According to NCA Newsire's Marc McGowan, Williamson's agent, Liam Pickering, was seeking opportunities for his client after leaving Princes Park, and recently reached out to North's GM of football, Brady Rawlings.
The agreement, however, does not stipulate that Williamson will be afforded a spot on North Melbourne's AFL list.
Carlton released the following statement after Williamson departed Princes Park earlier this season:
"As a result of these discussions, it has been mutually decided that Williamson will step away from AFL football for 2022 and depart the football club," Carlton's statement read.
"The club will continue to work with Williamson, the AFLPA and Williamson's management to ensure he continues to receive the necessary support he needs moving forward."
The North Ballarat Rebels product played 44 AFL games in navy blue after being drafted by Carlton in 2016.
