For the period covering its most recent financial year ending January 31, 2017, D2L has taken the following steps towards confirming that slavery and human trafficking does not exist in any of its supply chains:

Supply Chain Assessment

Due Diligence

Review of Procurement Procedures and Standard Contracting Terms

Raising Awareness

After this review, suppliers in high risk sectors without a published statement on modern slavery and human trafficking are being sent letters requesting confirmation that the supplier is taking steps to evaluate its business and supply chain and adopting measures to address modern slavery and human trafficking

To raise awareness in the organization, D2L has adopted and published a Policy on Modern Slavery and Human Trafficking and with which all employees must comply.

I don't find any specific sentence that states that D2L asks for contracts including clauses on forced labour. Also I don't see anything to prove that they prohibit the use of forced labour.

The only sentence they have concerning "forced labour" is :

"Overall, D2L has determined that the majority of its supply chain is low risk in terms of trafficking or forced labour measures."
