MONTREAL -- One of Canada's best-known religious landmarks, the Notre-Dame Basilica in Montreal, is seeking urgent government assistance to withstand a budget shortfall caused by COVID-19.

Claudia Morissette, director of the historic church in Old Montreal, said Notre-Dame expects to be short about $12 million in revenues this year as cultural events and guided visits remain suspended due to the pandemic.

"It's huge. It represents 85 per cent of our total revenue," Morissette said in an interview.

She said that money is "absolutely necessary" to preserve and restore the stone church, which was constructed in the 1820s in the Gothic Revival style and remains one of the main tourist destinations in the city, welcoming around one million visitors per year before the pandemic.

A first phase of restoration work is already underway on its facade, but Morissette said the church is concerned it will not be able to finance the second and third phases of restoration on the building's east and west towers.

These first three phases are expected to cost $9.2 million out of a total of nearly $30 million of work needed to preserve and restore the building over the next decade, the church estimates.

"We can't press pause (on phases two and three) because that would risk putting the integrity of the towers in peril and (could) even become dangerous," said Morissette, adding that delays on the work could also lead to an increase in overall costs.

Notre-Dame is not the only church in Quebec facing economic challenges due to COVID-19, which has hit the province hard.

Across the province, where the Catholic Church historically played a central role but has seen a decline in recent decades, many churches have struggled to pay rent and maintain their aging buildings as the pandemic forced them this spring to suspend in-person services.

Quebec's Culture Department announced last month that it would invest $15 million to preserve religious heritage, targeting 62 buildings and three organs. Culture Minister Nathalie Roy said the investment also would help stimulate the economy and create jobs for artisans and labourers.

Morissette said Notre-Dame received $1 million last year from Quebec's Religious Heritage Council, a non-profit organization that supports the conservation of historic buildings, to help finance part of phase one of its restoration. But the church did not get any of the new funding.

"We understand that (the money) goes quickly, and we also understand that we're not the only ones. We know that COVID-19 affected many people," Morissette said. "But we're a major attraction. We are one of the major patrimonial jewels."

The Quebec Culture Department did not immediately respond to a request for comment from The Canadian Press.

Andreanne Jalbert-Laramee, cultural heritage adviser at Quebec's Religious Heritage Council, said that if Notre-Dame is struggling, smaller and less renowned churches are no doubt struggling, too.

"The worry is that if their financial situation is difficult, they will delay these restoration projects, this work, and that will make the situation even more difficult for those buildings," Jalbert-Laramee said in an interview.

She said that while about $40 million is needed to restore and preserve religious heritage buildings across Quebec, the government's $15-million investment is a good step.

"These are interventions that are essential for the survival of these buildings," Jalbert-Laramee said. "We see that the need is great, the need is there."

For her part, Morissette said she remains concerned the Notre-Dame Basilica will not be able to finance its restoration.

While daily masses resumed last month, guided tours and shows that draw tourists to the church have not -- meaning that Notre-Dame missed out on the summer tourist season, which typically draws hundreds of thousands of visitors.

The church said it sold nearly 833,500 tickets for guided tours and over 227,000 tickets to its light show called Aura in 2018.

Morissette called for any of the three levels of government -- federal, provincial and municipal -- to provide urgent financial aid to help Notre-Dame withstand its losses.

"Because it's the symbol of the founding of the City of Montreal, that it's one of the most well-known religious monuments in North America, that it's the main tourist attraction in Old Montreal ... we need to preserve this gem so that the next generations can enjoy it," she said.
