It seems like the Macbook Pro might be a close fit but I think will work. I found that the dimensions for it are 26.7cmx39.3cmx2.5cm.

There are two pouches on this pack.

The hanging padded compartments dimensions are a height of 31cm a width of 28cm and a depth of 3 or 4cm. There is a bit more clearance over the top for the height to make it 37cm tall but those extra 6cm are not within the pouch itself.

The other pouch is a mesh pouch on the front of the inside the pack opposite to the hanging pouch. Its dimensions are a height of 27cm by a width of 28cm and a depth of 3 or 4cm.

There are 3 pouches on the outside of the bag which would be good for storing peripherals. There are 3 different sizes of pouches which I would describe as a small, medium and large pouch.

It seems as though your laptop should be good for the size although the tablet seems a bit big for this bag. I might recommend MEC Darwin 2 Daypack (5013-106) or the MEC Darwin Shoulder Bag (5013-105) which would be a better fit for the computer. For being able to fit both in I would suggest the SealLine Urban Shoulder Bag (5015-630) whose dimensions are 46 x 38 x 13cm which will be your good bet if your wanting to get both of them in there. Im sure with a little rearrangement it would fit in nicely. The best bet is probably the MEC Brenta Courier Bag (4015-213) since it compartment is 43 x 30 x 56cm.

The dimensions of the MEC Gigabyte Computer Dayback are:

Height: 47 cm
Width: 32 cm
Depth: 16 cm

Laptop sleeve dimensions are:

Height: 28 cm
Width: 28 cm
Depth: 5 cm
