I am not too sure however, following are my views:
Usually employers don't ask for PR card except SIN Card.
PR card holders/citizens have sin card # starting with 7
However, immigration documents are required for the employers when sin# starts with 9.
Here is a helpful link:

If an employer still asks for the immigration document then, I can't say much how or why they ask for it.
1. SIN initial digit shows where the person applied from.
The first digit of a SIN usually identifies the province in which it was registered, as listed below. However, the government has found it necessary in the past to supply certain regions with SIN numbers assigned to other regions.[citation needed]
1: Nova Scotia, New Brunswick, Prince Edward Island, and Newfoundland and Labrador
2–3: Quebec
4–5: Ontario (excluding Northwestern Ontario), and overseas forces
6: Northwestern Ontario, Manitoba, Saskatchewan, Alberta, Northwest Territories, and Nunavut
7: British Columbia and Yukon
8: Not used
9: Temporary resident
2. The employer may ask for the PR card, as the onus is on the employer to determine if the person is eligible to work in Canada.
