The position and extents of a parcel of land, usually the smallest unit of land that can be held under an individual lease without a requirement for further subdivision. URBAN blocks are defined as blocks that appear within a division and have division and section identifiers. RURAL blocks do not usually appear within a division, but may do so if they remain from before the division was created. Blocks may have a lifecycle stage or Proposed, Registered, Approved, Occupied or Retired.

PROPOSED: The block is proposed but has not reached any other stage.

REGISTERED: The block appears on a Deposited Plan that has been registered with the Land Titles Office.

APPROVED: The block appears on an Approved Plan that has been signed by the Territory Planning Section and the Project Officer for the development.

OCCUPIED: The block is leased, but does not appear on a registered plan. Leases over unregistered blocks may not be registered at the Land Titles Office, so this stage is used for unregistered blocks with unregistered leases. This normally only occurs in rural areas.

RETIRED: Retirement of a block occurs when it is replaced by another block.

Note that block boundaries may not always align exactly. The legal definition of a block is defined in the Deposited plan.
