What Makes the Difference In Law Between a Renovation and a Demolition?
Renovation Is When a Unit Capable of Habitation Will Exist When the Work Is Done.& Demolition Is When a Habitable Unit Will No Longer Exist.
The law provides that a tenant holds the right to return to a rental unit following a renovation to the unit previously occupied by the tenant but not following a demolition. Accordingly, this right raises the question as to what extent of construction constitutes a renovation and what extent of construction constitutes a demolition. The short answer is that following a renovation, there will be a rental unit capable of being occupied; but, following a demolition, a rental unit capable of being occupied will no longer exist.
The Law, statutory
Firstly, it is necessary to appreciate that the tenant, per s. 50 of the Residential Tenancies Act, 2006, S.O. 2006, Chapter 17 may provide notice to the landlord, upon receiving notice from the landlord of an intent to do repairs or renovate, of an intention to return and occupy the unit following the repairs or renovation. Specially, s. 50 of the RTA states:
50 (1) A landlord may give notice of termination of a tenancy if the landlord requires possession of the rental unit in order to,
(a) demolish it;
(b) convert it to use for a purpose other than residential premises; or
(c) do repairs or renovations to it that are so extensive that they require a building permit and vacant possession of the rental unit.
(2) The date for termination specified in the notice shall be at least 120 days after the notice is given and shall be the day a period of the tenancy ends or, where the tenancy is for a fixed term, the end of the term.
(3) A notice under clause (1) (c) shall inform the tenant that if he or she wishes to exercise the right of first refusal under section 53 to occupy the premises after the repairs or renovations, he or she must give the landlord notice of that fact in accordance with subsection 53 (2) before vacating the rental unit.
Earlier Termination by Tenant
(4) A tenant who receives notice of termination under subsection (1) may, at any time before the date specified in the notice, terminate the tenancy, effective on a specified date earlier than the date set out in the landlord’s notice.
(5) The date for termination specified in the tenant’s notice shall be at least 10 days after the date the tenant’s notice is given.
The Law, jurisprudence
Per the above statutory provisions, the question arises regarding the difference between a repair, a renovation, and a demolition. Quite often it is argued that a major renovation, at some point, should become a demolition. Contentiousness in the definition arises whereas the law holds that a tenant may return to a rental unit following a renovation but is without the same right following a demolition; and accordingly, much can be at stake. If the work is a "repair or renovation", and thus the tenant holds the right to return after the work is done and to do so at the same or similar rate of rent; however, if the work is a "demolition", the tenants right to return ends. Accordingly, the question of when does work becomes so extensive that a 'reno' is actually a 'demo'. Recently, the Divisional Court case of Two Clarendon Apartments Limited v. Sinclair, 2019 ONSC 3845 provided instructive guidance by stating:
 With respect to the interpretation of s. 50(1) of the Act, the Board concluded that there was a renovation here because the unit would be available in the same floor space, albeit reconfigured and extensively rebuilt. The Board considered the language of s. 50, especially the right of first refusal of a tenant pursuant to s. 50(3) if a unit is renovated. The Board also considered the purpose of this section, especially the tenant protection goal underlying s. 50(3).
 The Board concluded at paras. 13 and 14:
13. In a situation where the rental unit continues to exist, albeit in an extremely altered form, it is possible for the tenant to exercise a right of first refusal, because the rental unit is still there: the tenant may move back and continue the tenancy. In a situation where the rental unit is gone, it is not possible for the tenant to exercise a right of first refusal: the rental unit is no longer there and so the tenant cannot move back. The fact that the Act distinguishes renovations and demolitions by the tenant’s right of first refusal shows that the intention of these sections of the Act is to preserve tenancies where it is possible to do so.
14. Accordingly, a project will be defined as a renovation under the Act in a case where it is possible for the tenant to move back into the unit and a project will be defined as a demolition where it is not possible for the tenant to move back into the unit.
 The Landlord argues that the Board should have adopted the analysis in One Clarendon Inc. v. Ross (Ontario Rental Housing Tribunal, June 16, 1999) at paras. 15 and 16, where the member stated:
All the dictionary definitions offered by the parties would lead me to believe that to be consistent, a demolition of an apartment must achieve the same result as a demolition of a building – it must cause it to disappear and change irrevocably. What subsequently happens to the space occupied by the building or the apartment does not concern the Tribunal. The land on which the building stood could be used to construct a new one or be left empty, the space where the apartment was can be used to build a new unit or can be converted into a storage space.
That means, to my mind, such a degree of change that what was there disappears. In an ideal situation, a demolition of an apartment means a removal of all interior walls and doors, flooring, water and other fixtures, kitchen cabinets, electrical cabling – and then rebuilding it with new materials and fixtures, if that’s the intention of the owner. Anything substantially less than that degree of change can not [sic] be described as a demolition of an apartment.
 I note that this passage was obiter, as the member found that there was a renovation on the facts of that case. I note, as well, that the Board did not consider the overall purpose of the section, as the current member did.
 The decision in the present case was consistent with the result in Corbett v. Lanterra Developments, 2014 ONSC 3297 (CanLII) (Div. Ct.), at para. 14, where there was a demolition permit, and the construction resulted in different units from those demolished, so that the tenant could not move back into the rental unit.
 In my view, the Board’s approach to the definition of demolition was reasonable and consistent with the Act and modern principles of statutory interpretation.
 On the facts, the evidence supports the finding of a renovation. I note, although the Board did not mention this, that the affidavit evidence from the City Building Official states that the City had not granted a demolition permit, and the building permit required the same unit outside area as prior to the renovations.
It appears that where a residential door to a habitable unit will exist following a renovation, then the door is open for the tenant to choose to return; however, if the renovation work will be so significant that a unit capable of residential occupancy will not exist, the tenancy comes to an end. As was noted in Two Clarendon, work so significant as to constitute a demolition will usually require a building permit; however, such was said without stating that a demolition permit is an absolutely necessary element in the determination between renovation and demolition.
