Fehr, who cleared waivers earlier in the day, has six goals and 11 points in 52 games this season. The 31-year-old is signed through the 2017-18 campaign, earning $2 million per season.
A 12-year NHL veteran, Fehr brings size and playoff experience to Toronto. The six-foot-four, 212-lb. winger has played in 60 career post-season games, including 23 last season when he won a Stanley Cup with the Penguins.
He’ll join forward Brian Boyle, who Toronto acquired this week to help with its push for a playoff berth.
Oleksy, 31, is in his fourth season in the NHL. He appeared in 11 games for Pittsburgh this season and has just 62 career games under his belt (three goals, 19 points, plus-15).
The 23-year-old Corrado played just two games for the Maple Leafs this season and 39 in the 2015-16 campaign. The Toronto native was drafted in the fifth round (150th overall) by the Vancouver Canucks in the 2011 draft and was claimed off waivers by the Maple Leafs in October 2015.
