Reclamation Area with "Do not disturb" signOur Challenge

Mining disturbance in Alberta's oil sands region has significant land impacts. Industry is legally obligated to reclaim all disturbed land to a productive state, and return it to the Government of Alberta. Mines are often in operation for decades and reclamation activities on these sites can subsequently take decades to complete.

Our Actions

As the oil sands industry has matured, reclamation efforts are accelerating. As of December 31, 2012, about 77 square kilometres are under active reclamation, and significant investment by industry and government enables continual improvement in reclamation technology and techniques.

Fast Facts

The map to the right shows that, while the oil sands underlie a 142,200 km2 area in north and eastern Alberta, the surface mining area is limited to a 4,800 km2 region near Fort McMurray -- 767 km2 of which has been disturbed by oil sands mining (~0.2 per cent of Alberta's boreal forest)

  • About 77mk2 is under active reclamation.
  • Industry has planted more than 12 million tree seedlings towards reclamation efforts.

80 per cent of the oil sands are accessible by in situ methods only (bitumen is separated from the sand underground and pumped to the surface).

  • In situ's land disturbance is 10 to 15 per cent of a similar sized mining operation and produces no tailings ponds.

The Reclamation Process

In 2009, new definitions were introduced to better track the level of land disturbance and reclamation progress to date.

Certified Reclaimed - 104 hectares
If an area meets stringent requirements for reclamation, regulators will issue final certification and the land is returned to the Crown as public land. To date, one area called Gateway Hill is certified reclaimed.

Permanent Reclaimed - 5,042 hectares
Landform design, soil placement, and revegetation are complete (for both land and aquatic ecosystems). Companies must use local plant species to target the return of local boreal forest ecosystems. Soils are tested and tree and shrub growth is monitored for 15+ years. When ecological trends are achieved, the company can apply for reclamation certification. 

Temporary Reclaimed - 1,227 hectares
Some areas are reclaimed and revegetated to grasses for the purposes of stabilization and erosion control. These areas may also see future distrubance.

Soils Placed - 1,447 hectares
Soils have been placed as directed by each facility's reclamation and soil placement plans, as approved by regulators.

Ready for Reclamation - 372 hectares
Areas that are no longer required for mine or plant purposes and are therefore available for eclamation. Reclamation activites have not begun.

Disturbed - 55,902 hectares
Land is still part of the active operations of a facility.

Cleared - 20,435 hectares
Land is cleared of vegetation, but the soil is relatively undisturbed. In forested areas, the trees are harvested and some of the smaller wood may be conserved for use in reclamation.

Long-Term Planning

Before any mining project begins, industry must develop and receive approval for closure plans that outline how affected areas will be reclaimed.

Mine operators must provide reclamation security as a guarantee that reclamation work will take place. As of June 30, 2013, government held over $1 billion in reclamation security for the oil sands industry.


Once reclamation is complete, monitoring activities begin. It can take 15 or more years to effectively establish a successful ecosystem.

Reclamation certificates are only issued when long-term monitoring demonstrates the reclaimed land meets the objectives of equivalent land capability.
