Direct answer
Ketone esters can be sold in Canada as a supplement or cosmetic ingredient, classified as "Sold as a supplement". That is not drug approval: Health Canada has not evaluated any health claim, and injectable or "research use only" versions fall outside supplement rules, so that label does not make human use lawful. On the evidence, 2 human studies are cited on its profile.

What Ketone esters is
Sold to give you the benefits of ketosis without fasting. In trained cyclists, an acute dose made 20-minute time-trial performance worse.
Ketone esters raise blood ketones within minutes, which makes them the most direct way to test whether the ketone bodies themselves produce the effects attributed to fasting and ketogenic diets. That is a genuinely useful experimental tool and it is also why the results are awkward for the marketing.
Mechanism: An ester of beta-hydroxybutyrate, typically the monoester of R-3-hydroxybutyl R-3-hydroxybutyrate, which is hydrolysed in the gut and liver to release free beta-hydroxybutyrate and its alcohol precursor. That raises blood beta-hydroxybutyrate within roughly 30 minutes to concentrations comparable with several days of fasting, without the fasting.
Regulatory history: Sold as a dietary supplement or food for special dietary use. Not an approved drug and not approved for any indication.
How Health Canada treats this kind of product
Authorises drugs for sale through a Notice of Compliance and Drug Identification Number. A compound that is not authorised for sale cannot lawfully be sold for human use, and personal importation of prescription drugs is limited.
The classification above is the The Longevity Archive reading of Health Canada, Health Products and Food Branch listings for Ketone esters at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
