The hearing gets underway on Parliament Hill at 10 a.m. ET.
In a landmark ruling last December, the Supreme Court concluded that several key provisions of the existing prostitution laws were unconstitutional, and gave the government one year to come up with a new legal framework.
In May, MacKay introduced legislation to create what he has referred to as a "Made in Canada" law, which borrows heavily from the so-called Nordic model by focusing legal sanctions on the buyers, rather than the sellers of sex.
Earlier this summer, the House justice committee heard from sex workers, anti-trafficking experts, academics and advocacy groups from both sides of the debate over legalizing prostitution.
After three days of hearings, MPs voted to amend the bill to narrow the proposed restrictions on "public communication" to cover only areas in the vicinity of schoolyards, daycares and playgrounds.
That change — and, specifically, whether it goes far enough to address the concern that the new rules will do little to protect the safety and security of sex workers — will likely be one of the main issues up for discussion as the Senate committee begins its review of the bill.
