1946
The CBC announced it hoped to have a 250 watt FM transmitter in operation in Vancouver by October. Equipment would be installed in the CBC studios in the Hotel Vancouver. The FM transmitter would be the first permanent unit on the west coast, although a portable unit was used recently by CKMO to broadcast from a moving auto during a Jubilee parade. CBR officials hoped their move would spark interest in FM broadcasting and help promote further desire among the public for information about FM receivers. The CBC FM transmitter would broadcast the same programs as CBR and would be utilized as an alternative to the regular station equipment. It was predicted that the transmitter would reach Greater Vancouver and environs, and possibly as far as Vancouver Island.

1947
The first FM transmitter west of Toronto was to be set up in the Hotel Vancouver, home of CBR. It was expected to be operational by March. VE5FG would carry the entire CBR-AM service on 105.7 MHz with power of 250 watts. Arthur B. Ellis, senior engineer for the CBC Pacific region said the 40 foot antenna, built by Marconi, would be erected on the ridge of Hotel Vancouver's roof, one of the highest points in the city.

A 1,000 watt FM transmitter was expected to arrive in Vancouver in late September or early October.

The first FM transmitter west of Toronto went on the air in Vancouver on December 12 (testing since November 21). CBC engineers estimated they may be around 100 FM sets in the area to be covered by VE9FG. A special program marked the first day of operations. Normally the station would duplicate CBR's 17 hour program schedule (also broadcast over CBRX on shortwave). Facilities were set up on the 7th floor of the Hotel Vancouver and the 40 foot antenna was on the roof. VE9FG operated on 105.7 MHz with a power of 1,000 watts.

On December 4, the CBC held an open house to show off its revamped Vancouver headquarters at 700 Hamilton Street. The renovations took four years and $65 million to complete. The corporation considered selling the building and constructing a new facility, but that would have cost $100 million or more. It also would have been difficult to find a new location as central as the existing facility. The old building was still there, but it was kind of hidden behind a new wing in front. The new 25,000-square-foot space housed all local news gathering operations - TV, radio, English, French, and internet.

Johnny Michel was CBC Vancouver's managing director.
