Local Delivery Unit Boundaries (LDU)

Coordinate system: 4326 - "WGS 84"

Abstract:

The Local Deliver Unit (LDU) boundary file represents neighborhood areas associated with six digit postal code assignments. The LDU is derived from various CanMap topographic features and enhanced Canada Post data.

The boundary file is generated from point addresses with six-digit postal codes attribute assignments. The LDU Boundaries allow for a many to many relationship. For example, one postal code may be represented by more than one LDU boundary and one LDU boundary may be associated with multiple postal codes.

This boundary file has an accompanying Postal Code Lookup Table available which contains primary and other postal codes for buildings or discrete areas with multiple postal codes in the LDU file.
