When you invest with Mercer Invest Wise, your assets are actually held by Canadian ShareOwner Investments Inc., Mercer Invest Wise's custodial broker. In other words, ShareOwner executes trades and is where your securities are held. ShareOwner is regulated by IIROC and is a member of the Canadian Investor Protection Fund (CIPF), which is standard for brokerages in Canada. More on the CIPF here.
In the extremely unlikely event that Mercer Invest Wise was to go out of business, your account would remain safe and be largely unaffected. All securities are registered in your name, and if we were to close, you could choose to keep your money with ShareOwner or transfer it to a new advisor or your bank account.
Mercer Invest Wise is partnered with Wealthsimple Inc. who is a registered Portfolio Manager in Canada. Securities in your account may be protected up to $1,000,000 CDN through Canadian ShareOwner Investments Inc., if this brokerage were to go insolvent. See www.cipf.ca for more details.
