A few things to check:

- check /etc/localtime to be sure that it
   matches /usr/share/zoneinfo/Canada/Eastern - if it does then you have a
   very interesting problem
- check that you're running latest tzdata (dpkg -l | grep tzdata), in my case
  I'm running 2007b-0ubuntu0.6.10
- check /etc/timezone to make sure Canada/Eastern is what you configured

If my first tip above checks out then there's no need to check the rest, your 
zoneinfo is fine.

A few other things related to clock:

- run hwclock, if time is not correct run ntpdate to correct system time and
  then run "hwclock --systohc"

Could be GNOME, I run kubuntu on both my laptop and desktop, both switched to 
DST just fine.
