In a statement posted on Nelson's website, they write that "Independent studies" conclude that their application to blast 124 additional acres in Burlington's Mt. Nemo would "have no adverse environmental impact."


CORE Burlington begs to differ.


We're On A Salamander Rescue Mission

Jefferson Salamanders  are a delicate endangered species that breed in the springtime melt-pools that form in the woodlands on Burlington's escarpment. They cannot survive the assault on their breeding grounds by a massive open-pit mining operation in their environmental neighbourhood. We've hired a biologist to do the science necessary to make the case against Nelson Aggregate's claims that they can mitigate the impact of their new pits on this (and other) tender species. We need help from like-minded people to fund our biologist. 

Donate $100 and Adopt-a-Jeff

For a minimum $100 donation you 'adopt' a 24-inch salamander, hand-cut by a local craftsman from acrylic, and ready to be painted and/or labelled with your name. We'll display your salamander at our Jeff Exhibit on the east side of Cedar Springs Road, between Number Two Sideroad and Number One. 


IF you want to paint your salamander yourself, we'll supply you with materials to paint and label your Jeff. You'll need to pick your Jeff up at a location in North Burlington. We'll share those details once you place your order.


If  you can't make it to North Burlington to retrieve your Jeff, (or you're not feeling artistic) but still want to Adopt-A-Jeff, no problem: we'll paint it for you and label it with your name. If you'd rather remain anonymous, that's fine by us, too. Your Jeff may remain nameless. We'll email you with a picture once your Jeff is on display in our exhibit.


  Click the button below to order your Jeffs.

Adopt a new family pet, support our efforts to save Burlington's Jefferson salamanders, and enjoy a community art exhibit on Cedar Springs Road. Win win win.

A huge thanks to Braniff Intercity Glass for generously donating the acrylic for our Jeff's. Your support is greatly appreciated.

CRITICAL Deadline: April 26, 2021

for essential Objection Letters to the Niagara Escarpment Commission



About Us

We are a non-profit organization of volunteers opposed to an application from Nelson Aggregate to blast an additional 124 acres into two open-pit limestone mines on Mt. Nemo in Burlington's UNESCO World Biosphere Reserve on the Niagara Escarpment.

Our Mission

To preserve the ecological integrity of rural Burlington, and to advocate for healthier communities by protecting our land, air and  water.

Once It's Gone, It's Gone


Nelson Aggregate has 2 years to respond to your MNRF objection letter. As soon as they do, you have just 20 Days to confirm your opposition or your concern is considered resolved.

"If they blow a hole in my backyard, everyone is gonna run away. And the creeks won't flow to the Great Lake below; will the water in the wells still be okay?"

We are THRILLED to announce that CORE Burlington has partnered with the Small Change Fund. The Small Change Fund, founded in 2008, works with its community partners to raise funds in support of important environmental  issues.

Small Change Fund believes in people. They believe that people know how to fix the problems in their communities, their cities, and their country. They believe people can make change without long studies, thick reports, and big money.

Small Change Fund is...

people helping each other by crowdsourcing big change.


All your donations will go towards hiring a team of specialists that will help CORE Burlington demonstrate the environmental, cultural, economic, and social impacts that further open-pit mining will have on our community. In addition, thanks to Small Change Fund, all donations receive a tax receipt for your records.

Did You Know?

There are 22 licensed quarries in Halton Region alone, covering an area of 3810 acres, producing an average of 7.1 million metric tonnes of aggregate per year.


Halton Region (which includes Burlington) is one of the highest aggregate producers in Ontario.

After 70 long years of open-pit mining on Mt. Nemo in rural Burlington, Nelson Aggregate (in addition to applying for two new quarries) has stated that they plan to continue operations in the existing quarry for 50 more years!

"We have a park. It’s called the Niagara Escarpment and it’s pretty perfect."

Hardly a Fair Trade from the 'People-for-Rocks'

Nelson Aggregate is offering the citizens of Burlington a trade. Let them blow-up an additional 124 acres of prime Niagara Escarpment green-lands and they'll give the city a pretty park. Sometime in the far-away future.

Question: Isn't Nelson Aggregate ALREADY obligated to rehabilitate their existing 500 acre hole in the escarpment...leave it to fill in and form a lake? We don’t need to give Nelson Aggregate an additional 124 acres of our precious green-space in order to receive the 'gift' of a far-off future park.

An exhausted pit is of no value to an aggregate company, and carries significant costs and liabilities. After exploiting tens of millions of dollars from the destruction of the local landscape, giving the community an abandoned pit is no gift: rather, society gifted Nelson Aggregate the right to extract the mineral resource in the first place. Are we going to give Nelson another 50 years in return for a park?



Here's the City of Burlington's response  to Nelson's park-punt.


"Recently, there has been an effort on the part of the Nelson Quarry proponent to frame its quarry application as a gift of a park to the city, contingent on approval of a new multi-decade mining operation on the Niagara Escarpment World Biosphere Reserve."



When will Burlington get

its long-promised lake?

Don't be distracted by the promises of parks-for-people from people-for-rocks.


No 'new' park is worth 124 acres of permanently obliterated escarpment lands.

Steve Lindstrom, Duluth Tribune: Nov, 2013

If Nelson intended to create a park for the community, wouldn’t they have done so already with a portion of the existing quarry that is no longer in use? It seems 'convenient' that their offer to donate the exhausted quarry-land for a park is conditional upon approval of their current application to blast two new pits down the road from the current one.

Once it's gone, it's gone forever


The "lunar" landscape of the current Nelson Aggregate pit on Burlington's Mt. Nemo Escarpment:

a deceased place, eco-carrion.

"What branches grow out of this stony rubbish?"

T.S. Eliot - The Wasteland

Open-pit mining companies make promises of ‘rehabilitating’ the land, but no man-made rehabilitation can replicate the complexity of a bio-diverse ecosystem that has been blasted to its rocky core.

Please marvel as this life-thriving marshland off Cedar Springs Road on Burlington's Escarpment:  less than 3kms down the road from  Nelson Aggregate's currently proposed new west pit site.  Complex ecosystems such as this one can NEVER be replaced.  Once it's gone, it's gone.

Our Objectives

1. Oppose new aggregate mineral extraction, and processing of off-site aggregates, and asphalt reprocessing on Burlington escarpment lands.

2. STOP the importation of any fill into Nelson Aggregate's below-the-water-table Mt. Nemo open-pit quarry mine.

3. Protect the environmentally sensitive biodiversity of the Burlington escarpment woodlands, wetlands, water courses and prime agricultural lands, consistent with our UNESCO World Biosphere Reserve designation. 

4. Advocate on behalf of all living organisms, particularly species-at-risk

This tract of prime farmland on Burlington's escarpment, is on it's way out...

5. Protect and improve the quality of our air, and the quality and supply of our water.

6. Address concerns associated with HEAVY truck traffic including noise, vibration, pollution, community safety, and road infrastructure

7. Advocate for a comprehensive, science-based assessment of all potential negative impacts, including cumulative impacts, of more aggregate extraction on the Burlington escarpment.


8. Champion our rural community's quality-of-life, and the safe and peaceful enjoyment of our homes and farms for our families and future generations.

"When no one is left to mourn,

when we are sure that the butternut trees have gone

and only the dust rises from the north bluff;

when we cannot go back to our promises

because we have lost what is there to save,

and there is nothing left to take,

the price of the limestone will be nothing

compared to the cost of our mistakes."
