GLOBAL NEWS 1 - Canada

Following the launch of BC1, its 24 hour local news channel for British Columbia, Shaw Media plans on launching a national news channel with a twist.
Using its existing newsrooms across the country this news channel will present local news cut-ins at the top of the hour and a continuous data feed of hyper-local headlines and community events for each market. With the ability to cover live, breaking news at the local, regional or national level, Global News 1 will be like no other service on the dial.

So essentially viewers in Toronto will get a Toronto specific cut-in at the top of the hour and see Toronto local headlines, traffic and weather scrolling on the screens continuously even after the cut-in ends and returns to the national feed, all the while viewers in Calgary and Edmonton will get a market specific feeds on their screens. (Sorta seems how the Weather Channel uses its cable headends to feed specific weather data, forecasts and warnings on screen to 1000s of markets across the US whilst the national feed plays-out.)

This will result in 12 or more specific feeds across the country. Global also plans to create newsrooms in undeserved cities like Charlottetown PEI and create partnerships with independent stations in other cities such as on St Johns NFLD.

Sounds pretty cool and different from the current all news channels that exist in Canada like CBC News Network, CTV News Channel and the existing local news channels CP24 (Toronto) and Global's BC1 (British Columbia).

Global says that the channel will use BC1 as the launching point for the network if approved by the CTRC.

Can anybody please explain to me with CTRC, and why is it every channel that wants to air in Canada needs to be approved by the authority... and Why the channel needs to be Part-Canadian-owned?

These are essentially protectionist measures designed to prevent Canada -- particularly Anglophone Canada -- from being completely drowned out by the huge U.S. media market next door. That's why CTRC regulation has historically been rather heavy-handed.

The CRTC is a regulatory body that is like the FCC in the US or Ofcom in the UK. Broadcasters are required to have licences to operate just like any other business. And yes, the CRTC is much more protectionist compared to the other regulators because most Canadians prefer content produced by the US industry over home-made programming. US TV shows consistently beat Canadian-produced shows in ratings with some exceptions during the year.
As for ownership, it's protectionism again. Many channels use names from the US such as CMT or Food Network through licensing agreements but are completely owned by Canadians or Canadians own a majority of that channel.
With that said, many non-Canadian channels are licensed to air in Canada. Basic cable/satellite packages offer the big 5 US terrestrial networks and we're offered many foreign news channels such as BBC WN, AJE, CNN/US, FNC, MSNBC, RT, etc. Foreign language channels from other countries are also available. None of these channels feature Canadian Content nor are they Canadian-owned.
