EU Visa Requirements

Before the end of March 2017, will the European Union require Canadians to have a visa to travel to the EU?
Yes: 15%
(The requirements have to actually be in place by the end of March 2017.  If a visa requirement is imposed and later rescinded, that counts for this question.)

There seems to be some suggestion that the EU might force Canadians to apply for a visa when travelling to the EU (see articles here and here).  The main issue seems to be that Canada requires visas for Romanians and Bulgarians.  The impression I get from both articles is that a visa requirement is unlikely to be imposed, because it would cut into tourism.  As well, even if a requirement is imposed, it sounds like it would take a long time; the CBC article mentions "late 2016 or early 2017" as the earliest a visa requirement could be imposed.
