Hey there, it's Stephen Dubner.

We recently published three-part series on immigration, mostly about the economics of immigration.

The first two episodes were focused on the U.S. and part

three on Canada which has recently turned the volume way up on immigration. They

now taken half a million new permanent residents a year in a country of around 40 million.

For that episode, we interviewed a variety of people, including Canada's immigration minister,

Mark Miller.

There is no doubt that we have made a conscious decision to be an open country and a country that

needs to grow. The reality is we don't have much of a choice. Miller's point was that Canada, like many high-income

countries, has an aging population and a need for more workers in many sectors of

the economy. We did ask Miller about the pressures that immigration

is putting on Canada, especially when it comes to affordable housing, access to health care,

and potential mismatches between immigrants and jobs.

But after we put out that episode, a lot of our Canadian listeners wrote in to say the

pressures were even greater than we knew, especially because Canada wasn't taking in just a half million new permanent

residence a year, but nearly 700,000 international students and 750,000 temporary foreign workers.

So we decided to revisit some of these questions, not with the Minister of Immigration, but with

his boss, the Prime Minister.

You can invite half a million people into your home every year if you're Canada.

Today on Freconomics Radio, my conversation with Canadian Prime Minister Justin Trudeau, and we go way beyond immigration.

We discuss whether to drill baby drill.

We talk about how Canada is reconciling its brutal history with its indigenous population.
