Very happy that our Team @LiaisonCanada polling performed very well yesterday.

As of now, barring any changes from recounts, etc., Liaison is the most accurate pollster of the Ontario election #onpoli

Breaking: @MayorOliviaChow is running for re-election come Oct. 26. Monday’s confirmation ends months of speculation and sets up what’s expected to be a bitter contest with @BradMBradford, who declared last year he’s running for mayor. https://t.co/SPuhgQEGk3 via @TorontoStar

Sad to hear this, Howard was a great guy, very generous with his time, and my city councillor growing up.

May his memory be a blessing.

Howard Moscoe, one of Toronto's most colourful city councillors - famed as a canny progressive strategist and twinkle-eyed trickster while TTC chair, taxi reformer and Mel Lastman nemesis - has died at age 86 https://t.co/V0I3ZOp8Le

When I was at Mainstreet there actually was a semi-serious discussion with a producer about a reality TV show lmao

[Bryan Breguet @Prominent_Bryan]

We seriously need a reality TV show with Canadian pollsters

[David Valentin @davidvalentin]

This is an impressive project! #cdnpoli
