Thank you for contacting the Toronto Master Gardeners with your inquiry. There are a number of ways to over-winter geraniums (Pelargonium) in Toronto’s climate: cuttings, store in original container and dormant storage. One of our archived posts Overwintering geraniums gives details of each of these methods in case you would like to try a differnt method in the future.
From your description it is difficult to know if you took cuttings from your geranium or if you took them indoors and kept them growing as a houseplant. If the latter is the case, shoot tips need to be pinched back once or twice during the winter growing season in order to promote branching and to prevent weak growth. Before planting outdoors in May, make sure to fertilize them with a dilute fertilizer such as 5-10-5.
Iowa State University has an excellent article on Overwintering Geraniums
Good Luck with your geraniums.
