KITCHENER Every spring, Canada geese can become very territorial. Guelph Humane Society Associate Director Lisa Veit says that s because late March to late April is considered nesting season in Canada. “They can be quite aggressive and this is really the efforts of the birds to defend their nest, she said. The humane society has been receiving increased calls recently from residents complaining and asking questions about the birds. Veit says the best thing to do is give them extra room for about a month, describing it as “a small inconvenience.” “This is a great opportunity for us to practice some patience and tolerance with the wildlife that we share our community with, she said. They need their space.”
