Longweekend shows and events?

Hi Everyone
The family is perhaps heady down to the Southern Ontario ( Toronto) , Niagara and all points in between this up coming long weekend. My wife suggested my son and I get our selves lined up for any kinda train show going on over the long weekend as her and my daughter want to go shopping.
Can anyone tell me of any events going on over the long weekend? Also I was told from a railroder hobbiest at one time that there’s sometimes Layout tours that go on over the weekend somewhere down in Sothern Ontario I’d sure like some info on that if its available.
Thankyou
