You have been making a lot of statements of *facts* in a number of threads without ever providing evidence when asked. Do not post here again until you furnish proof.
It twas I that cited the Ceres study...
Growing Land Reclamation Costs/Liability: After 40 years of production, no oil sand companies have yet fully reclaimed the extensive tailings ponds used for holding polluted wastewater. This is because the fine tailings in these ponds take decades to settle out. These tailing ponds, already covering an area the size of Washington D.C., pose risks of contaminating adjoining lands and water resources, and present health problems in downstream communities. Alberta's Directive 74 requires oil sands miners to speed up remediation of existing ponds – an order that creates especially large liabilities for the industry's legacy miners such as Suncor and Syncrude.
The WWF has a campaign going...
Oil sands extraction uses significant amounts of water (2-4.5 barrels per barrel of oil produced), which ends up in toxic tailings lagoons that have never been successfully reclaimed. An analysis using industry data estimated that these lagoons already leak over a billion gallons of contaminated water into the environment each year.

More detail from the actual Ceres report...
In 40 years of oil sands production, no tailings ponds have yet been fully reclaimed. That is because, while mature fi ne tailings settle out after three to fi ve years, the fi ne tailings remain suspended. As a result tailing ponds could substantially alter the surrounding ecosystem by contaminating soil and water sources, presenting both health problems to downstream communities and the potential of a catastrophic breach. This issue is one of the oil sands industry’s biggest long-term environmental challenges, especially for legacy oil sands miners like Suncor and Canadian Oil Sands Trust.
As discussed in Chapter 2, Alberta’s Energy Resources Conservation Board (ERCB) is tightening oil sands tailings management under Directive 74. Th is directive requires mined oil sands producers to remediate existing tailings ponds, where disposal has been completed, within fi ve to eight years, and progressively recycle more tailings in the future. Because fi ne tailings (FT) take as long as 40 years to settle, and current technology is not yet able to expedite this process, companies may be forced to use alternative processes such as bioremediation or Suncor’s proprietary MFT drying and accelerated dewatering process to meet the schedule set by the ERCB.
..If bioremediation were used to treat new tailings production, our analysis indicates that Imperial Oil could see a 6-17% increase in its debt-to-capitalization ratio, and Canadian Oil Sands Trust (COST) could see a 10–26% increase, in order to cover the added asset retirement obligations for existing tailings sands projects.
..Taken together, water management and land reclamation are major issues that get minimal attention on oil sands producers’ balance sheets.
Nigeria = Canada might be hyperbole, but - along with the Nafta arrangement I cited in #245 - Canada does seem surprisingly compliant about doing what it takes to get oil sands up and going. Compare for instance US reaction to a little spillage in its gulf.
“What is happening at the moment in the oil sands of Alberta is kind of like the Gulf spill, but playing out in slow motion,” [said] RiskMetrics study co-author Doug Cogan.

but the issues here a little more important than the usual.
