Happy Friday!

Here are 5 things to know this morning as you wrap up your work week: the RCMP's deputy commissioner outlined the roadblocks in fighting terrorism in Canada; the federal government is set to announce its commitment to UN peacekeeping efforts; Toronto police are investigating after three people were killed in a crossbow attack; Canada Post and its largest union are meeting with a mediator today to try to avoid a strike; and a video of an Ontario man's proposal is touching hearts.

Plus for Flashback Friday, we take a look at the day Elizabeth May was elected as leader of the Green Party.

1. CTV Exclusive: In an interview with Mercedes Stephenson, RCMP Deputy Commissioner Mike Cabana ‎says the Mounties receive significant amounts of information from CSIS and the FBI on potential terror suspects, but are barred from bringing charges.

2. UN commitments: The federal government is set to announce how many troops and money it will commit to the United Nation’s peacekeeping efforts. The government isn’t expected to sign on to a specific mission, rather show that it is committed to peacekeeping efforts as they arise.

3. Crossbow attack: Three people are dead after a crossbow attack in Toronto on Thursday. Toronto police say that there is a link between the crime scene in Scarborough and a suspicious package found downtown.

4. Strike notice: Canada Post and the Canadian Union of Postal Workers will be meeting with a special mediator this morning in an attempt to come to an agreement before a strike notice comes in to effect on Sunday. 

5. Memorable proposal: Video of an Ontario man proposing to his girlfriend has gone viral after he used a time capsule they buried together five years earlier. Troy Reddington dug up the capsule he and now-fiance Jennifer Storrar buried in a campsite on Eagle Lake in South River, Ont. Instead of finding mementos, Reddington swapped it all out for a simple note asking for Storrar to marry him.

And one more thing for "Flashback Friday": Elizabeth May became the leader of the Green Party 10 years ago today after winning more than 60 per cent of the vote at the party's convention in Ottawa.
