Prime Minister Justin Trudeau added little Wednesday to his previous statement on Hunter Tootoo’s resignation to seek treatment for addiction issues, leaving MPs wondering whether a specific incident led to the minister’s departure.

Trudeau told reporters in Ottawa that it was Hunter’s “own choice after a very difficult situation and we will have nothing further to say on this matter.”

Conservative MP Lisa Raitt later told CTV’s Power Play that MPs are curious about why Trudeau responded differently to Tootoo’s resignation than when Liberal MP Seamus O’Regan announced he had sought treatment for alcohol issues. on Twitter at the time his “thoughts are with my friend & colleague (Seamus O’Regan) and he has my full support.”

However, Raitt said she doesn’t think the public necessarily has a right to know more about why he left.

“I think this is a deeply personal issue,” she said, emphasizing that she was speaking for herself and not the Conservative Party. “We wish him well, whatever happened.”

NDP MP Nathan Cullen said he “mostly agrees” with Raitt. “It’s so deeply personal,” he said. “There has been a difference in treatment (by the prime minister) and I don’t know why,” he added.

Earlier on Power Play, NDP Leader Tom Mulcair said that the prime minister’s comment on the resignation “evokes a situation” and “we don’t know what that is.”

Mulcair said there may be reasons to justify treating Tootoo’s issues differently than O’Regan’s, but added, “it does appear to be a contradictory position when in one case he showed a lot of empathy and in the other it was ‘hasta la vista.’”

Mulcair said he is counting on the media to find out. He also said he wishes Tootoo well and hopes the prime minister will continue “to showcase that the House of Commons is now inclusive of those First Peoples.”

Interim Conservative leader Rona Ambrose said little when asked about Tootoo’s resignation in the House of Commons. “I don’t know the details,” she said. “From what we know, I guess I would just say I hope he gets the help he needs, gets healthy.”

Green Party Leader Elizabeth May that that her “heart goes out” to Tootoo. “Get well soon and come back,” she said. “Stepping back was the brave thing to do.”

O’Regan told reporters that Tootoo has “asked for privacy and privacy is what he’s owed,” adding, “be well Hunter.”

Fellow Liberal MP Andrew Leslie, meanwhile, said he is “deeply sympathetic” to the situation, adding “I think he’s doing exactly the right thing in seeking medical attention.”

‘Lonely existence’

Asked on Power Play whether rookie MPs are prepared for the pressures of Ottawa, Raitt said it can be “pretty heady when you get here.”

“It’s not a healthy lifestyle,” she said. “You’re up late, eating at weird hours, on the road a lot.”

“Some people turn to (alcohol) as a source of coping,” Raitt added. “It’s a very lonely existence here in Ottawa.”

Cullen said that although new MPs do get a briefing, “we probably don’t say enough about … warning signs.”

“There is alcohol and there are drugs around this place, and all those tensions that are naturally going on in your life,” he added. “So be aware.”
