Copyright
Canada's copyright law contains limits to the ability for parties to obtain injunctive relief for architectural works:
“40. (1) Where the construction of a building or other structure that infringes or that infringes or that, if completed, would infringe the copyright in some other work has been commenced, the owner of the copyright is not entitled to obtain an injunction in respect of the construction of that building or structure or to order its demolitions. (2) Sections 38 and 42 do not apply in any case in respect of which subsection (1) applies. R.S., 1985, c. C-42, s. 40; 1997, c.24, s.21”
