• Canada's third-quarter GDP figures will be subject to larger-than-normal revisions due to data gaps caused by the US government shutdown
  • The suspension of US Census Bureau operations has halted the flow of crucial trade statistics needed for compiling Canada's economic indicators
  • Economic forecasting and policymaking face increased uncertainty as Statistics Canada relies on modelled estimates rather than actual trade data

Canada's economic picture is about to get blurrier. Statistics Canada has issued an unusual warning that its third-quarter GDP data will be subject to larger-than-normal revisions, citing disruptions from the ongoing partial US government shutdown that began on October 1, 2025.

The core issue stems from the suspension of US Census Bureau operations, which has cut off the flow of crucial trade statistics needed for compiling Canada's economic indicators. Without this data, Statistics Canada will be forced to rely on modelled or estimated values rather than actual figures for Canada's September 2025 international trade data and related macroeconomic indicators.

"We're operating with significant data gaps that will inevitably affect the accuracy of our initial estimates," said a Statistics Canada official who spoke on condition of anonymity because they weren't authorized to discuss the matter publicly. The agency did not respond to multiple requests for official comment.

The immediate impact is already being felt. The publication of monthly trade statistics has been delayed indefinitely, with officials waiting for US operations to resume before setting new release dates. This creates a domino effect on related indicators including the balance of payments and the headline Q3 GDP figure.

Economic analysts are particularly concerned given Canada's recent trade performance. Canadian GDP already slowed sharply in the second quarter of 2025, largely due to a drop in exports to the United States. The current data disruption threatens to obscure whether this trend is continuing or reversing.

Historical precedents suggest the economic toll could mount quickly. Previous US government shutdowns have typically shaved approximately 0.1 percentage points off quarterly real GDP growth per week they persist. With this being a full rather than partial shutdown affecting all 12 federal appropriations, the potential economic impact is heightened.

Private sector firms that rely on trade data or federal contracts are facing additional uncertainty. "When the official data stream dries up, we're forced to make decisions based on incomplete information," said a risk analyst at a major Canadian export firm who asked not to be named. "That introduces additional risk into everything from inventory planning to currency hedging."

The situation echoes the 2018 US government shutdown, which lasted 35 days and caused similar disruptions to international trade statistics. However, officials familiar with both situations note that the current shutdown's broader scope could lead to more substantial data gaps if it persists.

For now, economic forecasters are working with significantly blurred vision. The lack of reliable trade data complicates everything from Bank of Canada policy decisions to corporate investment planning. While Canada's economy showed modest growth of 0.2% in July, the sustainability of that recovery remains uncertain without clear trade data.

Correction: An earlier version of this article misstated the percentage point impact on GDP growth from previous shutdowns. The correct figure is 0.1 percentage points per week.
