Pretty clearly a yes. It's a shame the NHL hasn't done more for him the way MLB has done for Jackie.
Although, I don't think the NHL has had such a history of clear racism and segregation as MLB, there just aren't that many non-white hockey players due to a number of other factors (geography, cost of entry, etc). However, he clearly deserves to be honored.
It helps that Jackie Robinson was a tremendous player for a pennant winning team in New York City, while Willie O'Ree had a short NHL career for a team that finished bottom in his only semi-full season.
The NHL has its history of racism, it's just shrouded by Canada's lack of non-white people before the 70s. Larry Kwong certainly didn't get his chance, nor did Herb Carnegie. The Coloured Hockey League in Nova Scotia were innovators and toiled in relative obscurity until the league folded in 1930. It took until 1949 for a Native player to stick in the NHL (George Armstrong), were there Native players good enough to have careers before then? Probably.
Shit, the league wasn't even that friendly to white people who weren't Old Stock Protestants. The Winnipeg Falcons faced discrimination for being Icelandic and French-Canadian players have most certainly faced discrimination.
MLB's discrimination was more obvious, since people knew in the 19th century that 12% of the population could play ball as well as the other 88%, and society didn't fall to pieces when Jim Thorpe, Albert Bender, John Meyers, etc., all Natives, played in the majors.
