Nanos Research Chairman Nik Nanos said the final poll, released at 10 p.m. on Oct. 18 , was a good indicator of the final election results.
"Everything was right, it was pretty much perfect," he told CTV News Channel on Tuesday.
The Liberals, Nanos said, did above-average in converting into seats in Atlantic Canada, where all 32 seats went to the Liberals. But B.C., where 17 seats went to the Liberals, still played an important role in choosing a national government.
"Justin Trudeau has made the breakthrough his father never did. He's basically won a seat in every single province in the country, and the territories," Nanos said.
Still, Nanos says, it’s not Trudeaumania. “I think it's very important for the new prime minister to remember that," Nanos told CTV News Channel’s Marcia MacMillan in an interview Tuesday morning.
"On the preferred prime minister front, he only had a six-point advantage. Yes people like Justin Trudeau, comparatively, more than Stephen Harper, but we have to remember the Liberals were seen as agents of change -- now they have to deliver on change. "
*Note on methodology:
The daily tracking figures are based on a three-day rolling sample composed of 2,400 interviews. To update the tracking a new day of interviewing is added and the oldest day dropped. For Sunday Oct. 18’s one-day numbers, the margin of error for 722 decided voters was ±3.7 percentage points, 19 times out of 20.
