Matthew Mernagh leaves the Robert S. K. Welch Courthouse in St. Catharines, Ont., Tuesday, Feb. 12, 2013.

ST. CATHARINES, Ont. — A St. Catharines man who came close to changing Canada’s medical marijuana laws before an Ontario court upheld them earlier this month plans to take his case to the Supreme Court.

“We got the ball rolling, kept rolling it,” said Matthew Mernagh, 39, outside a courtroom in St. Catharines Tuesday. “It’s way bigger than me. I’m kind of here for the ride.”

Mernagh was in court Tuesday after his 2008 marijuana production charge was tossed back to the trial courts by the Ontario Court of Appeal.

Mernagh was charged in April 2008 after Niagara Regional Police found 70 pot plants in his St. apartment.

He claimed he needed marijuana to help ease symptoms of fibromyalgia, scoliosis and a seizure disorder, but was unable to get a doctor to sign a medical declaration.

The declarations are required under Canadian law in order to possess or produce marijuana for medical purposes.
