Buying Points in Canada: Alternate Lines Explained

Every sportsbook serving Canadian bettors offers alternate lines, and most players either ignore them entirely or use them badly. The concept is simple enough: instead of taking the posted spread, you move it a point or two in your favour and accept worse odds in exchange, or move it against yourself and get better odds. Buying points is the informal name for the first of those, and it is one of the few betting decisions where the correct answer can actually be calculated rather than argued about.

The short version is that buying points is usually a losing proposition, with a small number of clearly defined exceptions where it is one of the sharpest moves available. Knowing which situation you are in is worth more than any handicapping angle, because it applies to every single bet you place on a spread or total.

How alternate lines work

When a book posts a football game at a favourite of minus 3 at standard odds, it will also list alternates. Minus 2.5 might come with meaningfully worse odds. Minus 1.5 worse again. Plus 1 on the same team would carry a substantial price. Each half point of movement has a cost, and that cost is not uniform.

The book calculates that cost from the probability that the game lands exactly on the numbers you are crossing. Move a spread from minus 3 to minus 2.5 and you are buying protection against exactly one outcome: the game finishing with a three-point margin. Move from minus 8 to minus 7.5 and you are buying protection against a much rarer eight-point margin. The first purchase is worth far more than the second, and a well-run sportsbook prices it accordingly.

Key numbers and why they dominate

In football, final margins cluster heavily on three and seven because of how scoring works. A large share of all NFL and CFL games finish with a margin of exactly three points, and seven is the clear second. Four, six and ten form a secondary tier. Margins of two, five and eight are comparatively uncommon.

This distribution is the entire reason buying points is sometimes correct. A half point that crosses a key number removes a genuinely likely outcome from your losing column. A half point that crosses a dead number removes almost nothing.

In basketball, the distribution is far flatter. NBA margins spread across a wide range with no equivalent to football's three, which makes buying points in basketball almost uniformly poor value. Hockey and soccer, with their low scoring, have their own patterns entirely, and puck lines behave so differently that they deserve separate treatment, which we cover in our Canadian sportsbook guide.

The arithmetic of a half point

Here is the framework. To decide whether buying a half point is worth it, compare two things: the extra price you pay in odds, and the probability that the game lands exactly on the number you are crossing.

If a half point costs you roughly ten percent in added price and the number you cross occurs in roughly ten percent of games, you are paying fair value and gaining nothing. If the number occurs less often than the price implies, you are losing money. If it occurs more often, you are gaining.

In practice, sportsbooks understand key numbers very well, and they charge a premium for the half points that matter most. Crossing the most valuable numbers in football is often priced at or beyond fair value. Crossing the least valuable numbers is priced far above fair value relative to what you gain.

The practical takeaway for most Canadian bettors:

• Buying off a key number in football can be defensible when the price offered is modest, particularly when moving onto the safe side of three.
• Buying points away from key numbers is close to always bad. You are paying a real premium to remove an outcome that rarely occurs.
• Buying points in basketball is generally poor value. The margin distribution is too flat for any half point to be worth much.
• Selling points, taking worse numbers for better odds, is worth examining when you are moving off a dead number, because books often underprice what they are giving back.

Alternate totals follow the same logic

Totals have key numbers too, though they are less dramatic. In football, totals cluster around numbers ending in three and seven for the same scoring reasons, plus the round numbers where public betting concentrates. In hockey, the total is so tightly packed around five and a half and six that a single half point is enormously significant, which is why alternate totals in NHL markets carry steep prices.

Weather-affected games are a special case. When wind or cold pushes a football total down, the market moves quickly, and alternate lines can lag the main number briefly. That is a genuine, if rare, opportunity. We looked at how weather moves Canadian betting markets in more depth elsewhere in our sports betting coverage.

Where alternate lines are genuinely useful

Beyond the key-number question, alternate lines serve two legitimate purposes that have nothing to do with value hunting.

The first is bankroll shaping. A heavily bought-down spread at short odds behaves more like a moneyline bet: higher win rate, smaller return. A sold-up spread behaves like a small long shot. If you want to change the variance profile of your betting without changing your handicapping, alternate lines are the cleanest tool available. That said, the cost of that reshaping is real, and it should be a deliberate choice rather than a habit.

The second is correlation. Alternate lines are the raw material of teasers, and understanding how a two-point move is priced individually tells you a great deal about whether a multi-leg product is offering you a fair deal. If a book prices individual alternate lines expensively but packages them into a teaser at a flat price, the teaser may be the better buy, and vice versa.

Line shopping matters more than the buy

The single biggest mistake Canadian bettors make with alternate lines is buying a half point at one sportsbook when another book is already offering that number as its main line at standard odds. Spreads and totals differ between operators constantly, and a free half point obtained by opening a second account beats any purchased half point.

This is why maintaining accounts at several licensed operators is the foundation of everything else. Ontario residents have a deep regulated market to choose from, and our Ontario sports betting guide compares which books consistently post the sharpest numbers. Bettors in Alberta now have a provincially regulated option as well, detailed in our Alberta betting guide.

A simple rule to carry with you

Before you buy a point, ask one question: what outcome am I actually removing? If the honest answer is a common one, and the price is fair, consider it. If the answer is an outcome you cannot remember seeing this season, you are paying for comfort rather than equity.

Alternate lines are a tool, not a strategy. Used deliberately around football's key numbers, they can add a fraction of a percent to your long-run results. Used reflexively because a shorter spread feels safer, they are one of the quietest ways a sportsbook takes money from otherwise competent bettors.
