AI Analysis: Advertising and related services, e-commerce sales

Executive Summary

Canada's Advertising and Related Services sector (NAICS 5418) experienced robust growth from 2016 to 2024, with total sales rising 57% to $13.4B while e-commerce sales surged nearly 4x from $344M to $1,357M. E-commerce's share of total sector revenue more than doubled from 4.0% to 10.1%, signaling a structural shift toward digital channels that consistently outpaced overall industry growth. All three tracked metrics show exceptionally strong positive correlations (r = 0.927–0.982), confirming that e-commerce expansion and broader sector growth moved in near-perfect lockstep across the period.

Key Findings

• E-commerce sales in Canada's advertising sector grew by approximately 295% over 8 years, rising from $343.7M in 2016 to $1,357M in 2024 — the highest value on record.
• Total sector sales grew steadily from $8,536M in 2016 to $13,434M in 2024, a 57% increase, but e-commerce growth far outpaced this overall expansion.
• E-commerce as a share of total advertising sales more than doubled, climbing from 4.0% in 2016 to 10.1% in 2024, with an 8-year average of 7.2%.
• All three variables — Total Sales, E-commerce Sales, and E-commerce Share — are strongly correlated, with coefficients ranging from r = 0.927 to r = 0.982, indicating consistent, synchronized growth trends.
• The strongest correlation in the dataset is between E-commerce Sales and E-commerce as a Percentage of Total Sales (r = 0.982), reflecting how rising digital revenues directly drove the sector's share shift.
• E-commerce sales showed wider relative variability than total sales (standard deviation of $376M vs. $1,730M on a much larger base), underscoring the faster and more dynamic pace of digital growth.
• Outlier detection identified the most recent years as the strongest positive deviations from historical norms, confirming that e-commerce acceleration in the advertising sector is a recent and intensifying trend.
