Normally Belgian Nationals do not need a visa to get into Canada. They only need an ETA (Electronic Travel authorization) which can be obtained online. It’s usually valid for 90 days and only valid for arrivals by air. This Canada Tourist Visa Application in Belgium post is meant for people who reside in Belgium but are not yet Belgian Nationals and whose nationality or passport requires a visa. In my case, I live in Belgium but I have a Philippine passport so I need a visa to enter Canada. The process for me was pretty straightforward but a bit of a hassle specially if there are no Visa Application Centers in your city or nearby. All in all, the process took about a month so give this some consideration for your travel plans.
