Are you allowed to take a gap year in the middle of your studies and enrol in another institution for a year?

This might sound stupid but genuine question.

I have already submitted all my law school applications. I also will be applying to some masters programs that i could only do with funding. Thing is, i dont think ill be able to get funding this year. The masters program would only be a year.

Is it possible to do McGill law for a year, then take a gap year and enrol in another institution if i get funding next year? Then after that one year in a masters i come back to McGill to finish my law degree?

Is this dumb.
