Oh, and an additional snippet of context: Former civilian appointee to the watchdog body for CSIS (Canadian foreign intelligence bureau) was also a literal lobbyist for the oil company Enbridge, at the same time as when CSIS and local police were keeping tabs on pipeline critics. Canadian government, much like the chairman, disavowed any and all wrongdoing. To say they're cozy with the oil industry would be to engage in colossal understatement.

The U of T study used a model to predict emission levels of a group of atmospheric pollutants known as polycyclic aromatic hydrocarbons, or PAHs, which can be highly carcinogenic.
While previous models assessed the PAHs released directly into the atmosphere during extraction of bitumen from oilsands numbers that tend to fall within acceptable regulatory levels this study included indirect pathways for the pollutants to enter the air, such as evaporation from tailing ponds.
Tailing ponds are not the end of the journey for the pollutants they contain. PAHs are highly volatile, meaning they escape into the air much more than many people think, Parajulee said.
The model also factored in additional PAHs released during the transport and storage of other waste materials from oilsands operations.
Andrew Read, a researcher with Pembina Institute, an environmental watchdog, is a member of the joint oilsands monitoring program rolled out two years ago by the federal and provincial governments.
He doesn't believe there is enough funding to appropriately monitor emissions.
"We are not at the world-class level to really be championing that," he said. "There is a concern there that we are not doing the effective monitoring that is necessary to really understand the full impact on the environment."
