Community Health Service Area (CHSA) boundaries; 2018 boundary configuration.

On April 1, 2019, the Ministry of Health released a new geography classification that introduces community-level geographies nested within the Local Health Areas.

The CHSAs are a mutually exclusive and exhaustive classification of the land area in BC. CHSAs are contiguous (land area is geographically adjacent) and fit within the existing geographical hierarchy (cannot violate higher-level geography boundaries such as the Local Health Area).
