AI Analysis: Quarterly retail commodity sales

Executive Summary

Canadian quarterly retail commodity sales grew 25.8% from $173.4 billion in Q1 2023 to $218.1 billion in Q3 2025, peaking at $219.8 billion in April 2025, with growth broadly shared across most of the 10 NAICS retail sectors. The dataset — spanning 249 commodity categories and 8,664 observations — is highly right-skewed, with a small number of aggregate categories driving extreme values up to $219.8 billion against a median of just $277.8 million. Sales are heavily concentrated in a relatively small number of top commodity categories, while the bottom-ranked segments contribute only marginally to overall retail volumes.

Key Findings

• Total retail commodity sales grew by 25.8% over the study period, rising from $173.4 billion CAD in Q1 2023 to $218.1 billion CAD in Q3 2025, with a peak of $219.8 billion recorded in April 2025.
• The dataset covers 249 NAPCS commodity categories across 10 NAICS retail industry sectors, generating 2,490 unique time series over 12 quarters of national-level data.
• The distribution of sales values is heavily right-skewed: the mean of $2.71 billion is nearly 10 times the median of $277.8 million, reflecting the outsized influence of a small number of high-volume aggregate categories.
• 14.4% of all records (1,244 out of 8,664) were flagged as statistical outliers using the IQR method, with 1,009 classified as extreme outliers exceeding $2.77 billion — largely driven by aggregate categories such as 'Total commodities' and 'Retail trade [44-45]'.
• The middle 50% of sales values spans approximately $1.08 billion (from $54.6 million at the 25th percentile to $1.14 billion at the 75th percentile), confirming high variability even among typical observations.
• Most retail industry sectors show strong positive correlations with one another, suggesting that the majority of sectors respond similarly to shared economic cycles and seasonal trends.
• Retail sales are highly concentrated, with the top 10 commodity categories accounting for a disproportionate share of total sales volume, while the bottom 10 categories represent niche segments with minimal contribution across the full 2023–2025 period.
