It depends on your profile.
MS courses usually require a very strong academic profile with minimum GPA of 3.5 at Canadian universities.
In case of diplomas, you can get admission to good universities with minimum percentage of 65% (approx).
The reason being that the MS courses are very academically rigorous, which diplomas focus a bit more on the practical aspect as well. So, the ultimate choice depends on your profile, as both courses can lead to well-paying jobs.
