The 1 year warranty on the refurb is the same duration as a unit purchased retail. It used to be 90 days years ago.
The EU may have a 2 year warranty, but it's also padded into the price, which is higher than the US. A short warranty makes sense because it covers the burn-in period where there are more failures. A mandatory longer manufacturer warranty is a enforced extended warranty, and companies don't offer extended warranties to lose money.
Personally, I've never had anything Canon fail within a 2 year window. I've had many Canon lenses and bodies and the only things I've had to have done were to replace a 5DIII board due to an reported camera error and some rubber pieces (on the 5DIII and on a 24-70 II). The 5DIII board failure happened in year 3, plus I bought it gray, so I've come out way ahead. Warranties also don't cover user-induced damage/failure, so it's scope is limited.
