AI Analysis: Chartered banks, mortgage loans report, end of period, Bank of Canada

Executive Summary

Chartered bank mortgage loans in Canada have grown an extraordinary 6,558% over 43 years, rising from $31,715 million in January 1982 to a record $2,111,534 million (approximately $2.1 trillion) by October 2025. The dataset, spanning 13,982 observations across 80 data series, reveals a heavily right-skewed distribution where the mean of $30,077 million dwarfs the median of $498.5 million, reflecting the dominance of large aggregate totals over granular subcategory values. Two notable anomalies punctuate the long-term growth trend: a striking +40.3% single-period surge in October 2011 and a +10.1% jump in July 1993, both likely tied to data reclassifications or structural reporting changes.

Key Findings

• Total chartered bank mortgage loans outstanding grew from $31,715 million in January 1982 to a record high of $2,111,534 million in October 2025 — a 6,558% increase over 43 years.
• The dataset is heavily right-skewed, with a mean of $30,077 million versus a median of just $498.5 million, driven by a small number of very large aggregate totals reaching $2.1 trillion.
• The standard deviation of $147,918 million is nearly five times the mean, underscoring extreme variability across the 80 data series that span detailed subcategories and national totals.
• The most significant anomaly in the dataset is a +40.3% month-over-month surge in October 2011, when total mortgage loans jumped to $917,456 million — likely reflecting a data reclassification rather than organic lending growth.
• 75% of all 13,982 records fall below $7,449 million, while the bottom 25% are at or near zero, illustrating how the dataset mixes granular subcategory breakdowns with large consolidated totals.
• Growth has been continuous and uninterrupted to record highs as of October 2025, reflecting over four decades of rising Canadian home prices and expanding chartered bank mortgage portfolios.
• Only 3 negative values exist across the entire dataset, representing minor credit loss adjustments, with the lowest recorded value at -$398 million.
