There is not much information on the web concerning Thorium Power Canada.
http://www.thoriumpowercanada.com/
Wonder if anyone here has more information.

Looks like they've been in business a while. Can you load thorium into CANDU reactors? The Forbes article noted retrofitting an existing reactor.

From last July. Still on their website. Maybe the deal is going through. Seems to me that a lot of these small nuke companies are selling vaporware.

Yes.
But thorium is a strong neutron absorber, so if a large fraction of the core load is thorium, you need to use enriched fissile material (uranium or plutonium) to get it to go critical and burn for a useful length of time.

China’s Third Qinshan Nuclear Power Company (TQNPC), China North Nuclear Fuel Corporation (CNNFC) and Nuclear Power Institute of China (NPIC) combined forces to assess the commercial and technical feasibility of using thorium fuel in CANDU reactors.
In 2011 an expert panel appointed by the China National Nuclear Corporation concluded that CANDU technology is the ideal nuclear reactor design to further China’s nuclear power program using thorium as an alternative nuclear fuel source.

A surprising development is that the UK, the biggest holder of reactor grade plutonium, have not only given up on fast reactors, but also on evaluation of calandria design which could make profitable use of plutonium with thorium. Possibly they are waiting to see the results of Chinese attempts!
For fast reactors they may be evaluating PRISM.

Okay, found some more information
http://www.google.com/patents/US20100067644
http://nextbigfuture.com/2013/07/the-tp ... actor.html
There was more information on the web a few days ago but now its gone.
You can download files in pdf format.

Figure 23 From patent file.
Looks like Plutonium and U235 gets burned up in 50 years. Is this correct?

It looks like they use only the first modular to start the burn with U and all other add on modular's have TH. Is this true?

The National Physical Laboratory published a position paper that decided that since no significant uranium and thorium resources exist in the UK there is no point in moving towards a thorium fuel cycle.
Frankly I agree with there assesment in the short term, the once througgh UOx cycle is still the best one.

Especially with seawater extraction closing in.
