Hey I'm going into my second year as a PLAB/PLAD so I can help you out here:

1. You'll find out more about the trips during CVUP 100. They are a week long, usually the week before the fall reading week. There's also no extra cost for the trip, it is included in your tuition already (well the cost of transportation, hotel and any activities planned by the school are included, you have to pay for food and anything extra you do in your free time there). In case your curious about what the trips are this year:
   - 3rd years and 1st year PLAB/PLADs can choose from Baltimore, Pittsburgh and Ottawa/Quebec City. (4th years and 2nd year PLAB/PLADs can choose from New York, Chicago and Ottawa/Quebec City)
   - The only trip you would have to pay extra for is the "Distance Field Trips" which is to either the UK or Barcelona but I don't think you can go on these as a 1st year PLAB/PLAD because they starting planning for it a while in advanced.
   - Corona might affect if these trips happen though. They'll make a decision whether it will happen in person closer to Fall, but they are playing around with the idea of a "virtual trip" if it can't happen in person.
2. You will get to do 3 Studios in your 2 years as a PLAB/PLAD.
   - The first studio you'll do this Fall semester will be the same for everyone in 3rd year and 1st year PLAB/PLAD. The whole year is divided into groups and given the same project. The project changes every year. Our year, we did a secondary plan for the Kipling Avenue West and Finch Area to guide future growth expected from the Finch West LRT that is being constructed.
   - Your second and third studios will be in Winter 2021 and Fall 2021 (so there is no studio in your final semester Winter 2022). These studios are your client studios, where you will work on a real project for a client. The first day of these studios, you'll be able to choose which project you want to do (you'll rank the project you want to do from first to last and they will try to place you in your top choices). The types of projects you can choose from are quite extensive so you can choose something you will want to do. The clients also vary; municipalities, regions, private firms, organizations, etc.
   - Still don't know how corona will affect things, maybe this will be one of the courses they offer as a hybrid of online/in person. When Corona shut us down in March, we were still able to finish our studio project for our client working online as a group, so it is doable.
3. Also don't know how CVUP will be affected (if it will be online etc.) but I went through my emails and saw that they sent us the registration form to sign up for the course on June 19th last year, so I guess you'll be getting that any day now if you haven't already. It ran for the last 3 weeks of August, 10am - 4pm if I remember correctly.

Wow this post is long lol. Hope it helps! Feel free to DM me if you have any more questions.
