There are two things that I've always liked about Canadian Tire - they usually have very competitive prices on just about everything in their stores, and they have the best return policy on the planet. If you don't like what you've bought, return it, typically with no questions asked. Which is probably part of the reason they've been in business for so long.

A lot of people don't recommend bit sets. The argument is that you end up using only a few of the bits, and the price for each bit you use will therefore be disproportionally higher than if you used all the bits. There is obviously some logic to this. Which is why I recommend that you carefully inspect the bit set to see how many of them your are likely to use on a regular basis. Then use this number to calculate your per bit cost. For professional woodworkers it is usually more economical to purchase bits separately. However, for hobbyist woodworkers, DIYers, and homeowners, bits sets can often be the better choice, particularly if you don't already have many bits.

The Mastercraft Maximum Router Bit Set contains 40 different 1/4" shanked bits in 26 different styles. These are good quality bits - not professional quality, but very serviceable. The top quality bits on the market use micro grain carbide. These bits have a metallic titanium finish and titanium carbide cutting edges. Titanium improves surface hardness and increases lubricity.

There were some noticeable pits on the brazing, and and the cutting edges are not as highly polished as on professional quality bits. I've been using these bits intermittently over the past two months, and am quite satisfied with their performance. I still use a professional quality bit for precise joinery and when I want the cleanest of cuts. However, for general routing tasks, where the visual quality of the cut is not overly important; when I'm routing sheet goods for patterns and shop jigs; or when I'm doing carpentry work, I'll use the Mastercraft bits. This is proving to be very economical, as it means my more expensive bits will last longer between sharpenings or replacement. One of the limitations of this set is that all the bits have a 1/4" shank. All things being equal I prefer 1/2" shanked bits. They have about four times the mass of 1/4" shank bits, which means less bit  vibration and less heat build-up. But, if you primarily use a palm (trim) router, then this is moot point.

This 40 piece set costs $250, or $6.25 per bit., which is one of the best values I've seen in bet sets in some time. Even if you use only half the bits regularly you're averaging about $12 per bit - still very good value. There are only seven that I'll never likely use: the lettering, keyhole, veining, 90° V-groove, core box, panel pilot, t-slotting, and three others I'll seldom use (ogee, ogee with fillet, classic cove). So that makes it $8.30 per bit for the ones I'll get use from. Done deal.

If you are a hobbyist woodworker, DIYer, or homeowner, or if you are just getting into woodworking, then this is a good set to consider.
