Season three starts three months after the end of season two when the guys left for the North Pole. 
"The Big Bang Theory" started off quietly in Canada, but managed to garner major success later on in further seasons.
"The Big Bang Theory" is telecast throughout Canada via the CTV Television Network in simultaneous substitution with cross-border CBS affiliates.
Now immensely popular in Canada, "The Big Bang Theory" is also rerun daily on the Canadian cable channel The Comedy Network.
The season 4 premiere garnered an estimated 3.1 million viewers across Canada.
This is the largest audience for a sitcom since the series finale of "Friends".
"The Big Bang Theory" has pulled ahead and has now become the most-watched entertainment television show in Canada. 
The seventh season of the American sitcom "The Big Bang Theory" premiered on CBS on September 26, 2013 with two episodes back-to-back.
On March 12, 2014, "The Big Bang Theory" was renewed for an additional three years, extending it through the 2016–17 season for a total of ten seasons.
Production for the seventh season began on August 14, 2013. 
"The Big Bang Theory" has been highly rated since its premiere.
When the third season premiered on September 21, 2009, "The Big Bang Theory" ranked as CBS's highest-rated show of that evening in the adults 18–49 demographic (4.6/10) along with a then-series-high 12.83 million viewers.
After the first three seasons aired at different times on Monday nights, CBS moved the show to Thursdays at 8:00 ET for the 2010–2011 schedule, to be in direct competition with NBC's Comedy Block.
During its fourth season, it became television's highest rated comedy, just barely beating out eight-year champ "Two and a Half Men".
However, in the age 18–49 demographic (the show's target age range), it was the second highest rated comedy, behind ABC's "Modern Family".
The fifth season opened with viewing figures of over 14 million.
The sixth season boasts some of the highest-rated episodes for the show so far, with a then-new series high set with "The Bakersfield Expedition" (Season 6, Episode 13), with 20 million viewers, a first for the series, which along with "NCIS", made CBS the first network to have two scripted series reach that large an audience in the same week since 2007.
In the sixth season, the show became the highest rated and viewed scripted show in the 18–49 demographic, trailing only "NBC's Sunday Night Football" coverage, and was third in total viewers, trailing "NCIS" and "Sunday Night Football".
Season seven of the show opened strong, continuing the success gained in season six, with the second episode of the premiere, "The Deception Verification", setting the new series high in viewers with 20.44 million.
Showrunner Steve Molaro, who took over from Bill Prady with the sixth season, credits some of the show's success to the sitcom's exposure in off-network syndication, particularly on TBS, while Michael Schneider of "TV Guide" attributes it to the timeslot move two seasons earlier.
Chuck Lorre and CBS Entertainment president Nina Tassler also credit the success to the influence of Molaro, in particular the deepening exploration of the firmly established regular characters and their interpersonal relationships, such as the on-again, off-again relationship between Leonard and Penny.
Throughout much of the 2012–13 season, "The Big Bang Theory" placed first in all of syndication ratings, receiving formidable competition from only "Judge Judy" and "Wheel of Fortune" (first-run syndication programs).
By the end of the 2012–13 television season, "The Big Bang Theory" had dethroned "Judge Judy" as the ratings leader in all of syndicated programming with 7.1, "Judy" descending to second place for that season with a 7.0.
