===End of all-sports era and transition to traffic information===
On September 2, 2011, at exactly 10&nbsp;am, CKAC dropped its all-sports format. A recorded announcement from Cogeco vice president Richard Lachance was played, announcing a new [[travelers' information station|traffic information]] format that would launch at 4:30&nbsp;am on September 6. Branded as ''Radio Circulation 730'', the new format is being subsidized by the Quebec government, and will feature round-the-clock traffic updates from around Montreal, and it has become Canada's first radio station entirely dedicated to traffic and weather (because AM730 adds some Vancouver's news from CKNW in between). This relaunch superseded an application Cogeco had filed with the CRTC earlier in the year to reactivate the former [[CINF]] (Info 690) transmitter for a similar format (while maintaining all-sports on CKAC). Unlike Cogeco's original plans for 690&nbsp;kHz, CKAC's traffic radio service operates 24 hours a day, with live announcers on the air between 6:00 and 1:00 (non-holiday weekdays are 90' earlier). Pre-recorded announcements detailing overnight road closures and detours are played when live announcers are not on the air.

Effective September 6, some of CKAC's sports programming and airstaff have moved over to CHMP, along with [[Montreal Canadiens]] and [[Montreal Alouettes]] broadcasts.<ref>[http://blog.fagstein.com/2011/09/02/ckac-sports-ends/ Government pays for Cogeco to shut down CKAC Sports, September 2, 2011]</ref><ref>[http://www.marketwire.com/press-release/on-september-6-ckac-becomes-radio-circulation-730-montreals-first-dedicated-traffic-1556827.htm On September 6, CKAC Becomes Radio Circulation 730, Montreal's First Dedicated Traffic Radio Station, September 2, 2011]</ref>

After playing a wide variety of continuous music over Labour Day weekend, Radio Circulation 730 made its debut at 4:30&nbsp;am on September 6, as announced. The first announcer heard on the air was Michel Millard.

Alongside the original (and ultimately abandoned) application to place traffic information on 690, Cogeco also planned on an English-language traffic radio service for 940 previously used by [[CINW]].<ref>[http://www.crtc.gc.ca/eng/archive/2011/2011-571.htm Broadcasting Notice of Consultation CRTC 2011-571, September 7, 2011].</ref> However, that frequency was awarded instead to Paul Tietolman, for a francophone news-talk radio service.<ref>[http://www.crtc.gc.ca/eng/archive/2011/2011-721.htm Broadcasting Decision CRTC 2011-721, November 21, 2011].</ref>
