Yeah, now it looks like the Canadians rushed to judgement.
Now that we know the two gunmen shouted "allahu akhbar" before opening fire on a crowd it seems more like a case of workplace violence.
That could easily have been said in mockery, especially given that at least one of the two suspects (Alexandre Bissonette) who said it is unlikely to be a big fan of Islam. How many devout Muslims that sincerely say "allahu akhbar" have Facebook likes including Trump, the far-right nationalist-front party in France, the Israel Defense Forces, and United with Israel?
If he is in fact a strong Israel supporting non-Muslim, then yelling "allahu akhbar" while murdering Muslims is just as way of saying "I am killing you for your religious beliefs".
The other suspect has an Arabic name (Mohamed Kadir), but reports suggest he may be a native of Quebec and a University student, so who knows what his personal politics or religious views are.
Whatever this turns out to be, "workplace violence" is among the least plausible explanations.
I wouldn't bet on it being "terrorism" in strict technical sense either.
One problem that leads to the loose use of the word "terrorism" is the lack of other terms for mass murders where the victims are not selected for any specific personal reason and connection to the shooter, as is the case with most murders. These guys could have been motivated by religious hatred and targeted random Muslims, but it still not be "terrorism" in the technical sense. Yet, it would have psychological underpinnings and implications for public safety and political climate that are much closer to terrorism than the 99% of murders.
