"It's a form of political insurance policy that our leaders have chosen to go with," said Anthony Perl, a professor of urban studies and political science at SFU.
Next week, ballots for the plebiscite will be in the mail asking Metro Vancouver residents if they would pay half a per cent more PST to help invest in 10 years of transportation projects for the region.
Perl cites the example of the historic referendum of 2011, which saw the public reject the HST brought in by the Liberal government only two years before, despite much public opposition.
Based on that experience, the Liberals may have decided it would be safer to put the regional transportation tax to a vote, says Perl.
Premier Christy Clark first promised during the 2013 provincial election the government would hold a referendum on any new transit funding in Metro Vancouver, but the idea initially failed to gain the support of the region's mayors.
Since that time several mayors signed on, including Vancouver Mayor Gregor Robertson, and in Dec. 2014, the TransLink's Mayors' Council agreed to a plebiscite question, which was approved by the B.C. government.
'Better forms of leadership'
But Perl is not convinced a referendum is the best way to move the issue forward.
"There are better forms of leadership," said Perl. "Good leadership is something that creates a decision that people can live with for the future."
Perl points out that many major transportation projects, like the Port Mann bridge and the Massey Tunnel, are not put to a public vote.
Instead, the public relies on provincial leaders to make those decisions as elected representatives.
He says he would have preferred a public engagement process that would have prompted feedback from the public.
"It would have been much more deliberative, much more of a two-way street in terms of dialogue and communication," said Perl.
The upcoming referendum is a non-binding vote, meaning that provincial leaders could technically disregard the outcome. But Perl says that's unlikely.
"It would be hard to ignore the vote," said Perl. "Democracy is not easy to turn your back on once you've set it out."
