When you enter a consumer proposal, any court-related fees will be regulated under the Bankruptcy and Insolvency Act. You may want to pay for legal representation too. On the other hand, a for-profit credit counsellor can charge their own prices to administer a DMP. Service fees are regulated in some provinces and territories but could include:
Initial setup fee
Monthly maintenance fee
Membership fee
Application fee
Upfront/creditor fee
Even if you hire a non-profit credit counsellor, you could get charged indirect fees, since non-profit organizations are subject to the same provincial and territorial regulations.
