I haven't been able to find their price list, but Marketwire and Canada Newswire typically cost you about $500 per release. Assuming the Gov. only releases on weekdays, and that there are 260ish workdays in a typical year, that's about $3,500 or 7 news releases per day--or 3 1/2 if they send each release to both outlets. Seems rather a pile, and quite redundant giving the multitude of other communications tools there are at the Gov's disposal.
