If you live in Europe and you intend to get a Canadian tourist visa from Europe, the probability of getting a visa is higher than people who apply from Iran. People who are applying from inside Iran, it is better to present their travel history to the Schengen area to increase the burden of their case and increase the probability of getting a visa. But European residents are potentially in the Schengen Area and are more likely to get a tourist visa.
