He probably means "Number of Canon facilities near damaged nuclear powerplants". 
But don't worry, Canon "only" produces printers in Fukushima. The DSLRs are made in Nagasaki...
Anyway, as long as Canon applies the same level of quality control to all of their facilities, it doesn't actually matter where your DSLR is from. So far, I'm not aware of any differences between Japanese and Taiwanese Canon cameras.
We would hope . . . I prefer it not be the "My CR-V was made in Japan so it's better than a US CR-V" argument, which is BS
I'm sick of the "if it's 'made in China' it's crap" argument because it's bunk.
QC is up to the company authorizing the sale of the goods, not the people they buy from.
Perhaps the *ONLY* good thing to come out of the quake is that manufacturers of high-end products will diversify their facilities locations' to hedge against disaster, yet strive to maintain existing Quality (with a capital Q).
In certain industries, the country of origin can say a lot, at least on a statistical level. Japanese cars tend to be more reliable than American ones almost any day of the week (though Toyota seems to be hell-bent on changing this!)... Japanese guitars (of certain vintages) are better than American guitars (of certain vintages) are better than Mexican guitars (because they only get to make the cheap models)... And, depending on the model and company of origin, Korean guitars can span the entire gamut. Obviously, it not only matters where, but when it came from.
China used to be considered the "dumb" manufacturers/product-stamper-outers way back in the day, but as their universities seem to be pumping out 50:1 ratios of engineers compared with the US now, their quality has improved. Many of the items produced there are still created with ridiculously low wages, long working hours, and dangerous conditions (*coughFoxconncough*) but at the very least, they now have good engineers employed on the higher-up staff to make sure things go right. I'm sorry to say that my own country is letting all their old and experienced engineers retire while either hiring foreign ones, or just doing without them altogether.
