No (only the US has a "grace period"). I found this at

It is important to keep in mind that the one-year "grace period" for
publication under 35 U.S.C. 102(b) is unique to U.S. patent practice.
Patent rights outside the U.S. may be destroyed at the time that an
invention is disclosed in an electronic publication if a patent
application has not been filed. Under the European Patent Convention,
for example, an invention is considered new if it does not form part
of the "state of the art" before the date of filing of the European
patent application (Article 54 EPC). The Guidelines for Examination
in the EPO instruct examiners that the state of the art is very
broad, and that there "are no restrictions whatever as to the
geographical location where, or the language or manner in which the
relevant information was made available to the public" (Id. at Part
C, Chapter IV, 5.1). The Guidelines also explain that "[a]vailability
to the public . . . includes all possibilities which technical
progress may subsequently offer of making available the aspect of the
state of the art concerned" (Id. at Part D, Chapter V, 3.1.1). Thus,
the European Patent Office clearly focuses on the availability of a
disclosure, regardless of form.
