Under Canada’s two-tier Social Security system, a person may receive an Old-Age Security
(OAS) benefit plus a Canada Pension Plan (CPP) or Quebec Pension Plan (QPP) benefit.
(It is not possible to receive both CPP and QPP.) The CDN-USA 1 is used if the applicant
is filing for OAS and/or CPP benefits. The QUE/USA-1 is used if the applicant is filing
for QPP benefits.
The worker’s last place of residence in Canada determines whether the CPP or QPP applies.
Applicants should apply for QPP benefits using the QUE/USA-1 when the worker’s last
place of residence in Canada was Quebec. Applicants should apply for CPP benefits
using the CDN-USA 1 when the worker last resided in any other part of Canada. If the
applicant is filing for both OAS and CPP benefits, only one application Form CDN-USA
1 is used.
