Proportional representation may require Constitution change, Serge Joyal says

The federal Liberal government was warned Wednesday that its plans to overhaul Canada's electoral system could wind up plunging the country into constitutional wrangling a spectre Prime Minister Justin Trudeau has vowed to avoid.

SenatorSerge Joyal, an independent Liberal and acknowledged constitutional authority, said adopting some form of proportional representation could make majority governments less likely and require two or more parties to come together to form less stable minority or coalition governments.

That in turn could necessitate clarification of the Governor General's prerogative to decide which party leader becomes prime minister and, if a coalition collapses, when to dissolve Parliament.

And, Joyal noted, any change to the Governor General's powers would require a constitutional amendment approved by all 10 provinces.

"Anyone who will look into, seriously, to really implement proportional representation ... we have to review those things, those powers, because otherwise we will discover suddenly that we have created a nightmare and we won't know how to address it," Joyal told an open caucus meeting held by independent Liberal senators to hear from experts on electoral reform.

Joyal noted that an attempt to form a Liberal-NDP coalition government in 2008 led to a "crisis" in which then-prime minister Stephen Harper persuaded the Governor General to prorogue Parliament to avoid defeat of his minority Conservative government. The propriety of the Governor General's decision has been hotly debated ever since.

However, York University political science professor Dennis Pilon, who has researched electoral systems around the globe, said it's incorrect to assume that proportional representation (PR) would automatically lead to less stable governments. Indeed, he said Canada's current first-past-the-post (FPTP) electoral system produces more instability than PR systems.

Canada has produced "many more minority governments" than other Westminster-style Parliaments, Pilon said, in part because FPTP encourages political parties to be highly partisan and adversarial. By contrast, he said proportional systems encourage parties to be more collaborative.

Currently, the candidate who wins the most votes in a riding is elected, frequently with considerably less than 50 per cent of the vote. Majority governments are routinely elected with as little as 38 per cent of the national vote.

PR systems aim to ensure a party's share of the vote is more accurately reflected in its share of the seats in the legislature.

All-party committee to examine alternatives

Trudeau has promised that last fall's election will be the last conducted under FPTP. His government is preparing to create an all-party committee to examine alternatives, including PR and ranked ballots.

Democratic Institutions Minister Maryam Monsef said Wednesday that the government has no intention of reopening the Constitution, that whatever it does on electoral reform will be "within the constitutional framework."

The Liberal Senate caucus also heard from former chief electoral officer Jean-Pierre Kingsley, who said electoral reform is long overdue.

FPTP made sense early in Canada's history when there were only two main parties and one of them emerged from elections with more than 50 per cent of the vote, Kingsley said. But it no longer makes sense when there are five or more parties vying for election, all but guaranteeing none will gain true majority support.

The Conservatives are demanding that the Liberal government commit to holding a national referendum on any proposed electoral reform. But Kingsley, Pilon and Kelly Carmichael, executive director of Fair Vote Canada, all argued that there are other ways to consult Canadians.

Pilon said a referendum would be an "opportunity for mischief." And he warned politicians not to get caught up in "fake populism," noting that some groups, including the Conservative party, will try to orchestrate opposition to reform.

Liberal MP Mark Holland, Monsef's parliamentary secretary, said the all-party committee should do more than traditional, formal hearings and give all Canadians a chance to be heard.

"This needs to be historic engagement, it needs to be something the likes of which we've not seen before."

Nevertheless, Holland later said the government has not ruled out holding a referendum.
