A Canadian regulatory ruling that effectively stops small Internet providers from offering unlimited downloading must be revised, Industry Minister Tony Clement said on the social networking site Twitter.

True. CRTC must go back to the drawing board, Clement wrote late Wednesday when asked whether he would overturn the decision if the regulator does not back down. http://twitter.com/#!/TonyClement_MP

The Canadian Radio-television and Telecommunications Commission ruled last week that BCE Inc, the parent of Bell Canada, could charge wholesalers that lease bandwidth on its network on the same usage basis it charges its own customers, minus a 15 percent discount.

The ruling would force small carriers to pass along the extra cost and prevent them from offering cheap package plans to their customers.

Canadian Prime Minister Stephen Harper expressed immediate concern and ordered a review of the ruling.
