This second weekly snapshot tracked tweets from Wednesday, May 11, 2022 at 12:00 p.m. ET to Wednesday, May 18, 2022 at 11:59 a.m. ET.


This Snapshot was generated on May 19, 2022. The data presented is accurate at the time of posting, however as the machine learning model is updated, the toxicity measurements presented here may become outdated. Our Ontario Election Snapshot provides analysis that is consistent across the election period.

SAMbot uses a natural language processing machine learning model. This means that SAMbot is trained and tested on millions of data points so it can understand whether tweets can be considered toxic, harmful, or insulting. Machine learning algorithms are regularly updated as they learn and have access to improved data. Updates to the third-party algorithms SAMbot uses to measure toxicity can lead to slight discrepancies in toxicity measurements across different Snapshots. Our Ontario Election Snapshot analyzes all of the data collected throughout the election period using the same model in order to have consistency in measurement.

Key Findings

  • The second and final leaders debate was held on Monday, May 16, 2022 at 6:30pm. While SAMbot recorded a high volume of tweets during and after the debate, less than 7% of all tweets between 12:00 pm ET and 11:59 pm ET were toxic. Discussions on Twitter surrounding the leaders debate were significantly more positive or neutral in sentiment compared to the rest of the period.
  • Ontario PC Party leader Doug Ford received the most toxicity again this week, receiving over twice as many toxic tweets than Liberal Party of Ontario leader Steven Del Duca, who received the second highest volume of toxic tweets.
  • Party leaders Andrea Horwath of the Ontario NDP and Mike Schreiner of the Green Party of Ontario received an increase in total tweets this week, but both candidates didn’t see an increase in the rate of toxicity received compared to last week.

News from the campaign trail

  • There continues to be significant conversation on Twitter surrounding the race in the Nepean riding. Both Ontario PC Party candidate Lisa MacLeod and Liberal Party of Ontario Candidate Tyler Watt remain on SAMbot’s “top ten candidates” list for the second week in a row.
  • Mitzie Hunter, Liberal candidate for Scarborough—Guildwood and former Liberal Minister of Education, spurred online discussion this week after her announcement on Sunday, May 15, 2022. She criticized the PC Party of Ontario and its leader, Doug Ford, for what she referred to as “the Conservative gravy train at Queen’s Park.” She revealed 16 of the 41 PC Party of Ontario candidates defeated in the 2018 Ontario election were given roles within the Ontario public service shortly after losing their respective elections.
    • Hunter has received a significantly higher amount of identity attacks compared to the candidate average this week. Based on data collected thus far, approximately 3.4% of all tweets directed at tracked candidates are identity attacks, whereas for Hunter, 8.1% of tweets directed at her this week were identity attacks.
  • Green Party of Ontario leader Mike Schreiner saw an increase in tweets this week on the night of the leaders debate. Despite receiving more than 2.5 times the amount of tweets this week compared to last, Schreiner received a lower rate of toxicity; 8.9% of all tweets received by Schreiner last week were likely toxic, while this week only 4.2% of all tweets this week were likely toxic.
