With the new biometric passports of the Ukraine coming out next year, will a visitor visa still be required to enter Canada?
There is no way to know for certain until it happens and the Canadian government decides to update requirements, however, for an educated guess only:
Since citizens of Lithuania and Poland who have obtained a biometric passport (e-passport) are allowed to visit Canada visa-free, it stands to reason that, eventually, Canada may extend the same courtesy to citizens of Ukraine.
There are many reasons, however, that Canada could decide to keep the Ukraine on the visa-required list. Again, we won't know, until we know; ya know?
Ukraine is not on the list of countries and effective dates and “If you submit your application in person at a visa application centre (VAC) that offers biometric services before the date the requirement takes effect for your country, you will not have to pay the biometric fee and you can get VAC application services at no cost.”.
This may suggest that visas will still be required since "You can give your biometrics at the VAC in Kyiv and Lviv” but it seems visas are at present required nonetheless.
As of early 2017, Canada still requires a visa for Ukranian passport holders (usually).
