Consumer Price Index, monthly, not seasonally adjusted — AI AnalysisStatistics Canada's Consumer Price Index dataset (Table 18100004) spans over 112 years of monthly price data from January 1914 to January 2026, encompassing 187,456 records across 358 product categories and revealing a dramatic 2,703% rise in the All-items CPI from 5.9 to 165.0 over that period. PriKey Findings

The All-items CPI rose from 5.9 in May 1914 to 165.0 in January 2026 — a 2,703% increase over 111 years, with the most recent peak recorded at 165.4 in late 2025.

The dataset contains 187,456 fully complete records (zero missing values) across 358 product and product group categories and 1,345 unique monthly observations.

CPI values range from a minimum of 3.10 to a maximum of 477.00 (a spread of 473.90), with a mean of 89.23, a median of 93.40, and a standard deviation of 47.08, reflecting over a century of cumulative inflation.

Correlation analysis of 94 product groups found that the vast majority are highly positively correlated with one another, indicating shared inflation drivers such as energy prices, labour costs, and supply chain factors across the Canadian economy.

Outlier detection on the All-items CPI identified 27 anomalous months out of 1,345 (approximately 2%), defined as monthly changes exceeding ±2.33% — roughly three standard deviations from the average monthly change of +0.249%.
