Canadians learned Tuesday about a possible terror attack that happened Saturday in Toronto, four days earlier.

That’s how long it took journalists to ferret out the tale of a violent and concerning incident that thankfully ended without tragedy.

This is unacceptable and alarming. Both the incident itself and the fact the public remained in the dark about it for four days.

But there is still much we need to know.

Rehab Dughmosh is currently in custody facing seven charges including two counts of assault with a weapon.

The 32-year-old mother of two allegedly entered a Canadian Tire store and, according to what sources told the Sun, became agitated and threatened to kill “white people” to avenge bombings in Syria.

“I’m here for Syria. I’m going to kill everybody,” the woman reportedly screamed. “I want to kill all you white people. I’m from ISIS. I’m from Syria,” she allegedly told shocked onlookers.

“You people are killing my people. You people are dropping bombs on my people.”

Dughmosh allegedly shouted “Allahu Akbar” — God (Allah) is greater — before swinging a golf club at employees — at the same time of bloody terrorist attacks in London.

She apparently pulled a large knife, described as a butcher’s knife, from her clothes but was subdued by staff. In court, before her bail hearing began, she pledged allegiance to ISIS and its self-proclaimed caliph Abu Bakr al-Baghdadi.

Police and the RCMP are probing Dughmosh’s travel past, her place of worship and her associates.

It’s not yet clear whether or not in fact this incident was a planned terror attempt, or whether she was acted out because of illness or inner demons.

But clearly, if the reports are accurate, this episode was inspired in some way by global, Islamist terrorism.

As U.K.’s Prime Minister Theresa May observed following the deadly attacks this past week in London, we must be prepared to deal with a “new trend” in terrorism – inspired terrorism. Small scale attacks on innocent civilians with cars and knives and home-made bombs.

Canada can continue to pretend we are immune to these attacks, or we can address them by fairly but fearlessly looking at measures to keep all Canadians safe, including stringent refugee vetting.
