For a seating chart you can go to ticketmaster.ca.
The 'home side' is the west side so your best seating is in sections C,D & E in the lower deck. The only concern with those seats though is that they are arena style seats that were retrofitted as there used to be bleachers. They are quite cramped and are the best argument for a new stadium.
If you like to be comforable, the upper deck is your choice. Sections 2A-5A are the best options there. I like to get row 2 if possible. The upper deck gives a great view of the whole field.
The west side is mostly taken up by old-time season ticket holders so if you don't mind being around the boisterous fans you will find a better selection of seats on the East side, sections U,V & W in the lower deck or 10A, 11A & 12A in the upper.
The current stadium will likely be replaced soon as it's really showing it's age. The views are good but the facilities will be a little disappointing. If you've been following the posts you know that there has been spirited debate over this proposal or that proposal for a replacement stadium. We're like that here - we take forever to make up our minds. Stadium aside, you are sure to enjoy the game.
