Still illegal in canada[0]:

Although the type of conduct that might constitute champerty and maintenance has evolved over time, the essential thrust of the two concepts has remained the same for at least two centuries. Maintenance is directed against those who, for an improper motive, often described as wanton or officious intermeddling, become involved with disputes (litigation) of others in which the maintainer has no interest whatsoever and where the assistance he or she renders to one or the other parties is without justification or excuse. Champerty is an egregious form of maintenance in which there is the added element that the maintainer shares in the profits of the litigation. Importantly, without maintenance there can be no champerty.
