The CBC (Canadian Broadcasting Corporation) has a Free Headlines Service which allows for free news headlines on web sites or intranet sites. Up to three headlines per category, choosing from various news and information categories. Those interested need to apply for the affiliation program. When I read the agreement in the application form, I noted an exclusivity clause, that headlines from other news and general information services cannot be posted on the same site. I did not actually try out the service because I need to think about this clause, but would be interested in trying it.
Alternatively, there is also an RSS feed available for those who want to read CBC headlines individually.
