This is from the published bill. The Library of Parliament often publishes better independent summaries.
This enactment enacts the Modern Slavery Act, which imposes an obligation on certain entities to report on the measures taken
to prevent and reduce the risk that forced labour or child labour
is used at any step in the production of goods in Canada or elsewhere by the entity or in the production of goods imported into Canada. The Act
provides for an inspection regime and gives the Minister the
power to require an entity to provide certain information.
This enactment also amends the Customs Tariff to allow for a
prohibition on the importation of goods manufactured or produced,
in whole or in part, by forced labour or child labour.
