1967
Radio 1540 Ltd. (Johnny Lombardi & partners) opened CHIN-FM on 100.7 MHz with 50,000 watts effective radiated power. CHIN transmitter was a non-directional signal from a 310 foot tower. Studios were at 367 College Street, in the building that house the Lombardi family supermarket, and CHIN-AM.

1968
At licence renewal time, CHIN-AM-FM sought to have more ethnic programming. President Johnny Lombardi said that building a substantial audience among the city's various ethnic communities could not be established with English language broadcasts that merely stressed European music. The BBG told him for such a change he would have to make a specific application to the board to increase the percentage for foreign language programming. CHIN was now authorized for 20% and could apply for 40%. The board noted that CHIN-AM was a daytime only operation and that the 24-hour CHIN-FM signal had been recently added. There had been problems with the FM operation because it interfered with some TV signals in the city. Special traps were purchased and installed to eliminate the interference.

On May 28, Radio 1540 Ltd. was authorized to broadcast on AM and FM, languages other than English and French for periods that in the aggregate exceed 20% but do not exceed 40% of the broadcast time per week.

1969
On November 5, the transfer of some shares of Radio CHIN-FM Ltd. was denied. The application would have seen the transfer of 324 common shares from John B. Lombardi to John Longo and one common share from Lombardi to Antonia (Lena) Lombardi.

1970
On June 17, permission was granted for a share transfer in both Radio 1540 Ltd. and Radio CHIN-FM Ltd. 25% of the shares in each company would transfer from James D. Service to John B. Lombardi. This decision however, does not change the Commission’s March 25 decision regarding reassignment of these frequencies.

1973
On May 30, CHIN-FM’s application to move from 100.7 to 107.1 MHz (with 50,000 watts) was denied.

On December 14, most of Toronto’s FM and TV stations were given permission to move their antennas to the CN Tower once construction is completed.

1976
On May 24, testing began from the brand new CN Tower, 301 Front Street West. CHIN-FM began broadcasting officially from the tower just after midnight on May 31. With the increase in antenna height to 1,380 feet, CHIN-FM's effective radiated power was reduced from 50,000 watts to 4,000 watts. CHIN-FM also switched from monaural to stereo broadcasting. The station installed two 2.5 kw AEL transmitters in a "hot standby" configuration. Either transmitter could operate as the main or the alternate. The switching system was fully automatic and actually sought out the best system components, switched them to the on-air position and signaled the information back to the studio operator. Chief engineer at this time was Paul Hunter.

CHIN-FM again applied for a change of frequency to 107.1 MHz with effective radiated power of 40,000 watts. The application was turned down. The CRTC felt CHIN's coverage had been substantially improved by transmission from the CN Tower.

1977
Johnny Lombardi was one of several applicants for a new multilingual television station in Toronto. All of the applications were denied by the CRTC.

1978
To avoid power outages a new generator was installed at the CHIN studios.

The CRTC again accepted applications for a multilingual TV station in Toronto. This time there was a winner. Dan Ianuzzi's Multilingual Television (Toronto) Ltd. won the licence on December 27. Johnny Lombardi did not participate this time around.

1978-79
Bill Evanov left CHIN-AM-FM for Burlington's CING-FM.

1979
Chief engineer Trevor Joice reported the installation of a new stereo production console, Ward-Beck R1200, a 12-input unit with many extras. CHIN also installed a new McKay Dymek DR-33 shortwave receiver. It would be used to pick up three international news broadcasts especially for CHIN from Italy's RAI.

Johnny Lombardi had plans for new studios and offices for CHIN Radio. Some time ago he had purchased an old Loblaw's supermarket across the street from the stations. He had hoped it would be the home of the television station that he never got. The new facility would be a people-oriented community centre, housing CHIN-AM and FM, as well as television production facilities. The modern exterior of the new 80' x 184' building would be of reflective glass - a mirror of its surroundings.

1981
Kirk Stewart left CHIN's engineering department for CJJD in Hamilton. Trevor Joice became director of engineering at CHIN to allow vice-president Paul Hunter to be more active with PWH Electronics.

1982
CHIN-FM installed a Uni-Tel remote control system that linked the studios with the transmitters on the CN Tower.

CHIN was making use of satellite technology by broadcasting daily transmissions from various parts of Europe. CHIN could also communicate with the point of origin, or relay their own transmissions.

CHIN had plans to build a bilingual newsroom that would combine the existing two newsrooms into one, for the use of newscasters skilful in two or more languages.

1985
In March, the CRTC held public hearings across the country to establish an ethnic broadcasting policy. CHIN had been a mini United Nations for a long time and the new Ethnic Broadcasting Policy that came about from the hearings, brought recognition to what CHIN has been all about, and encouraged similar services across the country.

Johnny Lombardi received a civic award of merit from the City of Toronto. Among his achievements: founding of 'Italian Days'at Ontario Place and Canada's Wonderland.

1986
CHIN-FM was authorized to increase the amount of ethnic programming aired to 97.2%.

1987
Carl Redhead was vice president at CHIN-FM-AM.

1991
In May, CHIN-AM and FM moved to a new studio location at 622 College Street, almost right across the street from the old facility at 637 College. The new six storey building featured 50,000 square feet of boutiques and professional offices. A senior's residence was built next door. CHIN Radio occupied floors four, five and six. The radio studios were on the fifth floor with FM on the east side and AM on the west side. McCurdy 8800 series consoles were used in the control rooms. Ward-Beck 1200/1400 consoles were used in production studios B and C. Production studio A was an eight-track recording facility, using a Soundcraft 600 console. The new studios featured Studer and Otari reel to reel tape decks, and ITC and BE cart machines. Construction of the actual studios was started prior to Christmas 1990 and the bulk of the work was done in June of 1991. CHIN-FM was able to begin broadcasting from the new facility on May 8 and CHIN-AM followed on the 16th.

David Lee was named chief engineer for CHIN-AM and FM.
