Here's a look at five Canadian storylines to watch at the upcoming Rio Olympics:

BIG TRACK ATTACK

The national track and field team made a statement at the world championship last year in Beijing. The athletes are hoping for even bigger things at the Summer Games.

Derek Drouin won world gold in the high jump and Shawn Barber finished first in the pole vault as Canada reached the podium eight times.

They will anchor a strong Canadian contingent in Rio that includes Andre De Grasse, who could challenge defending champion Usain Bolt in the men's 100 metres.

NEW WORLD ORDER

The Canadian Olympic Committee made organizational changes after allegations of sexual harassment were levelled at former president Marcel Aubut last year.

Aubut resigned in October and two executives and a manager were fired, with former Olympic rower Tricia Smith taking over as president.

In addition, Jean-Luc Brassard recently stepped aside as Canadian team chef de mission, with Curt Harnett taking over.

The changes all came less than a year out from Rio but the COC has said it remains confident the athletes will be ready for the Games.

SWAN SONGS

This could be the final Summer Games for a number of prominent Canadian athletes.

Swimmer Ryan Cochrane, who made his senior international debut in 2006, is set to compete at his third Olympics. It's a virtual certainty that this will be his final Games.

It will also likely be the Olympic swan song for two big-name members of the canoe-kayak team.

Kayaker Adam van Koeverden, who won gold in 2004 at Athens, is set to compete at the Games for the fourth time while canoeist Mark Oldershaw will make his third Olympic appearance.

TEAM EFFORT

There will be some fresh faces for Canada in Rio as the country has qualified five teams for the Summer Games.

The men's volleyball team is returning to the Olympics for the first time in 24 years.

The women's soccer team has also qualified for the Games, along with the women's basketball, women's rugby and men's field hockey teams.

It's the most team entries since Canada entered five teams at the 2008 Beijing Games.

PODIUM POWER

Golf and rugby sevens have been added to the Olympic program and that could mean medals for Canada.

Teen phenom Brooke Henderson of Smiths Falls, Ont., is among the top-ranked female golfers in the world and has already won a major this year. She's a serious contender for the podium as golf returns to the Summer Games for the first time since 1904.

While Canada's men's rugby sevens team failed to qualify, the women's squad is likely the country's best bet for a medal in a team event.

Canada has a history of performing well in new Olympic events. Remember triathlete Simon Whitfield at the 2000 Sydney Games?
