Would $300,000 combined with a $200,000 loan be enough?

I'm looking to purchase a Tim Hortons franchise in Vancouver, BC, Canada. I have $300,000 but I still need about $200,000 to meet Tim Hortons requirements (up to $480,000 not including tax). I was hoping to get a loan from the Canadian Small Business Finance Program to support me. Is this possible? Will it be enough? Thanks!!!
