On December 20, 2024, the Tax Court of Canada ruled on a case involving a married couple who claimed losses from two ventures: a dog breeding business and short-term vacation rentals in British Columbia’s Okanagan region. The activities spanned the years 2004 to 2010, with dog-related losses dating back to 1999.
Dog Breeding: Not a Business
Despite the couple’s passion and intent to earn income through breeding champion dogs, the Court found the operation lacked commercial viability. Over 20 years, they incurred nearly $1 million in losses with less than $50,000 in revenue. Key issues included:
- Poor financial planning and reliance on credit cards
- Inadequate budgeting and recordkeeping
- Limited marketing and sales efforts
- Expert testimony confirming the activity was not commercially reasonable
The Court concluded the dog breeding was more personal pursuit than business, and denied the losses.
Vacation Rentals: A Business Venture
In contrast, the couple’s short-term rental activities were deemed commercial. They had researched market viability, obtained proper insurance, hired help, and adapted their strategy over time. Though early years showed limited income due to wildfires and repairs, later years were profitable. The Court allowed the rental losses, recognizing the businesslike approach.
Statute-Barred Returns and Reassessment
CRA reassessed some years beyond the usual three-year limit, arguing misrepresentation. The Court disagreed, finding the couple had a genuine belief their activities were income-generating, supported by professional tax advice. However, clearly personal expenses claimed due to poor tracking were disallowed.
Ensure your business or rental activities are conducted in a commercially reasonable and well-documented manner to support loss claims and avoid disallowed deductions.
