If you are willing to look at Canadian schools, then McMaster, UWO, and UBC.

UWO’s program is new (they have yet to graduate a cohort) but McMaster’s has been around for a little while (when we we attended a recent open house the program coordinator said that students from the first cohort were getting ready to defend their Ph.D.'s). McMaster’s program is highly competitive to get into receiving around 700 applications for about 60 spots. I don’t know anything about UBC’s program.
The University of Waterloo has a program they call Honours Science, but it is more of a design your own program and doesn’t have the specially designed integrated courses that the other 3 programs do.
