With the 100th Grey Cup just a few days away, the buzz is building in downtown Toronto.

Calgarians have flooded into the city, bringing some Western flare with them, complete with boots, hats and a horse -- albeit one borrowed from Ontario as an honourary mascot for the Stampeders, who face off against the Toronto Argonauts on Sunday.

Following are some key Grey Cup-related events taking place in the city on Friday afternoon:

  • Riderville: 2 p.m. to 1 a.m. at the Metro Toronto Convention Centre

Although the Saskatchewan Roughriders aren't in this year's Grey Cup, their fans are here. Riderville is a home away from home for the green army. Essentially, this event is a party celebrating all things Saskatchewan -- and everyone's invited. Saskatchewan talent Wonderland, the FOXX WORTHEE and Tongue Jungle will perform. Tickets: $20 at the door

  • Lions Den: 4 p.m. to 1 a.m. at the Metro Toronto Convention Centre
