Robertson and Calgary Mayor Naheed Nenshi plan to face a friendly bet for the Canucks vs. Flames playoff series, but they haven't decided the terms.
Nenshi has been bombarded with suggestions on Twitter to wager beer or beef — along with several jabs at Vancouver's riotous past.
Robertson said he's "all ears" for suggestions from Vancouverites, as he's at a loss.
"It's a challenge when you look at how much better our weather is," said Robertson Tuesday.
"We have all the advantages here on the West Coast, so I'm not sure we need much from Calgary right now.
"We just need them to go away in the playoffs."
The game starts at 7 p.m. PT on Wednesday at Rogers Arena in Vancouver.
