The Haliburton Highlands Chamber of Commerce says almost 200 jobs could be at risk.
This is according to a study done on the impact of changes to Bill 148, which includes raising the minimum wage to $15 Â an hour by 2019.
The chamber report says 30 jobs could be lost in the accommodation and food business, as well as another 30 in the construction industry.
The study done by the Canadian Centre for Economic Analysis says 185,000 jobs are at risk province-wide.
Chamber President Richard Wannan said he is in favour of seeing the minimum wage increase but 32 per cent in  18 months is too much for many businesses in the county to handle.
