Comedian Rick Mercer is dedicating a couple of segments on his TV show, the Rick Mercer Report, to highlight the bay on Tuesday night.
Mercer is also one of several celebrities and politicians helping to promote the cause by getting muddy in a web-based video posted Tuesday by VoteMyFundy.com.
The bay is one of 28 finalists in the worldwide contest to name 7 new natural wonders.
It is Canada's only remaining entrant in the contest.
"The whole point of this episode is to push the VoteMyFundy initiative. And I wanted to make it look good," said Mercer, who recently spent two days on the Bay of Fundy taping the segments.
The show features Mercer going whale watching near St. Andrews with Fredericton native and opera singer Measha Brueggergosman, who grew up near the bay.
"I think people are going to be gob-smacked at the whales," said Mercer.
Mercer also hopes riding the rapids on the Reversing Falls Jet Boat in Saint John with New Brunswick Premier David Alward will bring a wave of support for the bay.
"Certainly seemed like (Alward) was going to do whatever he needed to do to promote the Bay of Fundy in this initiative... although he did say he wouldn't get naked and jump in the Bay with me," said Mercer.
"Although I will go on record to say I didn't make the offer."
MP Bob Rae famously jumped in a lake naked with Mercer on a previous episode.
Competition getting dirty
In the VoteMyFundy promotional video, Mercer, Brueggergosman and Alward are among the several celebrity supporters sporting Bay of Fundy mud on their hands and faces.
The video opens with Alward and Nova Scotia Premier Darrell Dexter, representing both sides of the bay and urging Canadians to vote for the bay.
Other participants include singer-songwriters Jann Arden and Joel Plaskett, Canadian rapper Maestro Fresh Wes, and the anchors of Canada AM.
Subsequent videos will be posted, featuring songwriter and recording artist David Myles, the cast of This Hour Has 22 Minutes, French singer Jean-François Breau, Home and Garden Television (HGTV) host Scott McGillivray, actor K.C. Collins and Cape Breton singer Mary Jane Lamond with fiddler Wendy MacIsaac.
Canadians are also being encouraged to create and upload their own video explaining why they voted for Fundy on the website or on the Bay of Fundy Facebook page.
The New 7 Wonders campaign, led by Swiss adventurer Bernard Weber, aims to support, preserve and restore monuments and natural sites.
More than 440 sites entered the competition.
The Bay of Fundy is now competing with other major tourist attractions such as the Dead Sea, the Grand Canyon, the Great Barrier Reef and the Amazon rainforest.
The winners will be declared on Nov. 11.
The bay, which stretches between New Brunswick and Nova Scotia, has the highest tides in the world at 53 feet.
It also has the potential to become one of the world's greatest producers of tidal energy, hosts more than 12 species of whales during their summer and fall feedings, and its marine biodiversity has been compared to the Amazon Rainforest.
Canadians can continue to support Bay of Fundy's quest to become one of the New7Wonders of Nature by voting for the Bay of Fundy online for free at www.votemyfundy.com or through the New7Wonders of Nature Facebook page.
They can also vote from their mobile phones by texting FUNDY to 77077 ($0.25 per text vote).
The Rick Mercer Report airs at 8 p.m. on CBC Television.
