I'm traveling in Belgium with a Canadian laptop power supply that has a three-prong Type B plug. I only have a basic two-prong adapter for EU outlets and have already used it for several days. At one point, the laptop chassis felt slightly tingly when I ran my fingers across it, which made me concerned about grounding and safety. The power supply is rated for 100–240 V AC at 50/60 Hz, with a 19.5 V DC output at up to 11.8 A. Is it safe to keep using this setup, or should I get a properly grounded EU cable or adapter?

Since the power supply accepts 100–240 V at 50/60 Hz, it can handle European mains voltage directly; you do not need a voltage converter. However, you should use a properly grounded EU adapter or replace the detachable mains lead with an EU-compatible grounded cable. A basic two-prong adapter removes the earth connection, which is especially concerning because you felt tingling from the laptop chassis.
A proper EU mains lead is probably the simplest solution. Bring the power supply to a shop so they can match the connector and confirm the cable is rated appropriately. Do not improvise with exposed contacts or continue using a setup that makes the laptop feel electrically tingly.
The adapter itself does not convert voltage; it only changes the plug shape. That is fine here because the charger is marked for 100–240 V input. The important part is getting the correct earthed cable or adapter from an electronics, travel, electrical, or similar local shop rather than relying on an ungrounded two-prong connection.
Don’t keep using the two-prong setup. If the power supply has a detachable cable—often a three-lead IEC C5 “cloverleaf” cable—you can usually buy an EU version and plug it directly into the supply. Otherwise, get a proper Canada-to-EU adapter that preserves the earth connection. Stop using it if the tingling returns, and inspect the cable and charger for damage.
The voltage and frequency ratings confirm compatibility, but they do not make losing the protective earth safe. The grounding issue and the tingling sensation are separate concerns from voltage conversion.
