[asterisk-biz] Looking for Canadian calling card DID's

This is an interesting scenario, US DID with 20 channels (didsale) are @8.99 (no limit, no surharge per min) each. We are looking for Canadian DIDs with at least 5 channels, but some how the dollar (compared to US DIDs and Canadian counterparts) value doesn't match. Many of the Canadian DID providers are offering Canadian DIDs with $5 and extra channels for $20 to $30 per month.

I am missing anything here? Any one could suggest a cheaper deal like didsale for Canadian DIDs?

List of cities we need Canadian DIDs are :

Toronto
Brampton
Hamilton  
New Market
Oshawa
Toll Free DID Canada/USA

Thanks.
