Canada is a nation built through generations of newcomers.
But now an asylum backlog coupled with a housing shortage means most Canadians are now questioning immigration levels.
Some are calling for a moratorium on immigration, though others say it's needed to ensure Canada's long term survival.

Hello, I'm Lucy Hawkins from the BBC World Service.
This is the global story.
Carrying a child for someone else could be seen as the ultimate selfless act.
It's also a booming global industry, generating billions of dollars every year.
I did it because I wanted to do it, because I wanted to create a family for someone who would otherwise not have one.
Surrogacy is growing in popularity.
But while demand is rising, more and more countries are taking steps to ban surrogacy completely.
Most recently Italy, where the far right government has passed a new law that makes surrogacy a universal crime, putting it on the same level as child abuse and human trafficking.
Nobody today is willing to accept the idea of two people of the same sex to create a family.
Today we're asking, is surrogacy exploitative or empowering?
And how easy is it to balance the desire of gay or infertile couples to become parents with the rights of the women who carry the children?
With me today is Sophia Batuzer, the BBC's gender and identity correspondent.
Good to have you with us.
Hi.
