The league has gone through something of a revamp since its last edition. Winnipeg Hawks, who won the league last time it was held, no longer take part, while Edmonton Royals are also absent. Their place is taken by Surrey Jaguars and Mississauga Panthers. Each side will include two marquee players and three Canadian players from the national side, as well as three emerging Canadian players, with 25 matches to be played across the 18 days.

This means there will be two high-profile North American T20 franchise-based leagues this summer, after dates for the inaugural season of Major League Cricket, set to be played in Texas in July, were announced last month.

The GT20's return adds further strain on a cricketing calendar already groaning under the weight of several T20 leagues. It will clash with Pakistan's two-Test series against Sri Lanka in July, with 14 Pakistan players picked up across the six franchises. The PCB has insisted that players chosen for the Test series will not go to the GC20.

The first two seasons took place in 2018 and 2019, but following payment disputes and the Covid pandemic, a third edition wasn't held in the next three years.
