I am struggling with both isolation and togetherness- when this started I offered for my boyfriend to stay here thinking it would be a couple of weeks. He was still going to the office everyday and I didn’t want him taking the train (from my place he can walk) and risking himself and even more his parents who live with him and are in their 70s. So now we are both working from home most days (he still goes in once a week) in my tiny apartment. It’s going better than I would have thought, but my daily runs (alone) and the days he goes to the office being alone is delightful. At the same time I am missing my wider social circle- I have regular video chats but it is just not the same! I am hoping we can arrange a picnic sometime soon with a few people and keep our blankets 6 feet apart.
If you are staying downtown, or near to a subway stop, I would reconsider the rental car. Driving in Toronto is awful - too congested and too many aggresive drivers. Pretty much everything to see as a tourist is downtown, and easily accessed by foot, or TTC. And in the downtown area, it's often faster to walk than drive short distances, or grab a bixi (bike share). I'm in Toronto, send me a pm if you want some suggestions of stuff to see and places to eat.
