicly release the details of a new agreement with the United States governing the Gordie Howe International Bridge, despite growing calls for transparency ahead of the bridge's planned opening.

Prime Minister Mark Carney defended the revised deal, which allows Canada to share a portion of future toll profits with the United States for the next 15 years. The agreement was reached following negotiations with the U.S. administration and is expected to clear the way for the bridge to open on July 27, ending months of uncertainty surrounding the cross-border infrastructure project.

Under the original 2012 agreement, Canada financed the entire C$6.4 billion construction cost and expected to recover its investment through toll revenues over several decades. The revised arrangement changes that plan by directing 50% of net toll profits to an economic development fund benefiting the U.S. side for a 15-year period.

Carney emphasized that the revenue-sharing applies only to net profits, meaning operating costs, maintenance expenses, and debt repayments will be deducted before any profits are divided. He argued that the remaining amount available for sharing is expected to be relatively small and maintained that the agreement serves Canada's long-term interests by ensuring the bridge opens on schedule.

Despite these assurances, the government has stopped short of promising to publish the full text of the agreement. Officials described the arrangement as an agreement in principle, noting that legal and administrative details are still being finalized between Canadian and U.S. authorities.

The lack of public disclosure has drawn criticism from opposition politicians, who argue Canadians deserve greater transparency regarding a project financed entirely with public funds. They have called on the government to release the agreement before the bridge opens, allowing Parliament and the public to fully understand its financial and policy implications.

The Gordie Howe International Bridge is expected to strengthen trade and transportation between Windsor, Ontario, and Detroit, Michigan, making it one of North America's most significant border infrastructure projects. However, debate over the revised financial terms is likely to continue as negotiations are finalised.
