It's expensive to get oil out of the tarsands. I'm wondering how far oil has to drop before the sands are no longer profitable.

A friend who worked for Petro Canada told me they can produce it now for just under $25 / barrel, so they got some wiggle room still. However, it if did drop to $30, the $100 billion or so in future investment would disappear, causing a huge drop in Alberta's economy.
