Your letter to the bugman: There were many of these bugs last summer. I’ve never seen them before. They were near my blazing stars, wild geraniums, clematis and lilies. They are not the same as the bugs that attacked my lilies the year before.
How you want your letter signed: Dying to know.
Firebug
Dear Dying to know,
This sure looks to us like a European Firebug, Pyrrhocoris apterus, a species that has been introduced to North America, but according to BugGuide, there are only reports from Utah. If it has also become established in Canada, you should probably notify your local agricultural agency.

I also have tons of these pop up recently. I also live in Brampton. What is the best authority to notify?
We just verified on iNaturalist that Firebugs have indeed been reported from Ontario. Try reporting to the Invasive Species Centre.
I live in Brampton and also have firebugs in my garden. First year I have ever seen these
