CBM Aggregates

If you plant trees today, when do they become a forest? 🌳

There isn't a single moment when that happens.

A forest develops gradually as trees mature, vegetation becomes more diverse and the structure of the landscape changes. A growing canopy creates different levels of shade. Fallen leaves and branches contribute organic material to the soil. New habitat becomes available for birds, mammals, insects and other wildlife. 🦌

This complexity is one reason long-term thinking matters in land rehabilitation.
Where forest is an appropriate rehabilitation objective, planting and establishing vegetation can help begin a much longer ecological process. Habitat continues changing as plants mature and natural processes become established. 🌱

National Forest Week reminds us that the forests we enjoy today took time to develop.

What could the trees we plant and landscapes we rehabilitate today look like to the generations that experience them decades from now? 🍂

Why does Ontario look so different only a few weeks after summer ends? 🍁
One of the answers is happening inside the leaves.

As daylight decreases and temperatures cool, deciduous trees begin preparing for winter. Chlorophyll, the pigment responsible for their green colour, breaks down. As the green fades, yellow and orange pigments that were already present become easier to see. 🌳
Other chemical processes can contribute to the brilliant reds and purples that make Ontario's autumn landscapes so recognizable.

The autumn equinox marks the astronomical beginning of fall, but the transformation of the landscape unfolds according to temperature, daylight, weather and the characteristics of individual tree species. 🔎

It's a remarkable natural process happening across forests, parks and neighbourhoods throughout the province.

He began with an ambitious goal: inspire Canadians to support cancer research. What followed became part of Canada's story. 👟

In 1980, Terry Fox set out on the Marathon of Hope, attempting to run across Canada to raise funds for cancer research.

His journey ended before he could complete the route, but Canadians refused to let the cause end with it.
Communities kept running. People kept fundraising. Volunteers organized events. New generations learned Terry's story and discovered why he started. 🇨🇦

The Terry Fox Run has since become an enduring Canadian tradition built around determination, hope and a shared commitment to advancing cancer research. 🏃

Today, we recognize every participant, volunteer, organizer and supporter helping continue that work.

More than four decades later, Canadians are still running for the cause Terry believed in. 👏

Water changes with the seasons. Monitoring helps us understand how and why. 💧

Rainfall, snowmelt, dry periods and changing groundwater conditions can influence water levels and characteristics throughout the year.

That's why environmental monitoring isn't based on a single observation.
At aggregate sites, monitoring programs can collect information about groundwater, surface water and water quality over time. 📋 Examining that information across seasons helps environmental teams establish typical conditions, identify trends and recognize changes that warrant closer attention.
Reliable data provides a stronger foundation for responsible decision making and long-term water management. 🔬

World Water Monitoring Day recognizes the science, planning and ongoing observation involved in managing one of our most important natural resources.

Consistent monitoring helps turn individual measurements into meaningful information about how water conditions change over time. 🌿

Ever wondered what happens inside an aggregate pit?

On Saturday, September 26, we’re opening our doors and inviting the community to come see for themselves.
Join us for the CBM Annual Open House in Puslinch. Take a guided bus tour through the operation, see how aggregates are produced, visit areas that have been rehabilitated and restored to nature, and meet the people behind the work.

It’s an opportunity to learn more about the materials we produce and the role aggregates play in the infrastructure we rely on every day, while getting your questions answered directly by our team.

📅 Saturday, September 26 | 11 a.m. to 2 p.m.
📍 7366 McLean Road, Puslinch
🎟️ Free admission
🍽️ Complimentary lunch, family activities, and door prizes

How much aggregate does a project need before we start thinking of it as an aggregate application? 🪹

A terrarium gives us an interesting answer.

Not very much.

Sand, gravel and individual stones can be used in reptile enclosures and terrariums as substrate or landscape materials.

Someone designing an enclosure may select the material according to the setup they are creating and then arrange it at an extremely small scale.
That is a dramatic contrast with the way aggregate is usually handled industrially.
Instead of tonnes moving through equipment, the material may be poured from a small bag.

Instead of a loader positioning it, someone may be moving individual stones by hand.
Yet the basic materials remain familiar.
Sand. Gravel. Stone.

The quantity may change by several orders of magnitude, but the physical materials are still part of the same broad aggregate family.

Sometimes the best way to appreciate scale is to shrink the application until it fits inside a living room.
