Checking-in: Wren Kauffman, Justin Trudeau and the Northern Gateway pipeline

Justin Trudeau: On Tuesday, we heard from Liberal Leader Justin Trudeau about his wish to unseat Prime Minister Stephen Harper in the next federal election, and what he'd do if he gets the chance.

After the interview aired, some of our listeners wrote in to tell us what questions they would have asked Mr. Trudeau.

Ursula Lowrey from Nelson, B.C., e-mailed us this:

What a missed opportunity to ask Mr. Trudeau about the most important topic of our age: climate change! The Harper government has set Canada back 20 years in coping with this problem. What would a Liberal government do differently?

Susan Walp of Cranbrook, B.C. sent us this thought:

It's good that Mr. Trudeau wants to make this world a better place for his kids. However, the person who gets my vote for prime minister will, I hope, want to make this world a better place for everybody's kids -- those at Attawapiskat, those whose ancestors are from Africville, and those from other nations all over the world.

World Cup: Less than a week into the World Cup, some coaches, fans, and commentators were so fed up with what they believe were bad calls by referees, they demanded FIFA start using video replays.

We asked if it was time to introduce replay technology to give referees another set of eyes.

T. Klass tweeted:

Better the right call than the 'fast' call, #horribleofficiating

But Lucien Atchale balked at the idea of more technology in the sport, tweeting:

Everyone could not afford it. No-one wants soccer games to turn exclusive for those who can afford technology.

Jonathan Pearson of Vancouver says that instant replay is good for other sports as well:

The addition of replay challenges in baseball this year has made a huge improvement in the game. I don't have the statistics, but I think that umpire/player and umpire/manager conflicts and the resulting ejections are down dramatically...

Wren Kauffman: In September, we brought you an interview that moved many listeners. Wren Kauffman is a twelve year old boy who is transgender. We spoke with Wren and his family as he was embarking on a new school year as a grade seven student.

Now, as the school year comes to an end, we invited the family back to share an update on Wren's fight to get his birth certificate switched from female to male.

It feels good because now I know other people aren't going to have such a difficult time.Wren Kauffman

Wren Kauffman, his mother Wen, and little sister Avy joined us from Edmonton.

Northern Gateway: On Tuesday, the federal government announced its approval of the Northern Gateway Pipeline, and the 209 conditions attached to that approval. The next morning, we spoke with a number of key people directly affected by that decision...both those in favour and those opposed.

After that story aired, many of you wrote in with strong feelings about this story.

Jezabel Diablo ‏tweeted:

My standard of living includes clean air and water. #Enbridge no means no.

Paul Heglund posted this on Facebook:

The pipeline is a much needed development. Sadly it will never happen, a result of too much misplaced, misguided and opportunistic opposition.

Animal abuse: And finally, last Wednesday, we spoke about animal cruelty after the animal rights group Mercy for Animals Canada released an undercover video, appearing to show workers at Chilliwack Cattle Sales Farm abusing cattle with chains, rakes and canes.

In response to the video and the public outrage, dairy producer Saputo announced the company would no longer accept milk from Chilliwack farms. And the B.C. Milk Marketing Board, a provincial regulatory board that controls the production, marketing, and transportation of milk, released this statement earlier this week:

The Board has received requests from processors that milk orders do not include milk deliveries from Chilliwack Cattle Sales until the additional independent audits have been completed. The Board will act in accordance with processor requests and due to lack of market, the milk will be destroyed.
