General Liability Insurance

This coverage addresses claims for bodily injury or property damage that occur on the shop premises or as a result of repair work. It typically responds to incidents such as a customer slipping on an oil spill in the waiting area or damage to a vehicle left in the shop overnight.

  • Cost drivers include the square footage of the facility, annual revenue, number of employees, and claims history.
  • Higher risk operations such as welding or paint work can increase premiums due to the heightened chances of fire or chemical exposure.
  • In both the US and Canada, the policy usually excludes damage to customer vehicles while in your care, requiring additional coverages for full protection.
  • Owners gain the most value from policies that include coverage for completed operations, which protects against issues arising after the vehicle leaves the shop.

Commercial Auto Insurance

Commercial auto policies cover vehicles owned or used by the business, including tow trucks, parts delivery vans, and customer cars driven by employees during test drives.

  • Key distinctions from personal auto insurance include higher liability limits and coverage for hired or non-owned autos when employees use their own vehicles for shop errands.
  • Premiums depend on the number and type of vehicles, driver records, radius of operation, and whether the shop offers roadside assistance.
  • In the US, many states require minimum liability limits that vary by jurisdiction. In Canada, provinces often mandate specific coverages through public or private insurers, with differences in no-fault systems.
  • This insurance protects personal assets if an employee causes an accident during a work-related drive.

Workers Compensation and WSIB

Workers compensation in the US and the Workplace Safety and Insurance Board (WSIB) in Ontario, Canada, provide benefits for employee injuries or illnesses arising from job duties like lifting heavy parts or exposure to fumes.

  • Employers must carry this coverage once they reach a specific number of employees, with requirements varying by state or province.
  • Cost factors include payroll totals, job classifications such as mechanic versus office staff, and the shop’s safety record.
  • In Canada, WSIB premiums are experience-rated and linked to industry classifications, while US rates are set by state rating bureaus and may allow deductible options in some states.
  • The exclusive remedy provision limits employee lawsuits in exchange for no-fault benefits, reducing the risk of large personal liability for owners.

Tools and Equipment Coverage

Specialized tools, diagnostic machines, and shop equipment often represent a significant investment that standard property policies may exclude or limit.

  • Inland marine or equipment floaters cover theft, damage during transport, or loss from fire, regardless of location.
  • Premiums reflect the total value of scheduled items, security measures like alarms and locked storage, and whether tools are taken off-site for mobile repairs.
  • Owners benefit most from agreed-value endorsements that prevent depreciation disputes after a loss, preserving cash flow for replacements.
  • Both US and Canadian insurers offer these extensions, though Canadian policies may integrate them differently under commercial property forms depending on the province.

Bonding

Bonding becomes relevant when contracts or licensing requirements demand assurance of performance, such as for fleet maintenance agreements or municipal work.

  • Surety bonds guarantee completion of work or payment to suppliers, differing from insurance because the principal must reimburse the surety for any payout.
  • Cost drivers include the bond amount, the shop’s financial statements, credit history, and years in business.
  • In the US, certain states require bonds for auto repair registrations. In Canada, provincial licensing bodies may impose similar obligations for consumer protection.
  • Bonds protect the owner by demonstrating credibility to larger clients without tying up cash in reserves, although maintaining strong financial controls is necessary to avoid claims.
