The unrestricted free agent played in 48 games with the Blue Jackets last season, registering 12 goals and 18 assists for 30 points.
According to Dan Murphy of Sporstnet, who first broke the news via Twitter, the Canucks' AHL affiliate, the Utica Comets, are going to sign Prospal to a professional tryout contract, upon which the Canucks can decide if they want to sign him to a deal.
"Our intent is to sign him to a PTO, he can't play without signing one," Canucks assistant GM Laurence Gilman told Murphy.
The Canucks have been looking for depth on the wing for some time, and could have some a short-term solution without having to give up an asset via the trade route.
Prospal skated with the Comets today and could make the jump back into the NHL shortly.
"Based on our injury situation, and not sure what the future may hold, it was an option worth looking at," Canucks GM Mike Gillis told Murphy.
In 1,108 career NHL regular-season games with the Philadelphia Flyers, Ottawa Senators, Florida Panthers, Tampa Bay Lightning, Anaheim Ducks, New York Rangers and Blue Jackets, Prospal has accumulated 225 goals and 510 asists for 765 points.
Prospal was originally drafted by the Flyers in the third-round (71st overall) of the 1993 NHL Entry Draft.
