AI Analysis: Estimates of specialized greenhouse operations, greenhouse area, and months of operation

Executive Summary

Canada's specialized greenhouse industry has grown substantially from 2007 to 2025, with total greenhouse area reaching approximately 675.8 million square feet nationally, even as the number of operations declined from a peak of 32,021 in 2013 to 24,056 by 2019 — signaling consolidation into fewer, larger facilities. Fruits & Vegetables greenhouses dominate by physical footprint (23.9 million sq m) despite having fewer operations than Flowers & Plants (985 vs. 1,526), reflecting a trend toward large-scale food production. The dataset spans 19 years across 6 Canadian geographies and reveals strong regional variation, with the most current 2025 data providing a comprehensive picture of a maturing, increasingly concentrated industry.

Key Findings

• Canada's total greenhouse area grew from a low of ~422.6 million sq ft in 2008 to a peak of ~675.8 million sq ft in 2025, representing substantial long-term physical expansion of the industry.
• The number of greenhouse operations peaked at 32,021 in 2013 — the dataset's strongest statistical outlier (z-score of 2.79) — then declined to 24,056 by 2019, indicating industry consolidation into fewer but larger operations.
• Fruits & Vegetables greenhouses cover more than 3x the area of Flowers & Plants operations (23.9 million sq m vs. 7.5 million sq m) in 2025, despite having fewer total operations (985 vs. 1,526).
• Square feet and square metres measurements are perfectly correlated (r = 1.0) as expected, while the wide gap between mean (~23.4M sq ft) and median (~7.7M sq ft) confirms a right-skewed distribution driven by a small number of very large greenhouse operations.
• Approximately 17% of records carry data quality flags (F = too unreliable, x = suppressed, E = use with caution), which should be considered when interpreting regional or sub-category breakdowns.
• The dataset covers 6 geographies — Canada, Atlantic provinces, Quebec, Ontario, Prairie provinces, and British Columbia — enabling regional comparisons that reveal which provinces drive national greenhouse trends.
• Across all estimate types, distributions are heavily right-skewed, with overall mean values (~9.87 million) far exceeding medians (~676,863), underscoring that a small number of very large operations significantly influence national averages.
