Here are some of the best sportsbook welcome‑bonus offers available to Canadian bettors (current as of Sept 28, 2025). I list each offer, the main benefit, quick caveats (wagering/min deposit or province notes) and source(s) so you can check full terms before claiming.

Top welcome offers (summary)

• Sports Interaction — 125% match up to CA$250. Strong overall offer for Canadian customers; easy to claim and usable across many markets. Check specific wagering rules and provincial availability. (Covers.com)
• BetPlays — Very large dual welcome (advertised up to CA$12,000 via deposit + first‑bet match). Best for high‑rollers but with big wagering/deadline requirements — read the short promo window and wagering terms carefully. (Covers.com)
• 888Sport (Canada) — 100% bonus up to CA$500 (often packaged with a small casino bonus). Good if you want both sportsbook + casino options; compare the bet‑match and playthrough rules. (Covers.com)
• BetMGM (Canada) — Frequently offers a competitive new‑user promo (bet credits/match + spins on related casino). Popular app and broad market coverage; promo details vary by province and date. Always confirm the current BetMGM CA landing page. (casinobetmgm.ca)
• 10Bet / PowerPlay / other mid‑tier books — Several reputable international books running 100–125% deposit matches up to ~$150–$500 and first‑bet credits. Good options if you want lower rollover requirements or specific markets. Compare offers on aggregator sites. (SportsbookReview.com)

Why these made the list

• Value vs practicality: some books (e.g., BetPlays) advertise huge maximums but require large deposits and heavy wagering; Sports Interaction and 888Sport present more balanced, usable packages for most bettors. (Covers.com)
• Market access & app quality: BetMGM and similar established brands offer wide market coverage and polished apps, which matter when you’ll use a bonus across live and pregame markets. (casinobetmgm.ca)

Quick practical tips before you claim

1. Always read the full T&Cs: minimum deposit, qualifying markets/odds, wagering/rollover, expiry of bonus funds, max stake while using bonus, and withdrawal restrictions. These vary a lot between books. (Covers.com)
2. Province restrictions: some promos are limited or adjusted by province (Ontario vs. other provinces). Confirm the bonus is valid where you live. (readwrite.com)
3. Compare effective value: a “100% match up to $500” with a 12x rollover can be far worse than a $250 match with no/low rollover — prioritize low wagering and reasonable expiry windows. (Covers.com)
4. Use aggregator/review sites for current best promos: promotions change frequently — aggregator pages (Covers, SportsbookReview, etc.) keep lists and verification dates that help you pick the best current deal. I used recent aggregator checks dated Sept. 2025. (Covers.com)
5. Responsible gambling: treat bonuses as marketing tools — stake only what you can afford and check responsible‑gambling tools offered by the site.
