Mono bouquets in Toronto: what one flower in one colour says in Canada
Mono bouquets in Toronto are chosen by colour first. In Canada the chrysanthemum is a funeral flower of respect, not a taboo, and white is the traditional funeral colour, so a single-variety chrysanthemum bunch leans on that colour rather than the flower itself. A mono bouquet has no other stems to soften the reading, which is exactly why colour decides what the bunch says before the flower does.
Chrysanthemums in Canada: a flower of respect, not a taboo
A white chrysanthemum at a Canadian funeral signals respect, and the flower sits alongside lilies, roses and carnations as one of the varieties most often chosen for that colour. Chrysanthemums make up one of the widest sections among the city's mono bouquets, which on its own says the flower is bought for far more than mourning.
That width is the useful part for a buyer deciding what to send. A single white chrysanthemum bunch, nothing else in the wrap, reads as condolence because the colour carries the meaning on its own. Choose a bright shade instead, coral, yellow, burgundy, and the same flower becomes a birthday or a thank-you, since nothing in a one-variety bouquet pulls the eye toward a funeral palette. The colour decision, in other words, comes before the flower decision.

White lilies, carnations or chrysanthemums for a Toronto condolence
Lilies, roses, carnations and chrysanthemums are the flowers most commonly sent to a Canadian funeral, and white is the shade that keeps them unmistakably that. The section carries white lilies as well as chrysanthemums, so either gives the same clear signal in a single variety and colour.
Canadian custom draws a line between the two kinds of flowers a death brings. A formal arrangement for the service itself goes to the funeral home, while a bunch meant as condolence is sent to the family at home, a distinction worth keeping in mind before choosing where the courier takes it.
Jewish custom runs differently again: flowers are not sent to the funeral or during the week of shiva that follows. The usual gesture there is a basket of fruit or kosher food rather than a bouquet of any colour.

Gerberas, tulips or hydrangea when the news is good
For good news, one bright colour is what moves a mono bouquet away from anything white can suggest. A bunch of gerberas in a single shade, coral, yellow or pink, does that cleanly and wrapped in kraft paper reads as a plain, cheerful gift rather than a gesture tied to any custom.
Tulips form the widest single-flower section in Toronto's mono bouquets, so a seasonal colour is nearly always on hand. Hydrangea works differently: its heads are large enough that only a few stems already make a full bunch, which is why a bunch of pink hydrangea holds its shape without needing many flowers at all.
The dates worth watching for a Toronto bouquet, and the flowers that come and go with the seasons, are on the flowers in Toronto page. Each mono bouquet is put together once the order is placed, and the florist photographs it before the courier leaves; most orders go out the same day they come in, with everything else on the delivery details page.
A white chrysanthemum or a white lily bunch is the surer choice for condolences, while hydrangea or a bunch of gerberas in a strong colour fits a birthday or a thank-you without raising any doubt about the occasion.
