Wow, I'm away from the forum for a couple of days and my part of the world is the topic of discussion - DIngbat, I haven't checked out TGS for seeds this year - maybe their policy has changed - I ordered online last year, and grew, with very good success:
Sungold
Black Cherry
Galinas
Black From Tula
Silvery Fir Tree
Stupice
Earl's Faux
Faux Earl's Faux
Red Brandywine
Azoychka

and I grew with some success:
Brandywine Sudduth
Aunt Gertie's Gold

And I may be missing some - this is off the top of my head... Yes winter is long and cold here, but summer can be nice and you can't beat those loooong hours of daylight in the great white north.
This year I will probably be trying:

Sophie's Choice (originated in Edmonton, I
understand)
Kimberly
Druzba
Cherokee Purple
Kellog's Breakfast
Dr Carolyn
Polish (Ellis)

There are a lot of Italians in the Toronto area - there must be some good tomato gardens too!
