Uh, no. As someone that's worked on these switches (and transport gear associated with them), you can still go from one end of the United States to the other without hitting a packet switch. There's still thousands of them out there.
I'm not sure if you can get native DSx/SONET backhaul in Canada from one end of the country to the next, but I know it's a similar situation there with end offices. Bell also operates a pretty extensive network of DMS-250s, so a lot of telecommunications traffic hits circuit switches regardless of its destination.
