Deloitte Canada cuts 2027 GDP growth forecast to 1.6% due to US tariffs
Deloitte Canada cut its 2027 gross domestic product growth forecast to 1.6% from a previous 2% projection, citing a sharp economic slowdown driven by a new round of U.S. tariffs and import bans taking effect September 29.
Revised Growth Projections Reflect Mounting Trade Pressures
Accounting firm Deloitte released its updated economic outlook on September 29, warning that aggressive trade policies from Washington will significantly hamper economic momentum late into the year and heading into 2027. While the firm raised its 2026 growth estimate slightly to 0.9% from an earlier 0.7% forecast, the longer-term outlook reflects deteriorating conditions.
Dawn Desjardins, an economist at Deloitte Canada, described the changing environment for domestic enterprises. According to Desjardins, the pressure from billions of dollars in American tariffs and reciprocal Canadian measures will create an uneven recovery across the country.

Uneven Sector Impact and Federal Intervention
The economic turbulence does not affect all industries equally. While export-oriented manufacturing and material sectors face intense margin compression under heavy levies, targeted government support aims to stabilize vital domestic supply chains. Federal funding initiatives, infrastructure investment, and defense spending provide localized buffers for specific labor markets, though the overarching business climate remains highly volatile.
Prime Minister Mark Carney’s administration rolled out financial support packages totaling billions of dollars to assist affected workers and corporations.
Stagnant July Output Precedes Tariff Implementation
Statistics Canada reported on September 29, that the nation’s real gross domestic product remained completely flat in July, following a period of moderate expansion in the second quarter. Goods-producing industries showed virtually no net change as gains in construction and utilities offset declines elsewhere. Service industries likewise held steady, as retail and wholesale trade pullbacks countered gains in other segments.

Andrew Grantham, an economist at the Canadian Imperial Bank of Commerce, noted that the flat July reading aligned with consensus expectations as the broader economy decelerated from second-quarter momentum. Grantham emphasized that these figures now represent trailing data, with market attention pivoting immediately toward upcoming domestic labor force surveys and consumer price index releases ahead of the Bank of Canada’s scheduled interest rate announcement on October 28.
Escalating Tariff Timelines Across North America
The latest economic downgrade follows months of rapidly escalating trade penalties between Ottawa and Washington during Donald Trump’s presidential term. Tensions peaked as a 50% U.S. tariff on roughly $20 billion worth of Canadian imports took effect following the breakdown of bilateral negotiations. Ottawa responded swiftly with matching retaliatory levies ranging from 15% to 50% on more than 800 categories of American goods, covering critical sectors such as steel, aluminum, and technology.
