Canada's immigration system is broken, Conservative Leader Pierre Poilievre charged Tuesday, as he sidestepped questions about whether he would change current targets.

Appearing before reporters on Parliament Hill, Poilievre criticized Prime Minister Justin Trudeau's recent comments on housing and pledged to speed up entry for immigrants skilled in the building trades.

The federal government has set a target of welcoming 500,000 immigrants per year by 2025, although some worry about the pressure that could add to the country's housing crisis, driven by what experts agree is a supply shortage.

Ottawa has defended its ambitious target as necessary given the labour shortage and thousands of job vacancies that employers continue to experience since the COVID-19 pandemic, which triggered widespread lockdowns.

Poilievre slams the Liberal target as driven by Trudeau's "ideology," but he did not answer repeated questions about whether he would consider reducing the number.

He says a Conservative government would base its immigration policy on the needs of private-sector employers, the degree to which charities plan to support refugees and the desire for family reunification.

"I'll make sure we have housing and health care so that when people come here they have a roof overhead and care when they need it," he said Tuesday.

"I'll make sure that it's easier for employers to fill genuine job vacancies they cannot fill."

Poilievre's comments come as the Conservatives try to increase their support in newcomer communities in some of the country's largest cities and suburbs, selling the party as pro-immigration.

Besides appearing at numerous ethnic media roundtables, attending different cultural events and meeting with various business groups, Poilievre has championed cost-of-living issues in his outreach, from a lack of affordable housing to high food prices.

He has also honed in on concerns about the number of international students to die by suicide since the pandemic, with more relying on food banks given the cost of living.
