Two years of upward progress will go on the line at Headingley on Friday night when Toronto take on Leeds on their journey to Super League.
Because of the close-fought nature of the soon-to-be scrapped Qualifiers, victory would not guarantee the Wolfpack promotion but defeat would leave them sweating over the outcome of the remaining fixtures in the final round this weekend.
It may not quite be do or die but it is unquestionably the biggest game in the history of the fledgling Canadian outfit, who have the chance to reach their target of Super League inside two years of steady progress through the lower divisions.
The Million-Pound Game was always seen as the more likely route for any of the Championship clubs to gain promotion but the performances of Toulouse and London Broncos, in particular, in claiming two Super League scalps apiece has shaken the establishment and will ensure the Super 8s go out with a bang.
"The situation is unprecedented," said Toronto coach Paul Rowley. "Other than two of the teams, anybody can finish in any position so it's brilliant for the game.
"It's ironic that the middle eights are getting scrapped after such excitement but it is what it is.
"Winning all your Championship games and a Super League game previously guarantees you home advantage in the Million-Pound Game.
"There are that many permutations but you just have to win your games, it's simple really. We've approached every game with that mindset and we'll do the same this week."
Leeds are virtually safe after winning five of their six matches so far but Rowley is not expecting an easy ride from Kevin Sinfield's men.
"Kevin's in charge and he's a winner.," Rowley said. "He's the ultimate professional so, while we're preparing to win, Kevin will give nothing less than that.
"Leeds play fast and aggressive. We learned a little bit against Salford, where we weren't physical enough and we got beat in that area but we smartened up a little bit for the Widnes game so we've improved in some areas.
"It's a dangerous fixture but, given the inconsistency that they've had throughout the year, it's an exciting fixture as well. We're looking forward to it."
Meanwhile, the four Super League semi-finalists will all be in action on Friday night in the final round of the Super 8s.
Third-placed Castleford go to St Helens seeking their first away win of the summer era against the league leaders.
The Tigers have undertaken 31 visits without success since they defeated Saints 12-8 in the Regal Trophy at Knowsley Road in 1992 and they suffered a 46-6 mauling at the Totally Wicked Stadium in the opening game of the 2018 season.
But Castleford are on a roll with five consecutive victories and Friday's game could be a Grand Final dress rehearsal, although Wigan, who host Hull, and Warrington, who visit Wakefield, will have other ideas.
The Tigers will be without their captain Michael Shenton because of a knee injury while Saints are boosted by the return of their skipper, James Roby, who has sat out the last three games.
Wakefield are set to give a debut to teenage forward Lewis Wray.
