I thought I'd crunch some numbers based on what this fellow in the OP said, and compare that against the gains in the carbon market. For the record, I don't think Canada should persue the carbon market as a means to reduce emissions, but as a means to off-set costs of emssion reduction implementation.
Using the OP figures the range for cutting these costs works out to anywhere between $4.6 Billion and $11.2 Billion, roughly. Just in the last year, the global Carbon trading market grew from $11 Billion to almost $22 Billion. Now the majority of that is being spent in China and India. As they are developing countries under this plan, so industrialized nations gain credit by paying for cleaner technolgy in place of cheaper dirtier technology. $19 Billion of that money is coming from the EU, who is using these credits to meet their pledge.

Renewable energy and energy efficiency is emerging as the fastest growing aspect of the carbon market, jumping from 11 to 26%.
What is unknown is what will happen to the big dogs after 2012. Will China and India remain
exempt from the industrialized nations list. Perhaps could we enter an agreement with nations like Australia and USA, and perhaps the EU, whereby they could green their image or further their reductions by purchasing credits from us? Certainly if we develop the sequestration techniques and technology, hypothetically the credits they would purchase from us, assuming we pay the initial investment to make our targets, could help to offset our costs. Once we are below our own emission standards, countries could further reduce their emissions by purchasing more credits and we could give them our data/technology to use themselves.
If the trend continues, and global emission reductions are met by decreases in the more efficient larger emission countries, we could cash in on this market. I think this might be what Dion is thinking. By making our own fossil fuel industry clean, we can continue to use the infrastructure and energy available easilly to us. As our industry makes money off cleaner technolgy, we can begin to make the move by adding renewables, which only furthers the credits which other countries can purchase from us, and thereby giving renewable energy a larger market share to offset future shortages/cost increases in the fossil fuel industry.
Now this is assuming we use the Kyoto protocol as a cash generator, like I said to offset our own initial costs.
Theres plenty of unknowns in this ramble of mine, but for the time being, some food for thought.
Edit: I just now saw that Sir Richard Branson and Al Gore (snicker all you want) just announced a cash prize to the first scientist to develop the CO2 stripping techniques we're talking about here.
