Monty and Conrad Black took control of Ravelston Corp., which controlled Argus Corp., which controlled Standard Broadcasting, from the widows of J.A. MacDougald and W.E. Phillips.
1982
CJAD and CJFM studios were relocated at 1411 Rue du Fort.
1984
On June 22, CJAD began broadcasting in stereo, using the Motorola system.
1985
Slaight Communications (J. Allan Slaight) purchased Standard Broadcasting Corporation Ltd. from Argus Corp. (Conrad & Monty Black). The sale was announced March 29 and approved by the CRTC in November.
1986
Standard Radio Inc. was set up as a division of Standard Broadcasting Corp. to own and operate the company’s radio stations.
1992
CJAD began simulcasting its programming on CKTS-AM Sherbrooke.
1998
CJAD lost all four of its towers in the Ice Storm of '98 in January. Immediate arrangements were made to borrow the La Prairie transmitter site of CFMB, and CJAD began broadcasting on 1410 kHz. CFMB had moved the previous year from 1410 to 1280 kHz, using the former CJMS 1280 transmitter site. The CFMB 1410 site had not yet been dismantled. CJAD didn't stay on 1410 for long as the directional pattern on that frequency missed most of CJAD's Anglophone audience in West Montreal. The next move was to 990 kHz. CJAD made arrangements with CHUM-owned CKGM to use its transmitter and frequency temporarily.
2001
CJAD was given approval to operate a transitional digital radio undertaking. Transmitters would be installed at Place Ville-Mare in Montréal and at Laval. The EUREKA-147 digital audio broadcasting system would be employed. The transmitters would operate on 1454.56 MHz with an effective isotropic radiated power of 1,400 watts at Montréal and 1,594 watts at Laval.
2002
Standard Radio took ownership of CHOM-FM from CHUM Ltd.
