Where is the Vonage Price reduction for Canada? Our dollar is @ par with the US$

I don't get Vonage, they have attached a premium to CDN service since its inception - and now the CDN $ is very close to @par with the US$ - and still CDN pricing hasn't changed.

24.99 - unlimited premium service on Vonage.com
39.99 - unlimited premium service on Vonage.ca


What gives Vonage?

*Update (Oct. 25/2007) - I spoke to a CSR at Vonage today and they said that they price according to competitive local rates. This is the most ridiculous thing I have ever heard, IP has no boundaries, there are no additional costs to operate in Canada, yet they continue to overcharge Canadian customers.
