What happens during cremation? A complete step-by-step guide

If you're reading this, you may be arranging cremation for someone you love -- and the not-knowing feels heavy. You want to understand what actually happens, but the thought of looking into it can be overwhelming.

You're not alone in that feeling. Many families tell us the same thing: they wanted to know the process before making a decision, but most of the information out there felt either too clinical or too vague.

This guide walks you through what happens to the body during cremation and everything that comes before and after. We'll answer the questions most families have, including the ones that feel uncomfortable to ask.

What is cremation?

Cremation is the process of reducing the body to bone fragments using high heat in a specialized chamber called a cremation retort. The process takes 1.5 to 3 hours, and the remaining bone fragments are processed into a fine, sand-like material that families commonly call "ashes."

Cremation has become the most common choice in Canada. According to the Cremation Association of North America, 76.7% of Canadians now choose cremation -- and that number is expected to reach 80.7% by 2029.

Direct cremation -- sometimes called simple cremation -- means the cremation happens without a funeral service beforehand. It's the most straightforward and affordable option. Many families choose a direct cremation and then hold a memorial or celebration of life on their own terms, whenever the timing feels right.

The cremation process step by step

Here's what happens from start to finish. Every licensed crematorium follows strict protocols to ensure your loved one is treated with care and dignity throughout.

Step 1: Authorization and documentation

Before cremation can happen, the cremation provider needs legal authorization. In Quebec, this is governed by the Funeral Operations Act.

Authorization must come from the person closest to your loved one, following a specific legal order: spouse first, then adult children, then parents, then siblings. If your loved one left written instructions about their wishes, those take priority.

You'll also need a death certificate, which is usually handled by the funeral home or cremation provider. In Quebec, there's a minimum 6-hour waiting period after death before cremation can proceed.

If this paperwork feels overwhelming -- and it often does -- your cremation provider should handle most of it for you. At Cleo, we take care of all the documentation so you can focus on your family instead of forms.

Step 2: Identification and tracking

This is one of the most important steps, and it's designed to answer a question many families have but hesitate to ask: "How do I know I'll receive my loved one's ashes?"

When your loved one arrives at the crematorium, staff verify their identity and assign a unique metal identification tag. This tag stays with your loved one through every step of the process -- during preparation, throughout the cremation itself, and into the final container of ashes you receive.

Cremation chambers are designed for one person at a time. Your loved one is never combined with anyone else during the process. This means there's a clear, documented trail from the moment your loved one arrives at the facility to the moment you receive the ashes.

Step 3: Preparing the body

Before cremation, the body is carefully prepared. This includes removing any medical devices like pacemakers or defibrillators, which need to be removed before cremation for safety reasons. The cremation team also removes jewelry and personal items, which are returned to the family.

Your loved one is placed in a cremation container -- a simple, combustible enclosure. A traditional casket is not required for cremation. In Quebec, any container that meets public health standards is acceptable. Many families choose a simple container, and that's a perfectly dignified choice.

If your loved one was wearing something meaningful -- a wedding ring, a watch, a necklace -- let your cremation provider know. These items are carefully removed and returned to you before the cremation begins.

Step 4: The cremation itself

A question many families have but are afraid to ask: does the body feel anything? No. After death, the nervous system has completely stopped functioning. There is no sensation, no awareness, and no pain.

The cremation takes place inside a specialized chamber called a retort, which reaches temperatures between 1,400 and 1,800 degrees Fahrenheit (760 to 980 degrees Celsius). At these temperatures, the body is reduced to bone fragments over the course of 1.5 to 3 hours. The exact time depends on the person's body size. The chamber processes one person at a time.

Step 5: Preparing the ashes

After the cremation is complete and the chamber has cooled, the cremation team carefully removes any remaining metal -- dental work, surgical pins, artificial joints. These are separated and recycled.

What remains are bone fragments. The team uses a device called a cremulator to process these fragments into a finer, more uniform consistency. This is what families receive as "ashes," though technically they're processed bone fragments with a texture similar to coarse sand.

Step 6: Return to family

The processed ashes are placed in a container -- either a basic urn, a velvet bag, or a container you provide -- along with the original identification tag.

Many families tell us this moment feels more emotional than they expected. That's normal -- and there's no right or wrong way to feel when it happens.

The timeline from death to receiving your loved one's ashes is typically 3 to 7 business days in Quebec, depending on factors like documentation processing, the crematorium's schedule, and any coroner involvement. Your provider should give you a clear timeline at the start.

At Cleo, we deliver the ashes directly to your home -- even if that means driving through difficult weather. Families can also arrange to pick them up if they prefer.

What do the ashes look like?

This is one of the most common questions families have, and it's completely natural to wonder.

Cremated remains don't look like the gray ash you might picture from a fireplace. They're actually processed bone fragments, and they have a coarse, sand-like texture. The colour ranges from white to light gray.

The total weight depends on the person's body size. For an average adult, cremated remains weigh between 3 and 9 pounds (roughly 1.4 to 4 kilograms) -- about the weight of a bag of flour.

Most families are surprised by how substantial the remains feel. It's a tangible, grounding thing in the middle of something that can feel very abstract.

How long does cremation take?

There are two timelines to understand:

The cremation itself: 1.5 to 3 hours, depending on body size and composition.

The full process from death to return of ashes: Typically 3 to 7 business days. This includes:

  • Documentation and authorization (1 to 2 days)
  • The 6-hour minimum waiting period required by Quebec law
  • Scheduling at the crematorium
  • The cremation and processing
  • Preparing and delivering the ashes to you

Some situations take longer -- for example, if the coroner needs to investigate the cause of death, or if there's a delay in obtaining the death certificate. Your cremation provider should keep you informed throughout.

We've written a separate guide on cremation timelines that covers each stage in more detail.

Common questions and concerns about cremation

These are the questions families ask us most often. There's no such thing as a strange question when you're going through this -- we hear these every day, and asking them is a sign you care.

Does the body feel pain during cremation?

No. As we covered above, all nerve function ceases after death -- your loved one feels nothing during cremation.

Is a casket required for cremation?

No. In Quebec, cremation requires a combustible container, but it doesn't need to be a casket. Many families choose a simple container, which keeps costs down without any compromise to dignity. If a funeral home tells you a casket is mandatory for cremation, that's not accurate.

Are bodies cremated one at a time?

Yes. Licensed crematoriums process one person at a time in each cremation chamber. This is both a legal requirement and a professional standard. The identification tag system tracks your loved one through the entire process, ensuring the ashes you receive belong to them.

Can family members watch the cremation?

Some crematoriums offer "witness cremation," where family members can be present for the beginning of the process. This is sometimes important for families with specific religious or cultural traditions, or for those who find it meaningful to be present. Not all facilities offer this, so ask your cremation provider.

Can you still have a memorial service with cremation?

Yes. Cremation and memorial services are completely independent decisions. Many families choose cremation first and then hold a memorial, celebration of life, or religious ceremony on their own schedule -- days, weeks, or even months later. This flexibility is one reason many families prefer cremation. You're not locked into a timeline.

Does my religion allow cremation?

Most major religions permit cremation, though practices and preferences vary. The Catholic Church has allowed cremation since 1963, though it encourages keeping the ashes intact in a sacred place. Hinduism and Buddhism have long traditions of cremation. Judaism and Islam generally prefer burial, but individual practices vary.

Is cremation environmentally friendly?

Cremation has a smaller environmental footprint than traditional burial, which involves embalming chemicals, hardwood or metal caskets, and permanent land use. That said, cremation does use energy and produce emissions. For families seeking the greenest option, alkaline hydrolysis (sometimes called water cremation) is a newer alternative that uses less energy -- and it's legal in Quebec.

What are your options after cremation?

Once you have the ashes, there's no rush to decide what to do with them. Many families keep them at home while they figure out what feels right. Some common options include:

  • Keeping ashes at home in an urn or decorative container
  • Scattering in a meaningful location
  • Placing in a columbarium at a cemetery
  • Dividing among family members using smaller keepsake urns
  • Cremation jewelry that holds a small portion of ashes
  • Burial of the ashes in a cemetery plot

In Quebec, scattering ashes is legal on private property with the owner's permission and in many natural settings.

How much does cremation cost?

Cremation costs vary widely depending on what's included. In Quebec -- and particularly in Montreal, where funeral home prices tend to be higher -- knowing your options matters. In Canada, direct cremation typically ranges from $1,500 to $5,000. The most important thing to look for is whether the price is all-inclusive or whether there are additional fees for transportation, documentation, or other essentials.

At Cleo, our complete cremation service is $1,900 all-inclusive. That covers everything: transportation from the place of death, the cremation itself, death certificates, a basic urn and velvet bag, and home delivery of the ashes. No hidden fees, no weekend surcharges -- the quote you receive is the final price.

Choosing a cremation provider you can trust

If you're planning a funeral for the first time, choosing a cremation provider can feel daunting. Here are some things to look for:

Ask for a clear, all-inclusive price. A trustworthy provider will give you an itemized quote that covers everything. Be cautious of "starting at" pricing -- it often means additional fees for services you'd expect to be included.

Ask about their identification process. You should feel confident that strict protocols are in place to track your loved one throughout the entire process.

Ask about the timeline. A good provider will give you a clear estimate of when you'll receive the ashes and keep you updated along the way.

When you call, pay attention to how they treat you. You're going through one of the hardest weeks of your life. The person on the other end should answer your questions patiently, explain things clearly, and never make you feel rushed or pressured. If they do -- that tells you something.

Red flags to watch for:

  • Pressure to upgrade or add services you didn't ask for
  • Vague or "starting at" pricing that doesn't include a total
  • Reluctance to explain their identification and tracking process
  • Making you feel that choosing simple cremation is somehow "less"

Understanding what happens during cremation helps you feel in control

Knowing what happens during cremation won't take away the grief. But many families tell us it takes away some of the fear and uncertainty -- and that makes a real difference during the hardest week of your life.

Whatever you decide, there's no wrong choice. Whether you choose a simple direct cremation or a full service with a ceremony, you're honouring your loved one in the way that feels right for your family.
