When you grow up working in a greenhouse, receive a diploma in horticulture, and then work as a golf course superintendent for 11 years, one thing is for sure—you love green spaces.

When Laura Breeze and her family moved from New Zealand to Calgary in 1977, landscaping was the furthest thing from their minds. Laura was a nursery school teacher, and husband Rex worked as a building operator for a property management firm. When the firm's maintenance contractor failed to show up one week, Rex's boss asked if he knew someone who could mow the lawn. Laura volunteered, and she's been mowing ever since.

For Liz and Grant Monette in Guelph, Ontario and Bessie and Mike Krsovan in nearby Waterloo, being married is more than sharing a life, it's sharing an occupation, too. Both couples operate landscaping companies.
