I did not go to Windsor, but:
You must submit all academic transcripts in a transfer application. They are no different from direct law school applications in this respect.
You would likely have to take torts in 2L as it is a standard 1L course across Canada. Depending on where you apply, you would also have to take other 1L courses (e.g. Constitutional Law at UVic, Legal Process at UofT).
The Windsor dual is an expensive path to transfer. Please appreciate that you may be unsuccessful in a transfer attempt and will have to pay tuition for the remainder of the program. Do not enter the program if you would not be happy receiving a JD from Windsor (which is a fine school).
