When were Canadian women seen as persons and when did they have the right to vote?

The first part depends upon who does the "seeing", and how you define "being seen as a person".

As for your second question, all female citizens aged 21 and over became eligible to vote in federal Canadian elections on 24 May 1918, regardless of whether they had yet attained that right in provincial elections. The right of women to vote, and to hold office, varied from province to province. For quite a long time, it also depended upon whether they owned property, were married, widowed or spinsters, and whether they were in the Armed Forces.

Canadian women were officially recognized as persons under the law on October 18, 1929. Prior to this date, women were not considered "persons" and therefore did not have the same legal rights as men. The change in legal status came about through the "Persons Case" – a famous constitutional ruling by the Judicial Committee of the Privy Council in Britain.

The right to vote for Canadian women was granted at different times depending on the province. The first province to grant voting rights to women was Manitoba in January 1916. Saskatchewan and Alberta followed suit later the same year. In 1917, British Columbia and Ontario extended the right to vote to women. The remaining provinces and territories then gradually followed suit. It is important to note that Indigenous women and women of other racial or ethnic minorities faced additional barriers and discrimination in accessing the right to vote, which were not completely addressed until later years.
