1962
Chateau Broadcasting Co. Ltd. (C. Sodo, C. G. Stanczykowski and C. Nolin) launched CFMB December 21. The station broadcast on a frequency of 1410 kHz and had a full-time power of 10,000 watts. Studios and offices were located at 2015 Drummond Street and the transmitter site with four towers was on the 2nd and 3rd concessions of La Madeleine Parish. CFMB was “Canada’s First Multilingual Broadcaster”.

Before starting CFMB, Stancykowski did some ethic programming on CHLP and CJMS in Montreal, and on CHRS St. Jean. For the record, the 1410 frequency was previouslly used by CHLP which went silent in 1957.

1965
In addition to ethnic programming, CFMB also played music and was known as "The Good Music Station".

CFMB was an independent and had no network affiliation. Casimir G. Stanczykowski was president, manager, commercial manager and program director. Al Pascal was production manager. Bob Dowling was morning man. Stew McIssac was news director and Bob Boulanger was sports director.

1968
CHUM Ltd. had its application to purchase CFMB from Chateau Broadcasting Ltd. denied on December 24.

CFMB moved to new “state-of-the-art’’ studios and offices at 35 York Street in Westmount.

1981
Casimir G. Stanczykowski died in a traffic accident on July 12. Founder of CFMB, he was a pioneer in Canadian ethnic broadcasting and had recently become president of the Canadian Association of Ethnic Radio broadcasters. He was 53.

1997
On February 21, CFMB was authorized to move from 1410 kHz to 1280 kHz and to increase power from 10,000 watts to 50,000 watts. The multicultural station expected that the new 1280 transmitter site would be completed in June. A competing 1280 kHz application by T.A.M.M. Communications for a French-language station to serve the south shore from St. Constant was denied.

CFMB began testing on the new 1280 frequency in the spring and moved there permanently in September. CFMB used the old CJMS 1280 frequency and transmitter site. CJMS 1280 left the air in 1994. The six towers were in St. Mathieu, south of St. Constant, about 15 km southwest of the old 1410 facility.
