Toronto Mayor John Tory said the gun control measures proposed by Liberal Leader Justin Trudeau are good steps, but he wants to see more from all parties.
"We will take this as a step forward," Tory said after the prime minister announced if elected, his party would ban military-style assault rifles and will work with the provinces to allow cities to enact handgun bans.
Trudeau was asked why he wouldn't add the handgun ban to the assault rifle one, and said it's because of municipalities wanting more local powers.
But that creates a problem for an area like the GTA, where a city like Toronto could ban handguns, but theoretically others like Mississauga or Brampton could opt not to.
"It won't be as effective as a national handgun ban, which is what I have called for," Tory said. "But again, it is a step in the right direction towards tougher gun control."
A group of families directly affected by last summer's Danforth shooting however went further than Tory, calling the measure disappointing.
Ken Price's daughter was shot in the attack and tells the Canadian Press it's not enough.
"To put that to the municipalities, I'm still not sure how that's going to work," he said. "If Brampton says yes and Toronto says no, how does that help?"
Tory also repeated his calls for cracking down on gun smuggling across the U.S. border, as well as stricter bail conditions for repeat offenders and those involving guns.
He said the bare minimum with the border is investing in control points where guns can be smuggled in various ways, such as taped under cars or in cargo.
"There's the more difficult question of what you do in uncontrolled border points," he said, adding that would include more monitoring in those areas, as well as more advanced technology.
The Liberals say there would be more announcements about securing the border during the campaign.
Tory faces another challenge however with Premier Doug Ford, who would have to sign off on municipal powers for the ban.
Ford has said a handgun ban wouldn't work and would only hurt law-abiding citizens.
But Tory seemed more optimistic.
"I think Mr. Ford and I are both interested in saving lives, and I think that this kind of a measure, I would argue it's going to save lives," he said. "None of these measures in and of themselves are going to solve the problem, but I believe that a handgun ban for example would make a difference."
