No.
Bill C-20 amends the Constitution Act of 1967, modifying the rules for calculating the province's representation in the House. The amendment attempts to exempt the Province of Quebec from the proposed rules.
The House of Commons Procedure and Practice, second edition, states, on page 766:
An amendment to a bill that was referred to a committee after second reading is out of order if it is beyond the scope and principle of the bill.
In the opinion of the chair, the introduction of this exemption for the rules for Quebec is a new concept that's beyond the scope of this bill.
