Time Warner’s AOL Division plans to begin offering VoIP-based telephony in Canada by the second half of the year, turning up the heat in an increasingly competitive telephony market. The announcement comes hot on the heels of a statement on 9 December 2003 in which Time Warner said it was to launch a nationwide voice-over IP-based telephony service in the US sometime in 2004. AOL Canada has more than 500,000 subscribers in Canada and hopes to mount a challenge to domestic heavyweights BCE and Telus Corp. It is not the only firm with aspirations in the internet-telephony market: Primus Communications, a provider of voice and data services, introduced a VoIP option in Canada earlier this month.
