My wife and I found a weekend we can get away from the kids, and decided to pull a city out of the hat that we can drive to. Toronto won. We’ve never been, we expect it to still be cold as hell, and we have no idea what we should make sure we see or do. Any suggestions out there?
Do a bagel tasting tour. I’ve read Toronto bagels are unique and not to be missed.
It’s hard to say because they shut the city down again. Things are supposed to start reopening next week but depending when in March you arrive there will be different levels of reopening.
When I’ve gone to Toronto I’ve:
Visited friends
Gone square dancing
Gone to a meeting of the casualty actuarial society
Shopped colleges for my son.
I think i went sightseeing there as a small child, but i don’t remember what we did, and i assume stuff has changed. So…i guess i can’t help. Except it’s an attractive big city. You can walk along the streets, buy poutine from a street cart, go to museums, eat at restaurants… I don’t tend to go to sporting events, but they have a couple of big league teams that compete with US teams.
Depending when in March you go. There could be a winter blizzard, or it could be very spring-like. Luck could be a factor.
All my recommendations are made with the disclaimer that I don’t know what will be open/closed at that time due to COVID.
I strongly recommend you don’t miss going up the CN Tower.
Museums, you might check out: the Royal Ontario Museum, the excellent George R. Gardiner Museum of Ceramic Art across the street, and the Art Gallery of Ontario. There’s also the Bata Shoe Museum.
Fort York, an old installation of the British and Canadian military, is well worth seeing for those who like that sort of thing.
There are also various things to see/do around Harbourfront/the shore of Lake Ontario.
If you feel like shopping, you can’t go wrong with the Toronto Eaton Centre, or you could go uptown to the big Yorkdale mall.
If there’s anything specific you like to get out of a tourist trip, let us know and I’ll see if I can’t give you another suggestion or two.
Huge disclaimer: covid could throw any of this into meaninglessness. Also, I haven’t been to Toronto for two years because of covid, so there’s probably a lot I’m missing.
March is kind of early for touristing… the winter festivals are over, spring things have not yet begun, it’s the dregs of winter, and the city can be grey and depressing. Still, it’s not as depressing as November. Early March vs. late March makes a big difference; in late March there’s a good chance of springlike conditions.
Where are you coming from? If you plan to drive around the city, be aware that there is a lot of construction going on, even now. The hundreds of skyscrapers going up… subway/ light rail/ heavy rail construction in at least three places (across Eglinton Ave for Line 5, various places around the city for the Ontario Line, out in Scarborough for the Line 2 extension, various places around the city and beyond for GO regional rail expansion, across Finch Ave west for Line 6… okay, that’s more than three…)
More tips… don’t pass streetcars on the right when their doors are open… Yorkdale Mall is the fanciest/ most upscale mall in the city, more so than the Eaton Centre… assume it takes about an hour to get anywhere… avoid any toll highways unless you want to pay out the nose for travel; Highway 407 and its ilk charge up to 50c/km, and if you don’t have a transponder, they take a picture of your license plate and tack on an extra fee… and don’t think that being out-of-province will save you; they have agreements with many other provinces and states…
As a Toronto Jew, I’d say you are better off in Montreal for this. Bagel World for a twister, Gryfes for a regular bagel and you are done. The rest are either Montreal style or buns with holes.
I’ve only done the first of these 
March weather is highly variable, it could vary 20 degrees C through the course of the day and be sunny, rainy, or snowy.
If you are foodies, St. Lawrence market (traditional indoor market) and Kensington Market (outdoor district) are worth a visit.
Thank you all for your suggestions. We’re now slightly worried about another lockdown, but we’ll figure it out. Keep the suggestions coming!
Man, I sure hope this will still be going on! 
Make sure to wear your Sunday finest. It would be a causality to dress casually to the actuarial society, actually.
Given the current political environment here with a provincial election in a little over 4 months another lockdown is unlikely unless the next variant causes bleeding from all bodily orifices.
Indoor dining and entertainment just reopened in Ontario on Monday. As long as you are fully vaxxed and mask indoors, you shouldn’t face any issues.
Remember you need a NAAT test, not antigen test, and upload vaccine card and test results in the ArriveCan app before you hit the boarder (I assume you are USAian).
