The federal minister of environment and climate change says she continues to promote Prime Minister Justin Trudeau.

Catherine McKenna reiterated her support for Trudeau during a stop in Windsor on Tuesday.

McKenna's visit was to highlight the government's climate action incentive payment, where homeowners qualify for a rebate.

But McKenna could not avoid questions about her confidence in the Prime Minister after the resignation of two female cabinet ministers over the SNC Lavalin scandal.

Trudeau has been facing calls to resign after former attorney general Jody Wilson-Raybould testified at the House Justice committee last week that she faced high-level "veiled threats" and "sustained" political interference from nearly a dozen people to try to get her to instruct federal prosecutors to drop the criminal prosecution of the Quebec construction and engineering company that is facing bribery and corruption charges over business dealings in Libya.

On Monday, Jane Philpott resigned from cabinet as Treasury Board President, saying that she has lost confidence in the way the government is handling the scandal.

But McKenna says she has absolute confidence in Trudeau.

"I have full confidence in the prime minister and I think look, you have strong women who will have different perspectives on this issue," says McKenna.

McKenna also believes the government must remain focused on its agenda.

“I think it's really important that Canadians have faith in our political institutions but of course we still need to move forward on the agenda we were elected on," says McKenna. “Our focus is how to make life more affordable and of course tackle big issues like climate change.”

The minister toured a Windsor home on Tuesday to see an energy efficient furnace and water heater and promoted the government's climate action incentive payment.

The payment allows people in Saskatchewan, Manitoba, New Brunswick and Ontario to claim a benefit with your income tax return. McKenna says a family of four in Ontario can claim $307.

Homeowners Dino and Lisa Belluzzo were eager to welcome the minister, but disappointed all the talk was about the 'heat' on the Liberals and not their efficient furnace.

McKenna also spoke about climate change to students at a town hall meeting at the University of Windsor and met privately with Windsor Mayor Drew Dilkens.​
