The Raptors will bring a contingent of five members of the organization to meet with Steve Nash as soon as he's ready on Sunday.
Toronto's offer, likely to reach $12 million per season according to sources, is likely to be the most lucrative.
The Raptors are pushing for a playoff return in the 12-13 season.
"The Raptors would be one of those teams where you're probably not going there to win a championship in the next three years," said Nash. "For me it'd be going home to Canada, to a great city, and trying to help an organization move forward.
"I'm open to the positives of all of them. It'd be great if four or five contenders came after me and all offered me a deal, but the reality is I might not get that opportunity. So I'm going to look at every opportunity and Toronto will be one that I'll study as well and look at the opportunity for them to grow in the next three years and what kind of impact I can have on that team. And obviously from a community standpoint, it's a special place for me."
