Insured up to $1m CAD in Canada through the CIPF.
One thing I came across to watch out for though is that if you hold fixed income securities (e.g. GICs) that are issued by the same bank as the brokerage account, then if it goes bust, the securities are NOT covered by insurance.
"CIPF does not cover: the insolvency or default of the company or organization that issued your security"
For example, if you hold a $500k GIC issued by TD Bank in a self directed TD brokerage account, and TD goes bust, then you're gonna have a bad day.
