Which Canadian province has a setting sun on its flag?

The flag of British Columbia is based upon the shield of the provincial arms of British Columbia. At the top of the flag is a rendition of the Royal Union Flag, defaced in the centre by a crown, and with a setting sun below, representing the location of the province of British Columbia at the western end of Canada.

From 1870 to 1906, British Columbia was occasionally represented by a modified British blue ensign featuring various forms of the great seal of the Colony of British Columbia. The current flag of British Columbia was based upon the 1906 arms of the province, designed by Arthur John Beanlands, the canon of Christ Church Cathedral. Originally, the arms featured the Union Flag on the bottom. This was changed as it conflicted with the expression "The sun never sets on the British Empire".
