This is the argument that the British government made years ago...they just didn't tell any of the British people their plans.

Canada to admit nearly 1 million immigrants over next 3 years
Canada will welcome nearly one million immigrants over the next three years, according to the multi-year strategy tabled by the Liberal government today in what it calls "the most ambitious immigration levels in recent history."
The number of economic migrants, family reunifications and refugees will climb to 310,000 in 2018, up from 300,000 this year. That number will rise to 330,000 in 2019 then 340,000 in 2020.
The targets for economic migrants, refugees and family members was tabled in the House of Commons Wednesday afternoon.
Hussen said the new targets will bring Canada's immigration to nearly one per cent of the population by 2020, which will help offset an aging demographic. He called it a historic and responsible plan and "the most ambitious" in recent history.
"Our government believes that newcomers play a vital role in our society," Hussen said. "Five million Canadians are set to retire by 2035 and we have fewer people working to support seniors and retirees."

In 1971 there were 6.6 people of working age for each senior, Hussen said, but by 2012 that ratio had gone to 4.2 to 1 and projections show it will be at 2 to 1 by 2036, when almost 100 per cent of population growth will be a result of immigration; it stands at about 75 per cent today.
