Mark Zekulin, president of Tweed Marijuana Inc., a subsidiary of Canopy, said it would be "heartbreaking" if the federal government shut down the licensed-producer system entirely. But he doesn't expect that will happen.
"We've built a world-class facility ... and are producing very high quality product that you can't get anywhere else," he said. "I don't think six months from now it's just going to get shuttered and people are going to be out of jobs."
Peace Naturals CEO Mark Gobuty said personal growers and larger licensed producers can co-exist.
"We're all allowed to grow tomatoes and cucumbers at home, but how many of us do?" he asked. "If that is what's in the best interest of all Canadians, then I'm all for it."
But Ronan Levy of Canadian Cannabis Clinics, a network of Ontario medical marijuana clinics, said allowing people to grow their own marijuana might make doctors more wary of prescribing it.
"Can you imagine what it would be like if you went to a doctor, they prescribe antibiotics, and you got to go home and mix up your own antibiotics? I don't think doctors are going to be comfortable with that," he said.
