Health Benefits for Seasonal Crews in British Columbia

Has anyone found a good solution for offering benefits to a seasonal crew? Traditional group plans seem expensive and not very flexible for our structure, so I’m currently exploring Health Care Spending Accounts instead. I’d love to hear what providers others are using for either/or and what’s worked well for your team. Any recommendations or insights would be appreciated.

For context - my business partner and I are on salary year-round for our landscaping business but 99% of billable operations, and staff are seasonal from March to December. We lay-off and try to rehire anyone who has worked in previous seasons. Goal is to have health care spending and / or benefits for ourselves as well as our staff in order to retain staff and grow the business despite the seasonality of our services (no, we do not offer snow removal or plan to go that avenue).
