The reasons Canadians give for not having a will are familiar and human: it's uncomfortable, it's expensive, it can wait, I'm too young, I'll do it when things settle down. These reasons have enough psychological coherence to feel valid while concealing the full cost of inaction. A Canadian who dies without a will does not get to choose. They get the provincial intestacy formula - a statutory distribution scheme written for an idealized family structure that increasingly bears no resemblance to actual Canadian families, which include blended families, common-law partners of decades, estranged relatives who are still legally next of kin, and children from multiple relationships.
The common-law partner trap is the most devastating intestacy outcome in Canada. In most Canadian provinces, a common-law partner - someone you may have lived with for 20 years, built a home with, raised children with - has zero automatic inheritance rights under intestacy legislation. If you die without a will in Ontario, your common-law partner of 15 years receives nothing from your estate as a matter of law. Your blood relatives - parents, siblings, nieces and nephews - may be entitled to your entire estate while your partner lives in the home you shared. This is not an edge case. It is the standard outcome for a very large and growing number of Canadian families.
