At Addimark, we know marketing isn’t about fluff or filler—it’s about results. Proudly Canadian-owned and operated, we’ve been delivering bold strategies and real outcomes since 2014, when Eric Harbottle founded the agency. Based in the thriving communities of Oshawa, Newmarket, Aurora, and Ajax-Pickering, we’re not just part of your neighbourhood—we’re part of your success story.
From sitting on Boards of Trade to rolling up our sleeves for charities like Their Opportunity and Easter Seals Ontario, we’re proud to contribute to causes that matter. Oh, and did we mention we’re the go-to marketing partner for the Oshawa Generals? Yeah, we’re that good.
When you work with Addimark, you get more than just a team of marketing experts. You get a partner who’s just as excited about your wins as you are (and maybe a little more).

Sure, we could brag about ourselves—but we’ll let our awards do the talking. From industry accolades to heartfelt community acknowledgments, we’ve racked up some pretty impressive wins. But our favorite recognition? The trust of our clients who keep coming back for more.


Every website, ad, and campaign we create starts with one thing: our team. We’re a group of marketing pros who know how to hustle, be creative and get results.
