If you don't have the blog Blazing Cat Fur bookmarked and read it often I recommend you do so. From him I give you this link.
He has posted a video interview of Immigration Minister Jason Kenney by some talking head at the CBC. They discuss the revocation of citizenship of 1800 people who obtained it illegally but what struck me was when he was asked about immigration's role in addressing Canada's aging demographic. At the 5:10 mark he states "merely to maintain the current age ratio of younger to older people in our population through immigration would require more than quadrupling immigration levels to over 1 million a year." In other words the immigration system, aside from the total collapse of the border, cannot help Canada's aging demographic for the better. Immigration critics have been pointing this out for years and it's nice to hear a Minister of Immigration finally admit it. Note that it would take more that 1 million just to maintain the current ratio. How much more would be required just to reverse it?
Despite this Jason Kenney comes off as being weary about increasing levels and I can imagine why. Simply put, it is too damn expensive as is with diminishing returns with each new cohort; the immigration system costs more than it is worth with immigrants reaping the benefits at the expense of Canadians. For this reason it's financially unfeasible to up immigration targets high enough to reverse an aging demographic trend.
The solution I offer is to cut immigration dramatically to 60,000 or so and restrict it to young, preferably single, economic migrants, refugees aside. Family reunification would be non-existent. I'd revoke the Singh decision allowing for the dissolution of the IRB and have refugees vetted abroad. There are billions in tax dollars to be saved by doing so and with this money reinvest it into Canadian families as a means to up the birth rate. Right now Canadian tax dollars are being wasted on under-performing foreign born nationals.
Speaking of under-performing the link above introduces us to this story as well. I can't think of a better way to tackle Canada's skills shortage than with the importation of 100 Somali family members, can you?
