Prosecutors had said that Alexandre Bissonnette's crime was so hateful and so obviously motivated by bigotry that he should receive the maximum penalty of 25 years for each of the victims the 29-year-old murdered on the night of January 29, 2017.
Leila Nasr, spokeswoman for the National Council of Canadian Muslims (NCCM), an advocacy group, told Middle East Eye that whatever the court's ruling would have been, it was "an incredibly hard day".
The January 2017 shooting, which Prime Minister Justin Trudeau denounced as a terrorist attack, provoked debate over the treatment of new arrivals at a time when Canadians were being tested by a growing number of migrants crossing from the United States into the province of Quebec.
"It's really just a day of processing what's happening and trying to find some sense of sanity in the middle of it".
Bissonnette was a known supporter of French far-right leader Marine Le Pen and US President Donald Trump.
He also told investigators he was upset with the Canadian government's plan to accept refugees and that his attack was meant to save his friends and family from Islamist terrorism.
Silver said the difference in sentences can be problematic because it leads to comparisons, such as the perception that a gay or Muslim person's murder isn't "worth" as much as that of an RCMP officer.
Justice Francois Huot chose instead to allow for the possibility of parole within Bissonnette's natural life.
She said she believes the consecutive sentencing law needs to be reviewed in order to provide more guidance for judges and avoid the harm caused by the perception of inconsistent sentencing.
Bissonnette's lawyers had argued that if he was sentenced to 25 years consecutively for each murder it would amount to death by incarceration.
He called the shooting attack premeditated, gratuitous and insidious. The defence had argued the sentences should be served concurrently, making him eligible for parole after 25 years.
"We know unfortunately in our society many people. say Islamophobia does not exist - or it's a personal act, or he had some mental illness". There were another 35 people in the mosque.
Many said they are struggling with anxiety, including one man who said he now plots a safe exit whenever he goes out to a coffee shop or a store.
Khaled Labdelli, a Montreal resident who was at the vigil, told MEE he wanted to commemorate the victims of the attack and make sure what happened is never forgotten. "I think we always have to talk about this because people forget fast".
