Segregated fund contracts vs. mutual funds

If you’ve heard of seg funds – or segregated fund contracts – and wondered how they compare to mutual funds, you’re not alone.  

Both products help you potentially grow your wealth through market investments. What fits you best depends on more than just understanding how each one works. The key difference: segregated fund contracts include insurance protections in addition to growth potential.

The easiest way to think about the difference

A mutual fund works like most other market investments. Your money can potentially grow or lose value with fluctuations in the market. You take on all the investment risk. 

A segregated fund contract works more like trip insurance for your investments. You pay extra fees, and an insurance company guarantees a portion of your original investment (75% or 100%). This protection applies when you die, or when your contract matures (typically ages 100-105). You also get estate planning benefits – like naming beneficiaries who may receive money directly, potentially bypassing probate.  

People often consider these products when they're thinking about retirement or estate planning. Keep in mind, you can hold both products in your portfolio. It’s not an either/or decision. What makes sense depends on your goals, timelines, and overall financial objectives.

Which one might fit your situation?

The right choice isn’t the same for everyone.  Each serves different needs, and the right choice depends on your comfort with risk, your financial situation, and your goals. 

Quick questions to ask yourself: 

  • Are you concerned about what your family would inherit during a market downturn? 
  • Do you want guaranteed lifetime income in retirement? (available on select segregated fund products). 
  • Do you have life insurance or other protections in place?  
  • Do you have a longer time horizon ahead where you can potentially ride out market downturns before you need to access the bulk of your money?  

Everyone’s situation is unique. Here’s how Canadians at various life stages might decide between these two products.

Sarah is 58. She’s been building her savings for 30 years and has about $400,000 in non-registered accounts. She’s planning to retire at 63. What keeps her up at night isn’t her own retirement. It’s what happens to this money if she dies unexpectedly.  

Without guaranteed protection, if Sarah passes away during a market downturn, her children inherit whatever her investments are worth at that time. She remembers 2008 and 2020, when her balance dropped significantly. The thought of her family inheriting less simply because of bad market timing bothers her.  

A segregated fund contract with a 100% death benefit guarantee means her beneficiaries receive the guaranteed amount on her contract or its current market value, whichever is higher. Sarah can also choose how that money is paid out:  a lump sum or regular income payments (payout annuity), depending on what makes sense for her family’s situation. 

There’s an added benefit. With named beneficiaries on her segregated fund contract, the money may pass directly to her children outside of probate, meaning faster access and more privacy. Rules vary by province or territory. A life insurance representative can explain how this works in your province or territory.  

The trade-off: Sarah pays extra fees for this protection. If markets perform well over her lifetime, she’ll have paid more for the peace of mind that protection provided. But for Sarah, knowing her family is protected is worth the cost. If she passes away during a market downturn, her family receives the guaranteed amount on her contract.  

Segregated fund contracts may make sense if: Protecting what your beneficiaries receive matters more than minimizing fees. This is especially true if market conditions at death concerns you.

Joyce is 63. She’s retiring next year. She’ll receive CPP and a small pension, but she needs her $250,000 in non-registered savings to help meet her lifestyle needs. She’s worried about outliving her money. Her mother lived to 97, and Joyce could live 30 or more years in retirement.  

Select segregated fund products offer a guaranteed lifetime income option. If Joyce chooses one of these products, she can receive a set amount every year for the rest of her life, regardless of market performance. The guarantee remains in place if she doesn’t take withdrawals beyond this guaranteed amount. Not all segregated fund contracts offer this feature. A life insurance representative can show her which products include this guarantee and whether it fits her needs.  

The trade-off: Joyce pays extra fees for the guarantee. But she never has to worry about her savings running out during her lifetime.  

Segregated fund contracts with the guaranteed lifetime income option may make sense if: Longevity risk concerns you and you want the certainty of guaranteed income for life. Note: this option is only available on select segregated fund products.

Robert is 52. He plans to work until he’s 67. He has 15 years before retirement. He’s comfortable with market risk and wants to maximize growth. He already has life insurance covering his family’s needs if something happens to him.  

Robert has about $200,000 saved in non-registered accounts. For him, potentially lower fees on mutual funds could mean keeping extra money in his accounts. It could potentially be more when you factor in compound growth.  

For his situation, potentially lower mutual fund fees make more sense than paying for insurance guarantees he doesn’t currently need. Robert’s decision was informed by a comprehensive review with his advisor, who helped him evaluate his existing insurance coverage, risk tolerance, and retirement timeline to determine the right strategy for his specific circumstances.  

The trade-off: Robert saves on fees but accepts full market risk. If he passes away during a market downturn, his family inherits whatever his investments are worth at that time, though his life insurance would provide additional money. If markets crash right before retirement, he might need to delay or adjust his plans.  

Mutual funds often make sense if: You have a longer time horizon before retirement, you have other protections in place, and you’re comfortable with market risk.

Margaret is 72, widowed, and remarried. She has $350,000 in non-registered savings she wants to leave her two adult children from her first marriage. Their finances are separate by mutual agreement. She’s concerned about potential complications after she’s gone. 

Margaret knows that mutual funds held in registered accounts like Registered Retirement Savings Plans (RRSPs) or Tax-Free Savings Accounts (TFSAs) allow beneficiary designations that bypass probate. But her situation is different. She has money in a non-registered account, which doesn’t offer that option with mutual funds.  

If Margaret invests in mutual funds within her non-registered account, her investments will flow through her estate. That means: 

  • The assets go through probate – her Will and estate details become accessible to anyone  
  • Distributions could take 6 to 18 months or longer depending on estate complexity 
  • If her Will is challenged by any party, these assets could be tied up in the courts 
  • Depending on her situation, creditor claims against her estate might affect these assets 

A segregated fund contract lets Margaret name her children directly as beneficiaries on the contract.

When she dies: 

  • The money may pass directly to her children outside her estate, potentially bypassing probate (rules vary by province/territory) 
  • The transfer is private – no public record 
  • Her children typically receive the money within weeks instead of many months 
  • Potential creditor protection may apply (conditions vary based on circumstances) 

For Margaret, the probate bypass and privacy features alone justify the extra fees. She knows exactly where this money is going, and she’s protecting it from potential estate complications. The death benefit guarantee is an added protection – her children receive 75% or 100% of what she contributed depending on the product she chose (or more if markets perform well), even if she dies during a market downturn.  

The trade-off: Margaret pays higher fees than she would with mutual funds. But she gains certainty, privacy, and protection from potential estate disputes that matter more to her than cost savings.  

Segregated fund contracts may make sense if: You have a blended family, complex estate situation, or want to ensure specific assets pass directly to chosen beneficiaries outside your Will with privacy and potential protection from estate challenges or creditors.

Your situation is unique. The account type you use, your estate planning needs, your comfort with market risk, and your family circumstances all matter. Whether you need the estate planning benefits and the guarantees of segregated fund contracts or the potentially lower fees of mutual funds depends on what’s important to you. A Sun Life advisor can review your complete picture and recommend the approach that makes sense for your goals.

Understanding the guarantees 

Segregated fund contracts offer guarantees* that mutual funds simply don’t. It’s also why they may cost slightly more.

* Note: any withdrawals you take will reduce your guarantees.  

Here’s what each guarantee means for you:

Death benefit guarantee 

This is often the most relevant protection for people thinking about estate planning. Your beneficiaries receive the guaranteed amount (75% or 100%), or the current market value if it’s higher. The guaranteed percentage depends on the segregated fund product you choose.

Maturity guarantee 

At maturity, you receive the guaranteed amount (75% or 100%), or the current market value if it’s higher. The guaranteed percentage depends on the segregated fund product you choose. For most contracts, maturity is typically age 100+. The maturity guarantee provides long-term longevity protection until the end of your contract.

Income guarantee option (select products only) 

Some segregated fund products offer an income guarantee option. If you choose a product with this feature, you receive a guaranteed amount every year for the rest of your life. (extra withdrawals you make will lower the guarantee amount).

This option addresses one of the biggest retirement fears: outliving your money. Not all segregated fund products offer this feature. A Sun Life advisor can show you which products include income guarantees and help you determine if this option fits your retirement income needs.  

Mutual funds don’t offer equivalent guarantees.

When to consider each product 

You may want to consider segregated fund contracts if: 

  • Death benefit protection for beneficiaries is a priority.  
  • Estate planning benefits matter (bypassing probate, named beneficiaries) 
  • Guaranteed lifetime income addresses your retirement concerns (select products only) 
  • Potential creditor protection in certain situations, such as bankruptcy or legal proceedings. This can be particularly valuable for business owners, professionals, and freelancers. Conditions and restrictions apply, and rules vary by province or territory. 

You may want to consider mutual funds if: 

  • You already have other life and health protections in place 
  • You’re comfortable managing retirement income without guarantees 
  • You prefer purchasing investments through a variety of channels as segregated fund contracts are only available through licensed life insurance representatives 
  • You want lower fees vs segregated fund contracts

Frequently asked questions

Yes. You can hold both investments because they serve different needs and purposes. There are no additional costs to hold both a segregated fund contract and a mutual fund. A Sun Life advisor can help you understand how each might fit your overall plan.

For the most part, they’re taxed similarly. Tax treatment is complex and varies based on your investment decisions and what accounts your investments are held in. Speak with a tax professional for guidance to your specific circumstances.
