1980
CISL (C-Isle) began broadcasting on May 1 at 6:00 a.m.

Glenn Crouter was at C-ISL (son of CFRB Toronto's Wally Crouter).

1981
Monty McFarlane took over CISL's morning show, replacing Arnie Celsie who became program director.

1984
On February 3, CISL was given approval to change its frequency from 940 to 650 kHz and to increase power from 2,500 watts to 10,000 watts day and 7,500 watts at night. The station would also be allowed to change the transmitter site from Richmond (Lulu Island) to Delta (Northshore Boundary Bay). These changes would enable CISL to provide Delta and White Rock with a signal of consistent quality (as it was originally licenced to do).

The Mud Bay (Delta) location that CISL wanted to use for a transmitter site was no longer available. As a result, the station applied to the CRTC for permission to operate on a temporary basis, on 650 kHz with a reduced power of 2,500 watts day and 725 watts night from the existing Lulu Island transmitter site.
 
On July 1, CISL moved from 940  to 650 kHz.

1985
On November 27, the CRTC made a decision on two matters relating to CISL. The first involved an increase in night-time power from 7,500 to 10,000 watts and the relocation of the transmitter site from Mud Bay (Delta) to Lulu Island, approximately 12.5 kilometers to the northwest. The Commission was unable to conclude that the proposed changes would provide White Rock and Delta with a good quality interference-free night-time signal so the application was denied. In order to allow sufficient time for CISL to find a transmitter site that would provide adequate service to White Rock and Delta, the Commission approved an amendment to the station’s licence to operate CISL, on a temporary basis, on 650 kHz, with a power of 2,500 watts day and 725 watts night from the Lulu Island transmitter site.

The other matter related the transfer of shares in South Fraser Broadcasting. At an earlier hearing, it was established that several unauthorized share transfers had occurred since South Fraser was licensed in 1979. As a result of these transfers, Michael Dickinson, who held 60% of the voting shares in 1979, now controlled only 38% of the voting shares through his ownership of 76% of the shares of Dickinson Radio Holdings Ltd. The shares in the holding company were subject to a shareholders' agreement which limited to some extent Dickinson's control over the holding company. The Commission determined that as a result of these share transfers there had been a change in the effective control of South Fraser, and approved the proposed share structure.

1986
John Harris left CISL's community affairs department.
 
1987
On May 26, CISL was given approval to increase night power from 7,500 to 9,000 watts and to change the location of the transmitter site from Delta (Northshore Boundary Bay) to Richmond (Lulu Island). The Commission also approved the addition of a rebroadcast transmitter at White Rock, operating at night only, on  650 kHz with a power of 100 watts.

Jack Simmons was appointed retail sales manager. Johnathan Madill became operations manager and engineer. Both Simmons and Madill had been with CKNW. David Twanow left his operations position to be full-time creative product manager.

Arnie Celsie was program director.

1987-88
Don Percy became CISL's morning man. Other members of the morning show were John Norman (news), Casey White (traffic) and Douglas Miller (weather). Brian Braithwaite took over CISL's mid-day show and Steve Hudson was assigned weekend duties.

1988
On December 27 at 6 a.m., CISL shifted its oldies format from music ranging from 1955 to today as “AM Gold Music Radio” to music ranging from 1955 to 1975 as “Vancouver’s Oldies Station”.

Arnie Celsie became CISL's vice president of programming. Walt Judas moved from the sports department to become program director. Drew Snider joined CISL's news department.

1989
W. (Bill) Waddington was appointed general manager; Janis McInnes, national sales manager; and Alex Adamson, creative services manager.

CISL ended its plan to use synchronous transmission on 650 kHz. In addition to the main transmitter on Lulu Island, a 400 watt transmitter would have been used to improve coverage at White Rock. Chief Engineer Danny Thiel said the problem was solved using the main transmitter.

1991
South Fraser Broadcasting launched CKZZ-FM.

1995
Michael Dickinson agreed to sell CISL and CKZZ-FM to Standard Radio. Dickinson said he needed a rest from radio. He put CISL on the air in 1980 and
Z-95 in 1991.

1996
On May 8, Standard Radio Inc. was authorized to purchase CISL and CKZZ-FM.

2000
Red Robinson wrapped up his 46 year radio career at CISL on November 8.

2001
Rob Mise resigned as program director of Power 107 Calgary to succeed Eric Samuels as PD at CISL and CKZZ-FM. Samuels was named PD at CKFM and vice president of programming for Standard Radio in late December, 2000.

2007
On September 27, Astral Media Radio G.P. received CRTC approval to acquire the assets of the radio and TV undertakings owned by Standard Radio Ltd., subject to certain conditions.  The purchase included CISL and CKZZ-FM.

2008

In June, The Western Hockey League Vancouver Giants announced they had entered into a three-year agreement with Astral Media to broadcast all 72 regular season and playoff games on CISL.

As summer progressed, it was announced that veteran Vancouver broadcaster "Big Daddy" Dave McCormick had moved to CISL from rival CKBD, as that station prepared for a move to the FM band. It was further announced that other CKBD programs, including legendary bandleader Dal Richards' weekly show and the Fred & Gerry Home Improvement Show would also be moving to CISL. Then at 9 a.m. on November 10, CISL moved to "All Time Favourites" to fill the gap left by the move of CKBD to a AAA format on the FM band.

2009
On August 28, the CRTC renewed the transitional digital radio licence of CISL-DR-2.
