Federal court determined Galloway was no security risk

Federal Court slams government interference in Galloway ban | rabble.ca
The Federal court determined that former British MP George Galloway was no national security risk
According to Justice Mosley, "the main reason why the respondents [the
Federal government] sought to prevent Mr. Galloway from entering Canada
was that they disagreed with his political views."
...
"This ruling confirms what we have been saying from the beginning: Jason
Kenney attempted to ban Galloway because he disagreed with his views,"
says James Clark, a member of the Toronto Coalition to Stop the War and
an applicant in the case. "This kind of behaviour is completely
unacceptable in a democratic society, and represents a serious attack on
Canadians' free speech rights. We are pleased that the Court agrees
with us."

Galloway is going to be coming back to Canada soon on another speaking tour.
