You've hit one of my pet peeves in Canadian politics-calling the Conservative Party, the "tories", because they aren't. The tories were actually the old Progressive Conservative party (remember Joe Clark?). The reason the distinction is important is because the Conservative Party if anything is an incarnation of the old Reform Party/Canadian Alliance more than it was the Progressive Conservatives, although many PC's joined as well when the Conservative Party was founded.
I do agree they are not the Tories, if they were I would not be within a 100 miles of them. That said, while it looked like the merger was a CA/Reform take over, in the end the current Conservative party has more influence from PC people that CA/Reform people. The back room people from the Mulroney era hold a lot of influence as do the Ontario, Alberta, Manitoba and Atlantic provincial PC people.
A large core of the Reform party was a fundamental reform of our democracy - electoral reform, triple E Senate, more power for the MPs etc.... This is all gone from the agenda
