CBCNews.ca will livestream his remarks at 11 a.m. PT/2 p.m. ET.
Trudeau would also invite all the premiers to attend the United Nation's Climate Change Conference in Paris in what would be one of his first major international forays should he become prime minister. Within 90 days of the conference, a first ministers meeting on climate change would be held to come up with a plan that includes the creation of national emissions-reduction targets.
He also plans to fulfil a G20 pledge to phase out subsidies for the fossil fuel industry.
A Liberal government would invest $200 million each year to create sector-specific strategies that support innovation and clean technologies in the forestry, energy and agricultural sectors, and invest another $100 million to support clean technology companies.
In addition to climate change, Trudeau's environmental platform covers a range of promises from national parks to freshwater and oceans.
Ban on B.C.'s crude oil tanker traffic
In a bid to protect marine areas, the Liberal leader plans to formalize the moratorium on crude oil tanker traffic on British Columbia's North Coast. The House of Commons had adopted a NDP motion banning crude oil tanker traffic in 2010, but the resolution was non-binding. An unofficial moratorium had existed for decades prior to the NDP motion.
Trudeau has said previously that he does not support the Northern Gateway Pipeline and would not let it happen if his party assumes government.
He is expected to reannounce a pledge to work with the United States and Mexico to develop a North American clean energy and environmental agreement.
Ahead of Canada's 150th anniversary, Trudeau also said the Liberals would suspend admission fees to national parks in 2017. And beginning in 2018, admission to national parks would be free for children and adults who are new Canadian citizens.
The Liberals intend to reverse a number of cuts the Conservatives made to environmental programs, such as park budgets and ocean monitoring programs.
In May, the Conservatives announced that Canada would commit to reducing its greenhouse gas emissions by 30 per cent below 2005 levels by 2030.
Environment Minister Leona Aglukaqq also announced new rules to reduce methane emissions from the oil and gas sector, such as industrial leaks and gas flares, which makes up a significant portion of the industry's total emissions.
At the G7 summit earlier this month, Prime Minister Stephen Harper agreed to a commitment to deep cuts in carbon emissions by 2050 — with an eventual stop in the use of fossil fuels by the end of the century.
