The campaign period for the referendum began on February 1, 2019, and applications opened for Yes and No campaigns to apply for public funding. During the campaign, Premier (and
Liberal leader)
Wade MacLauchlan did not take a public position on the vote. The leaders of all other parties, however, were on record as supporting a move to MMP. The leaders were also asked about their referendum positions in the
CBC Leaders' Debate. The form of MMP proposed would have had 18 district seats and nine island-wide top-up seats filled in compensatory fashion to address disproportionality of the district winners.
Open list PR was to be used to fill the top-up seats. The voter's marked preference on the Party Vote part of the ballot "would be used to determine each party's province-wide popular vote, and the number of votes each candidate on the party list receives will determine their ranking." The party share of popular vote would determine the party's share of total seats, and if the party did not win that many district seats, the party would receive top-up seats, if possible, with the party's top-up seats being allocated to the most-popular of the party's top-up candidates. A sample MMP ballot was issued during the campaign. ==Opinion polls==
