From taxes to a possible solution on secondary suites, plus a contentious election campaign that got personal, Global News catches up with Mayor Naheed Nenshi as 2017 comes to a close.

The head of Mainstreet Research has denied reports that he is considering legal action against pollster Brian Singh, on the same day the company released the results of a review looking into what he called a “catastrophic polling failure” in the Calgary election.

Five new trustees and two returning trustees were sworn in on Friday.

A swearing-in ceremony was held Monday for Calgary city councillors elected in last Monday’s 2017 municipal election.

"I imagine by the end of Monday all of those signs will be gone, if they're still there after that then obviously we can take some further action."

Mainstreet president Quito Maggi said he watched with “utter shock and embarrassment as our final prediction in the municipal election was completely and totally wrong.”

Pollster Janet Brown said the late arrival in the Calgary race of political novice Bill Smith was initially done as a test for the provincial vote in 2019.
