OTTAWA — Prime Minister Justin Trudeau of Canada was selling, but it wasn’t clear that anyone was buying.

At a housing development in Ottawa on Wednesday afternoon, Mr. Trudeau pitched the wonders of his proposal to make home-buying easier, among a vast array of promises in a spending plan his government released this week.

Rod Allen, a retired resident of the development, said he liked some of Mr. Trudeau’s proposals. Still, he wants to hear more from Jody Wilson-Raybould, the former justice minister who has accused Mr. Trudeau and his top aides of improperly pressuring her on handling a criminal case against the Canadian multinational corporation SNC-Lavalin.

Among other things, he would like to know why she resigned from Mr. Trudeau’s cabinet.

Mr. Trudeau’s stop at the Cardinal Creek development on Ottawa’s eastern fringes was the first on what will be a cross-Canada trip to sell his spending plan, and to make his case for re-election this fall.
