The Canadian Investment Regulatory Organization has published educational content on extended hours trading and guidance confirming that dealers must comply with the same applicable regulatory requirements outside core trading hours. The update highlights the different market conditions investors may encounter and reminds dealers of their disclosure obligations. Extended hours trading may involve lower volumes and liquidity, greater volatility, wider bid ask spreads and prices that differ significantly from those during regular market hours. Market reactions to earnings, economic reports and breaking news may also be amplified. Investors are encouraged to understand order types, how their orders will be handled and whether extended hours trading aligns with their objectives and risk tolerance. Dealers remain subject to Canadian Investment Regulatory Organization rules, marketplace rules and applicable securities legislation during extended sessions. They must disclose the risks to clients, while availability may vary among investment dealers.
