Not legal advice, as usual
The
Toronto Star's property law columnist lawyer
BOB AARON - a frequent authority relied upon by the CBC - has shed light on a midtown Toronto condo patio dispute over
a mere plastic trellis or screen. Offered worthwhile advice too.
It's a type of dispute played out thousands of times every year in America over U.S. flags, backyard sheds, outdoor art, religious icons, garden gnomes, , . . . etc.
This latest dispute at a
midtown Toronto townhouse involved some sorta mere plastic trellis or screen placed or secured against the metal enclosure of a small patio with the status of 'exclusive use common area'.
The size or particulars are tantlizingly left unspecified : was it 10 feet high ? was it 10 inches high ?
Unit owners
Mr & Mrs KUMER repeatedly refused condo Board demands to apply for permission to leave in place the trellis/screen. The Kumers would later argue ( through the course of arbitration & appeal to ONSC Ontario's Superior Court of Justice ) that
placing such was a FULLY PROTECTED, legislatively-authorized, reasonable exercise of their property rights. ( As in :
Ontario's Condominium Act 1998 S.O. 1998 ch C.19 https://ontario.cafcor.org/index.php?option=com_fireboard&Itemid=46&func=view&catid=9&id=19203#19203 )
Use of common elements by owners
116 An owner may make reasonable use of the common elements subject to this Act, the declaration, the by-laws and the rules. 1998, c. 19, s. 116. )
The Kumers also argued that
technically the "placed" item was NOT "erected" & thus
technically did not even trigger a condo Rule imposing prior submission & Board approval before "erection" of items on common elements. )
BUT ultimately the trellis/screen - whatever its particulars ignored by ONSC - got arbitrated & now judicially confirmed in violation by an ONSC judge.
It has been ordered removed with a partial arbitral award of $ 18 K also upheld against the owners.
To recap, with counsel the trellis owners again fail in arguments that :
- their plastic trellis/screen was literally NOT “erected” so not literally in by-lawed technical violation nor triggering any Board approval process, and
- that anyway the resultant usage was NOT more than “reasonable use” of the common elements
legislated as of right under the Act's section 116. There are arguably loose ends left in the judgment. Such arguably include that :
TOTALLY missing in action at ONSC : ONCA Ontario's
Court of Appeal 2009 decision upholding a lower court ruling that the following unapproved item
had not violated such gatekeeping authority at a different townhouse in the Hamilton area :
In a compact Hamilton condo townhouse backyard a non-approved 64 ft 3, ton and a half HOT TUB was held & upheld on appeal
NOT a section 98 violation -
Wentworth CC # 198 McMahon 2009 ONCA 870 https://canlii.ca/t/270k9
Anyway, back to mid-town Toronto the undetailed trellis' current status is moot, ONSC having noted that the appellant Toronto owners have sold the unit for $ 2.95 M.
Regardless of the 2009 Hamilton outcome & expectations of individual property owners, maybe it's a stretch to make adjudicators comfortable with visible non-uniformity laid on common elements at the whim of an individual unit owner.
. . . . whether as in : "
The flood-gates of Hell are threatening to open ! "
"And it may slow maintenance / increase costs in an unspecified amount ! . . .
( note :
there's ZERO said about whether the trellis can even be seen outside the unit. Nor how large it is. Nor whether management contractors cut patio grass within the patio . . trim weed growth . . . shovel snow . . . . whatever ? Exactly how does the trellis physically impede property operations - IF it even does ? Is the only genuine beef its mundane existence ?
Such sorta detail is germane to part of the decisive rationale, given the ambiguity confessed by the judge about whether a technical Rule is even literally being violated 
)
Further, "reasonable use" arguably appears to have been treated subject to not merely specific prohibitions within the governance documents, but to efficiency of physical property management operations.
Arguably treated that the Board's gate-keeping deserves deference due to its general obligations being imposed by condo law & site-specific documents & underwritten by all owners.
All the more reason to buy into a different community model unless one wants to accept what an arbitrator or judge decides are the disputed burdens & benefits of that scenario. 
( Or for that matter what use may sometimes be made of liens & charge-backs without a Section 98 agreement already in place . . . )
