Recently announced Canadian Prime Minister 43-year-old Justin Trudeau is already setting a new tone in his leadership, speaking on Tuesday the changes and improvements he is bound to make in his seat in the office.

"To this country's friends around the world, I want to say this: Many of you have worried Canada has lost its compassionate and constructive voice in the world over the past 10 years. I have a simple message for you: We're back," the son of former Prime Minister Pierre Trudeau said at a rally in Ottawa last Tuesday, as quoted by The Wall Street Journal.

Trudeau, with his Liberal platform, is promising a new kind of leadership compared to the 10-year term of former Conservative departing Prime Minister Stephen Harper.  Whether in playing up wedge issues or Canada's foreign affairs, Trudeau revealed to be setting new grounds.

The Wall Street Journal reports that Trudeau will be present at the climate-change conference in Paris in his goal to gain new understanding regarding environmental issues. The Guardian even revealed that Trudeau has already made a 90-day timeline for a climate change policy after the summit in Paris this November.

Not only that, Trudeau will also be looking at policy changes in the economy. "The Liberal willingness to use fiscal policy to stimulate the economy would be a positive for current economic conditions, where growth is likely to stay below trend for some time," Nomura Securities said as quoted by the Wall Street Journal in a note to clients.

The newly seated Prime Minister also previously shared his concern with the indigenous people during his campaign. "We will build a renewed relationship with indigenous peoples on a nation-to-nation basis," Trudeau said per The Guardian. "That will include, for example, a national public inquiry into missing and murdered indigenous women and girls. It will include $2.6bn over four years for First Nations education."

Trudeau's win in the 11-week election period ended Monday as the Liberals won 184 of the 338 electoral districts up for grabs in the Canadian legislature, which is a total of 39 percent of the popular vote, according to The Wall Street Journal.

The newly-elect even previously described the significance of the election period with him as he struggled to be the top candidate from only being third in previous polls. "If there's one thing that recent history in Canada has shown it's that campaigns really matter. And there's a tremendous volatility among voters who are just looking for the right alternative," Trudeau previously told The Guardian.

However, Penny Collenette, an adviser to former Liberal Prime Minister Jean Chretien, feels that the work is only just beginning for the newly elected Prime Minister. "The job of being prime minister is night and day compared to campaigning," Collenette said via the Wall Street Journal.
