Brampton Mayor Patrick Brown jumped into the discussion via social media during a town hall meeting in Mississauga on Monday night about that city’s desire for independence from Peel Region, calling Mississauga’s numbers “flawed.”

Brown used one of the town hall Twitter hashtags to weigh in on the debate as it was happening.

For those attending the #SaugaTownHall please remember facts matter & the recent @regionofpeel Deloitte Report clearly states the numbers being used by #MissExit are flawed. In #Brampton, we love our neighbours in #Mississauga & #Caledon. Let’s stick to facts over misinformation! pic.twitter.com/sWwJ02QIxU — Patrick Brown (@patrickbrownont) April 9, 2019

Hundreds of residents gathered in council chambers at the Mississauga Civic Centre and on social media on April 8, for an update and to offer input regarding a March 20 Mississauga council motion in principle asking the provincial government to grant its exit from the region.

Crombie took the time during the meeting to respond to Brown's tweet.

"We do love our neighbours. That is not the issue. The issue is the future of #Mississauga. I will note that this slide in the Deloitte Report specifically says "General consideration for opposition." How is this not biased against #Mississauga?" she replied.

Shortly after Mississauga Mayor Bonnie Crombie announced the motion on March 20, Brown suggested Mississauga had its numbers wrong, and that it would owe its regional partner in Brampton and Caledon “hundreds of millions of dollars” to pay back shared regional monies used to build infrastructure in Mississauga.

Crombie called that allegation false. Shortly thereafter, at its March 28 meeting, Peel Region council voted in favour of making public a financial analysis by Deloitte Canada, which in part reviewed an earlier Mississauga staff report. The Deloitte report called parts of the data and some of the assumptions made in Mississauga’s report “flawed.”
