Engagement Photos - Winter

Hello everyone. We are a newly engaged couple looking to get engagement photos done for our wedding invitation that we want to send out next month. However, we are struggling to find places to have a photoshoot. Most places state that they only allow exterior shots. But it's mad cold outside and snow is falling. Can anyone suggest nice and historical/vintage places where we can take indoor engagement photos. It has to be anywhere within the GTA, including York Region, Durham, Peel, Halton and even as far as Simcoe. Thanks!
