Executive Summary

Canadian chartered bank Home Equity Lines of Credit (HELOCs) grew steadily from $3.58 million to $5.41 million in total value between Q1 2019 and Q3 2025, representing a significant multi-year expansion in home equity borrowing. The dataset, spanning 1,036 records across 37 HELOC sub-categories, reveals a strongly right-skewed distribution and near-perfect correlations between combined mortgage-HELOC products and total lending, suggesting a structural shift away from standalone products. Fifteen quarters were flagged as statistical outliers, with October 2025 recording the peak value of $2,050,330 (Z-score of 2.42).

Key Findings

• Total HELOC values increased by approximately 51% over 28 quarters, rising from $3,581,382 in Q1 2019 to $5,405,433 in Q3 2025, reflecting sustained growth in home equity borrowing.
• The dataset is strongly right-skewed, with a mean of $308,159 versus a median of $121,664, driven by a small number of high-value categories reaching up to $2,050,330.
• 75% of all 1,036 records fall below $411,350, while the standard deviation of $427,364 confirms high variability across the 37 HELOC sub-categories tracked.
• A near-perfect positive correlation (r=1.0) exists between 'Combined mortgage and HELOC plans' and 'Total, loan-to-value ratio,' while standalone mortgage products show a strong negative correlation (r≈-0.998) with total LTV ratios, indicating a product mix shift over time.
• 15 quarters were identified as statistical outliers (Z-score > 2), with October 2025 representing the most extreme data point at a Z-score of 2.42.
• The 37 HELOC sub-categories span LTV ratio bands (0–50%, 50–65%, 65–80%, 80%+), combined vs. standalone loan structures, and insured vs. uninsured products, providing granular insight into the composition of chartered bank home equity lending.
• Quarter-over-quarter percentage change analysis identified anomalous swings at specific periods, suggesting episodic acceleration or contraction in HELOC balances beyond normal seasonal patterns.
