Opportunities like this rarely hit the market. 149 Lake Street occupies a premium, high-visibility corner at Lake & Beech St, entering downtown St. Catharines, and is now available with vacant possession. Quality commercial buildings in this location are tightly held, and when one becomes available, it does not stay available for long. Prominent, versatile and ready for its next owner, this two-storey mixed-use building offers 1975 square feet of functional space. The M1 zoning provides exceptional flexibility across commercial and residential uses, permitting professional office, retail, cafe, restaurant and similar uses, in addition to residential. It is an exceptional fit for professional owner-operators, accountants, lawyers, financial advisors, medical professionals and established local businesses, who are ready to invest in owning their own premises, rather than continuing to lease.
