Politicians of all stripes put partisanship aside to express their grief over the loss of Conservative MP Gord Brown, who died suddenly in his Parliament Hill office on Wednesday at the age of 57.

Wednesday afternoon, MPs gathered in the House of Commons to pay tribute to Brown before observing a moment of silence and adjourning for the day. Online tributes are also pouring in from across the political spectrum.

Prime Minister Justin Trudeau called Brown a 鈥済reat guy,鈥� who was 鈥減articularly good at transcending the partisanship here, and really emphasizing the service, not just to our constituents but to all Canadians.鈥�

Conservative Leader Andrew Scheer, who was first elected in the same year as Brown, reflected on his late colleague鈥檚 career, reputation, and contributions, as tearful MPs looked on.

"He was an eternal optimist who was always quick with a compliment or a supportive word," Scheer said.

Ahead of, and following the remarks in the House of Commons, MPs from all sides expressed their grief, and his death had many reflecting on the work-life balance of parliamentarians.

"We all keep having these conversations over and over about this concept of work-life balance in politics and you know, focusing on family and friends and people who are going to be in your lives once your political endeavours are over. And days like today make you really think long and hard about that," said Conservative MP Shannon Stubbs.

"I don't know that we're all necessarily the best at taking that advice or living in that way, but Gord's passing, I think, has us focused on that today," she said.

International Trade Minister Francois-Philippe Champagne said he was just walking with Brown yesterday. "It reminds us that everyone is precious," he said, before getting emotional and walking away.

"This job, I鈥檓 not trying to be morbid, but it鈥檚 a death trap for people sometimes鈥� It takes years off your life, and I know we do it willingly but sometimes the price is very high," Conservative MP Tony Clement said. "He鈥檚 just a good man鈥� I鈥檒l miss him every minute of every day."

鈥淲hat an incredible person, and you know, it鈥檚 a reminder of how fragile life is, and I hope everyone who hears the news will hug the people close to them, and their family, and be kind to one another,鈥� said Indigenous Services Minister Jane Philpott.

Meanwhile, many more have taken to social media to express their condolences.

Former Prime Minister Stephen Harper said on Twitter that he and his wife Laureen were 鈥渟hocked and heartbroken鈥� to learn of the loss.

鈥淐ollegial and always smiling, Gord's absence leaves us all with a tremendous void,鈥� Harper wrote.
