Canada has never had an open-ended immigration levels plan. We have managed and established priorities between immigration categories for many decades.
What happened in the parent and grandparent program was that for many years we accepted far more applications than space allocated under the levels plan. So we were taking 35,000 to 40,000 person applications per year and allotting level space of 15,000 to 20,000. I can't anticipate what the future levels will be in the parent and grandparent program, but last year, and again this year, the government set the levels plan at 25,000, which is the highest in many years.
