Natural gas liquids and sulphur products from processing plants, monthly supply — AI AnalysisStatistics Canada Table 25100036 tracks 37 years (1989–2025) of monthly natural gas liquids and sulphur supply from Canadian processing plants across 7 product types and 7 regions, comprising 6,460 non-null records across 24 unique time series. Sulphur dominates the dataset by a wide margin, with a Key Findings

Sulphur is the highest-volume product by a large margin, with a mean monthly supply of 384,248 and a maximum of 760,339 (in thousands of tonnes), dwarfing all NGL categories.

The overall supply distribution is heavily right-skewed, with a mean of 61,249 versus a median of just 466 and an IQR of only 1,050 — almost entirely driven by Sulphur's outsized values.

Ethane is the most consistent NGL product, with a mean of 698, a median of 901.5, and a relatively low standard deviation of 507, indicating stable long-term production.

Propane and Butane show high variability relative to their medians (medians of 53 and 37 respectively, with standard deviations of 440 and 271), suggesting significant seasonal or regional fluctuations in production.

No extreme outliers were detected across all 6,460 records using the strict 3× IQR method, indicating consistent data reporting and smooth production trends over the 36-year period.
