Shooting at Belleville, Ont. synagogue on Yom Kippur

A shooting at a small synagogue on a residential street in Belleville, Ont., left a police officer in critical condition and bullet holes in the building’s stained-glass windows as worshippers gathered on Sunday night to mark Yom Kippur, the holiest day of the Jewish calendar.

The details: A 29-year-old man armed with a shotgun opened fire on a policeman stationed outside the Sons of Jacob synagogue, initiating a shootout, said Kristy Denette, spokeswoman for the Special Investigations Unit. The agency handles cases involving Ontario police that result in death or serious injury.

Watching: The suspect was also injured and is in hospital in life-threatening condition, according to the SIU. The officer, Constable Jeff Smith of the Belleville Police Service, is in critical but stable condition.

Ottawa introduces sweeping legislation on first day back

On the first day back to parliamentary sittings the federal government introduced sweeping legislative changes aimed at reducing labour disruptions in federally regulated sectors and speeding up project approvals.

The changes: The new federal review rules represent a partial dismantling of environmental policies that were previously criticized by the energy sector. At more than 240 pages, the omnibus legislation references changes to about two dozen different federal laws.

The critics: The bill’s labour code changes appear inspired by high-profile labour disruptions in recent years. And they’re drawing the ire of unions and labour experts, who say that the amendments will effectively dilute federal employees’ right to strike.

British Columbia Conservatives regroup

Four dissident MLAs are rejoining the BC Conservatives as the province’s Opposition attempts to bolster its ranks ahead of a possible snap election and just a day after its leader resigned.

Who else: Former BC Conservative leader John Rustad was also invited to rejoin the party’s caucus, just days after he was expelled by Kerry-Lynne Findlay. Her resignation followed weeks of upheaval with 13 defections or expulsions.

Opinion: Is David Eby about to gamble away his government?

Canadian vaccine aims to fight Ebola in Congo

Congolese authorities have begun rolling out a Canadian-developed vaccine in an attempt to protect 20,000 health workers from a fast-rising Ebola outbreak, but Ottawa could be doing more to develop vaccines that are effective for the current virus, experts say.

The details: The vaccine, known as Ervebo and manufactured by Merck, was first developed at the National Microbiology Laboratory in Winnipeg. Its protective value against the Bundibugyo Ebola virus – the cause of the latest outbreak – is unknown, but health authorities have decided to try it in a large-scale study. There are no proven vaccines for Bundibugyo.

The Take

From a broader perspective, the Iran war has also shaken confidence in the Gulf’s reputation as an island of relative stability in a Middle East habitually wracked by conflict. For a country like Saudi Arabia looking to attract international investment for its Vision 2030 economic reform program, that could be a problem.

Saudi Arabia is caught between Iran and a hard place, writes Dennis Horak.

Editor’s note: In Friday’s edition of the newsletter, we stated that Donald Trump would see Canada’s associate membership with the European Union as a hostile act. That wasn’t quite right; the U.S. President said he could see it as a hostile act. We’ve updated the newsletter accordingly.
