LAC-MEGANTIC, Que. -- Hours after a solemn procession passed the spot where tragedy struck Lac-Megantic a year ago Sunday, crowds packed Ste-Agnes Church to remember the 47 people who perished when a runaway train derailed in the centre of town and exploded.

First responders who plunged in to fight the inferno that erupted after the train jumped the tracks were given a resounding round of applause when they entered the church Sunday in long lines.

Framed photographs of the victims were on display alongside bouquets of flowers at the front of the church, which sits not far from the crash site. In a poignant, personal touch, a baseball glove lay in front of one man's photo.

"How many times has the whole community of Lac-Megantic impressed us, by its wisdom, and its capacity to lift itself up?" said Archbishop Luc Cyr, who presided over the service.

"You have given us a beautiful message of dignity and strength. Yes, there have been tears and great suffering but at the same time there has been overwhelming generousity and love."

Some of those tears were being shed Sunday by people gathered outside the church to watch the service as it was projected onto a big screen metres from the derailment site. Some sat on lawn chairs and dabbed at their eyes.

Parish priest Steve Lemay told the service that it has been a difficult year and he urged the polticians present to continue to provide support for the community.

"I pray and I will continue to pray for the fraternal support you offer us today will continue in the form of concrete decisions and actions.

"We still need help to rebuild our town and protect our environment."

The Sunday service was the latest commemoration in a weekend of events to remember the tragedy. A moment of silence followed the ceremony and a monument to the victims in the form of a large granite book with their names inscribed was dedicated on the church's lawn.

Dignitaries including Gov.-Gen. David Johnston and Quebec Premier Philippe Couillard lay bouquets of flowers in front of the monument and attended the church service late Sunday morning.

Prime Minister Stephen Harper marked the first anniversary of the tragedy in a statement, noting the "resilience, determination and extraordinary strength of character" of Lac-Megantic residents.

"No passage of time can erase from our consciousness the lives lost, the injured and the families torn apart by this tragedy," Harper said.

"Having witnessed this first-hand during my visits, I owe these people my greatest admiration," said Harper, who was represented at Sunday's ceremony by International Development Minister Christian Paradis, who is also the local MP.

Johnston offered renewed condolences and hopes for a brighter future for all in Lac-Megantic.

"The town will rise again, from the solid foundation of resilience and compassion laid by its people," Johnston said Sunday in a statement.

Johnston also announced that he is presenting the Commendation for Outstanding Service to the first responders and citizens of Lac-Megantic and the surrounding communities, "as a way of recognizing their extraordinary efforts and exceptional kindness and caring."

Earlier Sunday morning, more than 1,000 people marched in solemn silence in the darkness after observing a moment of silence at 1:15 a.m. That was the exact moment on July 6, 2013 when the fuel-laden train derailed and exploded in a series of cataclysmic fireballs.

Though a year has passed, the emotional scars in the community remain as deep as the physical damage that is still so apparent on the local landscape.

The march followed a midnight mass and a moving speech by Mayor Colette Roy Laroche, who received two thunderous rounds of applause and two standing ovations from about 1,200 people who packed Ste-Agnes Church.

"For several minutes we tried to convince ourselves that it wasn't true," Roy Laroche said of the July 6 catastrophe in a speech also watched by about 200 people on a big screen outside the building.

"But what happened to us was a nightmare. When we removed our hands (from our eyes), the horror was still there and the worst was to come."

She urged townsfolk to turn the page on the tragedy and look to the future, but to never forget.

Roy Laroche, who became a household name in Quebec for her leadership and poise in the disaster's aftermath, also asked the community to stick together to overcome any future obstacles.

"A year ago, we found ourselves in one of the worst tragedies in the histories of Quebec and Canada," she said.

"We were also covered by the biggest wave of love and solidarity that modern Quebec has ever known."

In his sermon during Sunday's midnight mass, Rev. Steve Lemay, the parish priest, offered words of comfort.

"There's still more road to cover," said Lemay, who presided over many of the victim's funerals and has opened up about how hard the year has been on him.

"Many of us are still suffering from the consequences of the catastrophe that struck us . . .

"We have suffered and cried together, we worked together, walked together and it's together that we will continue on the path."

Many participants in the march wore glowing plastic stars on their chests. Several wiped away tears as they held hands with the person next to them.

Most stared sadly at the downtown area where dozens of buildings were gutted. To this day the zone remains off-limits behind metal fences as decontamination work continues.

A half-dozen people left the march to sit side-by-side on the railway track, looking at their broken town.

Nearby a woman stood by herself, gazing in the same direction while weeping quietly in the darkness.

"I think it was important to do this to complete our mourning process," said walker Bernard Boulet, whose sister Marie-France was declared dead in the disaster, though her remains were never found.

She lived in the downtown area that was incinerated by the explosions. Boulet said several of her family members took part in the events.

"It does us some good," Boulet said of the mass and the march.
