(IRCC) began sending out invitations this week to potential sponsors through its Parents and Grandparents Program
In a March 19 update, Immigration, Refugees and Citizenship Canada (IRCC) announced that potential sponsors are now being selected at random and have 60 days (from the date of invitation) to submit a complete application. Sponsors who entered their names in the draw earlier this year are asked to check their email inboxes and spam folders for notifications from IRCC on whether they have been selected.
IRCC has provided this link https://gcs-ssc.cic.gc.ca/pgp/ for potentials sponsors to check if they have been invited to sponsor.
