The Vancouver-based publisher had announced in late October that it was filing for bankruptcy protection and was working to find an investor or purchaser for its assets.
The company will now remain under creditor protection until Jan. 4, 2015, and will be accepting investment or purchase offers until Nov. 26.
D&M, which includes Douglas & McIntyre and Greystone Books, says it plans to continue operations while it restructures.
It has said its subsidiary New Society Publishers Inc. is a separate legal entity, is not included in the bankruptcy filing and will continue business as usual.
D&M identifies itself as "Canada's pre-eminent independent publisher, with over forty years of success.''
It has published books that include the non-fiction work "Something Fierce'' by Carmen Aguirre, novels like Wayson Choy's "The Jade Peony'' and art books such as "The Art of Emily Carr.''
