I was working for AECL back in the late 90s. China CANDU and Canadian CANDU are based on the same design. It is not an issue of regulation in that CANDU reactors in China are built to Canadian standards. The same as US designed reactors built in China are built to US standards.
The China builds are cheaper due to lower labour costs and they are newer builds with newer build techniques. More modular units built off site then welded together on site.
The other issue with the price of a CANDU is Heavy water, it is around 20% of the cost of a reactor. It is a strategic asset, the specific size of the Canadian stockpile is not public. However you put a price on this is to some extent arbitrary.
The last nuclear project in CANDU in Canada was Darlington. The problem was Ontario Hydro raised power rates. Industry responded by refurbishing factories and becoming more energy efficient. Ontario Hydro then said, oh that is not good, we don't need Darlington as soon as we planned, lets slow the entire project down. End result is financing costs went way up. Best thing would have been to bring it online as quickly as possible and get it producing electricity even if it is not as profitable as one would like.
Lets not do the same thing with site-C as Ontario Hydro did with Darlington. Build the dam thing, get it into production and starting to pay its way as quickly as possible.
