Jim Balsillie's bid to buy the Phoenix Coyotes and move the team to Canada may have been rejected in court, but the Blackberry billionaire isn't slowing down his efforts to bring a seventh NHL franchise north of the border.

In an email he sent Thursday to fans signed up for his Make It Seven movement, Balsillie urges his supporters to take part in a rally on Friday in downtown Hamilton.

Fans are asked to gather directly behind Copps Coliseum, the proposed new home of the team, for part of what Balsillie and co. are calling "Make It Seven Day in Canada."

"Make It Seven day is all about providing a voice to Canadian hockey fans, while raising money for minor hockey teams across the country," Balsillie said in an email to supporters signed up for the movement. "Canadians have proven themselves to be the best hockey fans in the world. They need to be heard."

The rally comes only four days after his $212.5 million US bid to buy the struggling Phoenix Coyotes and move them to Hamilton was rejected in a Phoenix bankruptcy court.

Balsillie and his team say the judge's ruling doesn't mean the Coyotes won't move to Hamilton. On Wednesday, Balsillie launched a letter-writing campaign, asking fans to write letters to NHL commissioner Gary Bettman.

The NHL is looking for a buyer interested in keeping the Coyotes in Phoenix.

Make It Seven corporate partners Home Hardware, Prime Restaurants, Labatt Blue, Dewalt, and FirstOntario Credit Union are supporting Friday's rally.

"It all adds up," Balsillie said. "We have a market that is crying out for an NHL franchise, great fans, a plan for a state-of-the-art arena and tremendous corporate support."
