For plan C it may be helpful the document 'Database Protection in Canadian Laws' [1]. It is hard to assume conclusions from a legal text but I think it can be 'fair dealing' (similar to US fair use) as it is not 'unfair competition' and only factual data without substantial text.

> Plan C is to scrape their site. Take for example
> http://www.historicplaces.ca/en/rep-reg/place-lieu.aspx?id=16402 . It's
> is straightforward to get the:
> * PlaceId (number in the url)
> * Location (street, city, Canada)
> * Latitude
> * Longitude
> * Name
> * Construction date
> This appears appears to be factual information, so probably not
> copyrightable. I don't dare touch the description. Would this be covered
