TORONTO -- The Toronto Argonauts have a chance to celebrate the Grey Cup's centennial on home turf this week. The Calgary Stampeders will do their best to spoil the party.

The 100th Grey Cup will be Toronto versus Calgary on Sunday at the Rogers Centre, the Argonauts' home field.

The Argos last won a Grey Cup at home in 1952 -- they lost one in Toronto in 1982 and now they're home again in 2012 -- each time exactly 30 years apart.

The Stampeders are playing in the championship game for the first time since winning it against the Montreal Alouettes in 2008. That year they upset the Als on their home turf at Olympic Stadium.

Calgary earned a berth this year by upsetting the defending champion B.C. Lions 34-29 in the CFL West final at B.C. Place Stadium, while the Argonauts advanced by stunning the Alouettes 27-20 in Montreal in the East final yesterday.

Off-season acquisition Ricky Ray powered Toronto with 399 yards passed, including a touchdown strike, as the Argonauts reached the Grey Cup for the first time since 2004, when they won their 15th title with a victory over B.C.

Stampeders quarterback Kevin Glenn threw for three touchdowns as Calgary denied the Lions a chance to repeat.

For the 33-year-old Glenn it will be his first chance to play in a Grey Cup after 12 season in the CFL. He was denied the opportunity in 2007 after he led the Winnipeg Blue Bombers to victory in the East Final but suffered a fractured arm.

That year's Grey Cup, which the Bombers lost to the Saskatchewan Roughriders, was also in Toronto.

The last time the Stampeders faced the Argonauts in the CFL championship was in 1991 in Winnipeg, where Toronto won 36-21 with the help of Rocket Ismail. The wide receiver recorded an 87-yard touchdown on a kickoff return and was named game MVP.
