Good directories have a long shelf-life as a reference source, so advertising in them is an excellent marketing opportunity. The OPCEA Directory will be distributed to key environmental professionals across Ontario, including those serving industries and municipalities. Reserve an ad in this directory and your company logo will run with your free listing, at no extra charge. Members will be sent an information package with details at the appropriate time.

OPCEA Celebrated 30 Years of Membership Directories in 2018

First published for distribution at the 1988 WEAO/OPCEA conference and tradeshow, OPCEA’s Membership Guide was the idea of Larry Madden of C&M Environmental. The first edition profiled OPCEA’s 60+ members and was a mere 24 largely black and white pages.

Since that time, the association has grown and the directory has followed suit.  The 2021 edition is colour and is “book bound” for added prestige and durability.

2018 marked the 30th edition of the OPCEA Membership Guide.
