Well.. I'm in Quebec, Canada and just tried it. Works for me.

Unless they plan to remove support for Canada at a later time...

Really? I thought they were only rolling it out in the U.S. at first. I don't see it in my gmail here in Canada. Here's to hoping..

I had to install the plugin first by going to gmail.com/call, then after restarting my browser, the call phone line appeared in my google chat panel.

I've already installed the plugin a couple of days ago and I tried to reinstall it. It just doesn't work. I'm in Quebec. I am eagerly expecting it.

I don't know what the setup is here at work, but it worked for me and I am in Canada....
