If you wish to continue in business, you will be considered a new entity beginning on the day after the assignment into bankruptcy. You will require a new business number (BN) for your new CRA accounts.
When a partnership comprises of two individuals and one declares bankruptcy, the partnership can no longer exist.
When a partnership comprises more than two individuals and one declares personal bankruptcy, the partnership may continue to operate, further to an agreement between parties involved. For example, a law firm of 100 partners may have one partner that has declared personal bankruptcy and the law firm is not liable for the partner's personal debts. The law firm may continue in business despite the partner's personal bankruptcy.
In most cases, unless a bankrupt corporation pays all debts owed at the time of bankruptcy, the company ceases to exist.
If you wish to dissolve or start a new incorporated business, you will have to contact the government body that governs the affairs of your corporation.
