Will my union dues and membership just continue automatically?

If you're in a unionized workplace, the general answer is that your union membership and the collective agreement covering you don't simply evaporate because the business was sold — Ontario labour law is built around the idea that a sale of a business generally doesn't, on its own, wipe out existing bargaining rights or the collective agreement, particularly where the new owner continues the same operation.

In practice, this means dues deduction and membership typically continue, and the new owner steps into the position of employer under the existing collective agreement, at least for a transition period, rather than the union simply losing its standing overnight. The details of exactly how a sale affects bargaining rights, and whether anything needs to be formally addressed with the labour relations board, can get technical, and your union's own representatives are usually the fastest and most reliable source of a precise answer for your specific situation.

If you haven't heard anything from your union about the sale, or dues suddenly stop being deducted without explanation, raise it with your union representative right away rather than assuming it's a routine administrative gap.
