"Playoff Officiating" cost the Canucks two Stanley Cups.
In 2011, definitely. That, along with injuries. Nashville, San Jose, Boston, and Philadelphia were the 4 most physical teams that year, and we ended up playing 3 of those teams.
In 2012, the only team that was capable of stopping us under a full healthy roster was the team we played in the first round that year (and for the first few games, we were without Daniel).
Games 3, 4, and 5 against the Bruins in 2011 were an absolute joke.
Ironically enough, Game 5 was one of the worst officiated and biased games in NHL history and yet the Canucks managed to win 1-0 somehow (thanks to some off-the-charts defensive play and goaltending). To Boston's credit however, Games 6 and 7 were called fairly evenly (my guess is that after the Boychuk hit on Raymond, the refs decided that enough was enough, in terms of getting back at the Canucks' for Burrows' antics).
Games 4, 5, and 6 against Chicago in 2011 were also incredibly biased, since Pat Kane and Jonathan Toews are the NHL's 'darlings' (2nd fiddle to only Crosby).
However - the series' against LA in 2012 and San Jose in 2013 takes the cake in my view.....especially the San Joe 2013 series. Any attempt at the Canucks playing a physical style was penalized right away, whereas LA and San Jose were pretty much allowed to run amock (which then gave birth to the notion that the Canucks were being physically man-handled).
I didn't have too much of an issue with the Calgary series in 2015, but did find it strange that Michael Ferlund was allowed to take 4-5 strides towards a Canuck player in an attempt to belt him. #Charging?
My guess is that the Canucks were being punished against Boston due to the refs mishandling of the Burrows' situation in Game 1. I suspect that the LA and San Jose series' in 2012 and 2013 were officiated in that way to punish the Canucks for their diving in 2011 (I will concede that they dove quite a bit in 2011), along with possibly punishing the fans' for rioting. That's the only explanation I have for such terribly biased officiating during those years.
