Thousands will converge on North York Sunday night to remember the victims of Monday's van attack.
An estimated 25,000 people are expected to attend a vigil at Mel Lastman Square for the 10 victims starting at 7 p.m.
Among the dignitaries expected to attend include Prime Minister Justin Trudeau, Ontario Premier Kathleen Wynne and Toronto Mayor John Tory.
Significant road closures are in place for the vigil and Tory, speaking to Newstalk 1010's Dave Trafford Sunday morning, urged those wishing to attend the vigil to use public transit.
"Any attempt to drive would be just unwise because we are expecting a very large crowd and the streets will be closed around there for various points in time and so people please, we want them to come very much, but please take transit."
Those wishing to attend can access the vigil via TTC subway with stops at Sheppard, North York Centre, or Finch stations.
The memorial around the site of Monday's tragedy has grown daily. Tory admits he's been moved by the countless tributes people have left there.
"It's an extraordinary thing because not only have people left flowers, I'm not exaggerating when I say thousands of bouquets of flowers. But they've left little notes on pieces of bristol board that are there and the notes are in every language you can possibly imagine and they're just very moving to read."
The Ahmadiyya Muslim Jama`at Canada has announced it will be in attendance at Mel Lastman Square for most of the afternoon and evening. A total of 1,000 members of the community will be offering special prayers and distributing thousands of flowers. Additional groups that will be there include the Toronto Jewish Chorus, the Red Spirit Drummers and the Metropolitan Community Choir, among many others.
