Mississauga: 65% Back Subway; Transit Priorities Split
Sixty-five per cent support a subway extension, but residents split 45% to 44% on subway versus all-day, two-way Milton GO service. Confidence combines very and somewhat confident.
October 7, 2026 (Toronto, ON) - A new Liaison Strategies Mississauga survey finds 65% of residents support extending subway service to downtown Mississauga near Square One. Asked which would be the better transit investment, 45% choose the subway extension and 44% choose all-day, two-way GO service on the Milton line. The findings follow Bonnie Crombie's September 24 proposal to extend Toronto's Line 2 into Mississauga.
Liaison surveyed a random sample of 1,000 Mississauga residents from October 2 to October 4, 2026, using Interactive Voice Recording (IVR) technology. Participants were reached through random digit dialling (RDD) across both landline and cellular phone networks. The resulting data was weighted to match targets based on the 2021 Census. For the total sample, the margin of error is +/- 3.1 percentage points, 19 times out of 20, and is higher for subsamples. Results may not add to 100% due to rounding.

David Valentin, Principal at Liaison Strategies, said:
"Crombie's subway proposal has a substantial audience. Sixty-five per cent support an extension near Square One, 20% oppose it, and 15% are unsure."
"The more competitive question is what should take priority. Forty-five per cent select the subway as the better investment, while 44% select all-day, two-way Milton GO service and 11% are unsure. Residents favour better transit, but there is no clear winner when these two options are put side by side."
"Crombie's platform also proposes GO improvements, so the poll should not be read as forcing candidates into mutually exclusive positions. It measures which investment residents prefer when asked to choose."
"Among respondents who initially chose Parrish, 56% prefer GO and 34% prefer the subway. Among those who initially chose Crombie, 56% prefer the subway and 33% prefer GO. Yet 60% of Parrish supporters also support a subway extension. Residents can like a project without putting it first."
"Combining very and somewhat confident, 19% are confident the subway extension will be built: 4% are very confident and 15% somewhat confident. Sixty-one per cent are not very or not at all confident, and 20% are unsure. This is a campaign proposal being promoted by Crombie, with its future still dependent on the election and decisions by other governments. Uncertainty about delivery should not be confused with opposition to the proposal."
"On all-day, two-way Milton GO service, 38% are very or somewhat confident it will be introduced, combining 13% very confident and 25% somewhat confident. Forty-three per cent are not very or not at all confident, and 19% are unsure. Confidence is higher for GO, but these figures do not tell us why residents expect one project to happen more than the other."
"The subway attracts majority support across the main candidate groups: 76% among those who initially chose Crombie, 70% among Tedjo supporters, 62% among Damerla supporters, and 60% among Parrish supporters. It is also supported by 58% of initially undecided respondents. The proposal has appeal beyond the candidate promoting it."
"The useful distinction is between support, priority and confidence. Most residents support a subway extension. They are evenly divided on whether it is a better investment than expanded GO service. Whether either project gets built is a separate question."
