Essentially, C-428 would enable immigrants from India, China and other countries to claim OAS after three years of residency (as opposed to the current 10). There is very little in the news about it, and politicians--even the Conservatives--are being very quiet about it.
The problem with this bill (and a similar one, introduced by Conservative Gurmant Grewal, before the last election) is that it would spell actuarial armageddon for the Old Age Security system. The reason for the 'unfairness', with respect to Indian, Chinese and other immigrant retirees is twofold. First of all, developed countries (U.S., UK) have reciprocity agreements with Canada, over pensions. Secondly, the flow of retirees between Canada and India, China, &c. is essentailly one-way. There is no way OAS can survive the spike in claims that would result from this bill.
Obviously, this is a sop to Dhalla's constituents. I suspect the Conservatives and NDP aren't saying anything, lest they annoy South Asian and Chinese voters. However, CARP (Canadian Association of Retired Persons) has vocally opposed it. I strongly urge anyone reading this to do the same--contact your MP, whatever his/her party affiliation. This isn't about 'fairness', but the survival of one of Canada's most important social programmes. Here, Milton Friedman's quip about having to choose between (mass) immigration and the welfare state is certainly true, here.
