A group of Canadian companies and unions is asking the the government to probe the video streaming company Netflix.

A working group of formed by the nation's telecom regulator—Canadian Radio-television and Telecommunications Commission—called on the commission to investigate Netflix earlier this month. The working group consisted of industry representatives.

The letter recommended that the CRTC open a proceeding to see whether Netflix' reporting requirements should be expanded and whether it should have to pay a tax to support Canadian broadcasting.

"The Working Group believes indeed...that foreign over-the-top services are becoming a significant presence in the domestic market," the letter said.

Netflix has tussled with Canadian ISPs over data usage caps, and decided this month to downgrade its video quality in Canada so it consumes less bandwidth.
